FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with surgery is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about surgery, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to surgery, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on surgery. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to surgery, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on surgery. The Editors

CHAPTER 1. STUDIES ON SURGERY Overview In this chapter, we will show you how to locate peer-reviewed references and studies on surgery.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and surgery, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “surgery” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Surgery and the Patient With Alzheimer's Disease Source: Geriatric Nursing. 9(4): 227-229. July-August 1988. Summary: This journal article discusses preoperative precautions and education for patients with Alzheimer's disease. Memory loss may make medical history taking difficult, therefore, a family member or guardian should be consulted. Behavioral changes such as aggressiveness, anxiety, depression, agitation, insomnia, and paranoia, may necessitate the use of antipsychotics, tranquilizers or antidepressants. However, drugs should be administered with extreme caution and in reduced dosages since Alzheimer's disease patients are extremely sensitive to medications. Use of preoperative medication in patients with advanced Alzheimer's disease should only be used for analgesia or agitation. Preoperative education for both the patient and family is essential in reducing confusion and anxiety and providing understanding and support.

Surgery
Preoperative instructions should be written for reinforcement. Surgery for most patients with Alzheimer's disease is performed under general anesthesia. Since delayed recovery from anesthesia is common, prolonged observation will be required in the recovery room and patient care unit. Nurses should instruct both patients and family members in any continued postoperative care to be followed at home, including drug therapy. As reinforcement, patients should receive concise, written instructions. With supportive assistance and an understanding of the behaviors associated with Alzheimer's disease, nurses can help patients through a surgical procedure. •
Controlled Trial of Arthroscopic Surgery for Osteoarthritis of the Knee, A Source: New England Journal of Medicine. 347(2): 81-88. July 11, 2002. Summary: This journal article provides health professionals with information on a randomized, placebo-controlled trial that assessed the efficacy of arthroscopic surgery of the knee in relieving pain and improving function in patients with osteoarthritis (OA). The study population consisted of 180 patients with knee OA who were randomly assigned to receive arthroscopic debridement, arthroscopic lavage, or placebo surgery. Patients in the placebo group received skin incisions and underwent a simulated debridement without insertion of the arthroscope. Patients and assessors of outcome were blinded to the treatment group assignment. Outcomes were assessed at multiple points over a 24 month period with the use of five self reported scores (three on scales for pain and two on scales for function) and one objective test of walking and stair climbing. A total of 165 patients completed the trial. The study found that at no point did either of the intervention groups report less pain or better function than the placebo group. For example, there was no difference in knee pain between the placebo group and either the lavage group or the debridement group at 1 year or 2 years. Similarly, there was no significant difference in arthritis pain between the placebo group and the lavage group or the debridement group at 1 or 2 years. Furthermore, at no time point did either arthroscopic intervention group have significantly greater improvement in function than the placebo group. For example, there was no significant difference between the placebo group and either the lavage group or the debridement group in the self reported ability to walk and bend at 1 year or at 2 years. In fact, objectively measured walking and stair climbing were poorer in the debridement group than in the placebo group at 2 weeks and 1 year and showed a trend toward worse functioning at 2 years. Lacking evidence of the superiority of the arthroscopic treatments over the placebo procedure in relieving pain or improving function, researchers considered whether the 95 percent confidence intervals for the differences in outcomes between each arthroscopic procedure and the placebo procedure included clinically important differences. At almost all time points during follow up, the confidence intervals excluded the minimal important differences used in the study. The article concludes that the outcomes after arthroscopic lavage or arthroscopic debridement were no better than those after a placebo procedure. 2 figures, 3 tables, and 35 references. (AA-M).

malignant lesions, control bleeding, and cut or excise tissue. The major modalities in electrosurgery are electrodesiccation, fulguration, electrocoagulation, and electrosection. In electrodesiccation, an active electrode touches or is inserted into the skin to produce tissue destruction. In fulguration, the electrode is held away from the skin to produce a sparking at the skin surface and more shallow tissue destruction. Electrocoagulation is ideal for clotting small blood vessels in deep and superficial surgery. In electrosection, the electrode is used to cut tissue. Electrosurgery can be used for incisional techniques that produce full thickness excision of nevi, for shave techniques that produce partial thickness removal of superficial lesions, and for removal of vascular lesions such as hemangiomas or pyogenic granulomas. When selecting an electrosurgical unit, the physician must determine whether the equipment will be used for electrosection and cutting techniques, what safety features are available, what the cost is for purchasing and operating an electrosurgical unit, and what policies and warranties the manufacturer has for the equipment. The correct output power can be determined by starting low and increasing the power until the desired outcome is attained (destruction, coagulation, or cutting). Smaller cherry angiomas can be electrocoagulated lightly. Larger cherry angiomas may be easier to treat by shaving them first then electrocoagulating or desiccating the base. The elevated portion of pyogenic granulomas can be shaved off with a scalpel or a loop electrode using a cutting/coagulation current. The base of the lesion is curetted to remove the remaining tissue and then electrodesiccated. Complications such as burns, shocks, and transmission of infection can be prevented by careful use of the electrosurgical equipment. 4 figures, 3 tables, and 6 references. (AA-M). •
Arthroscopic Surgery for Athletic Elbow and Wrist Injuries Source: Clinics in Sports Medicine. 20(1): i-xiii,1-222. January 2001. Summary: This journal provides health professionals with information on arthroscopic surgery for athletic elbow and wrist injuries. The journal begins with an article on the etiology, clinical presentation, diagnosis, and treatment of osteochondritis dissecans of the elbow. This is followed by an article that explores the evaluation and arthroscopic treatment of posterior impingement of the elbow in athletes. The next article focuses on valgus instability of the elbow in athletes. Topics include clinical and functional anatomy, diagnosis, nonoperative and operative treatment, and postoperative management. The fourth article discusses the diagnosis and treatment of posterolateral rotatory instability of the elbow. This is followed by an article that examines fracture dislocations of the elbow in athletes, focusing on simple and complex dislocations and radial head, coronoid, and olecranon fractures. The next article deals with the etiology, epidemiology, pathophysiology, diagnosis, and treatment of epicondylitis in the athlete. The seventh article focuses on the anatomy, clinical presentation, treatment, and rehabilitation needed for return to sports after various nerve entrapments. This is followed by an article that offers concise procedural advice for arthroscopic treatment of flexion contractures of the elbow. The next article provides an overview of presentation, diagnosis, and nonoperative and operative treatments for scapholunate instability in athletes. The tenth article focuses on a study that investigated a technique for arthroscopic stabilization of the lunotriquentral joint by disk carpal ligament suture plication with arthroscopic reduction and internal fixation of the joint with interosseous Kirschener wires and reviewed the postoperative clinical outcome of a case series of 20 consecutive patients. The next article discusses the classification, diagnosis, debridement, and repair of triangular fibrocartilage complex tears in the athlete. This is followed by articles that describe carpal and distal radius fractures in athletes. Carpal fractures include scaphoid, hamate hook, triquetral, pisiform, trapezium, trapezoid,

capitate, and lunate fractures. The final article discusses the causes, pathophysiology, clinical presentation, and treatment of nerve injuries of the elbow, wrist, and hand in athletes. 80 figures, 4 tables, and numerous references. •
What's New in Adult Reconstructive Knee Surgery Source: Journal of Bone and Joint Surgery. 83-A(9): 1444-1450. September 2001. Summary: This journal article provides health professionals with information on new developments in adult reconstructive surgery. The article summarizes topics presented at selected orthopedic meetings and those addressed in various articles. The article highlights findings concerning conservative treatment of patients with mild to moderate osteoarthritis of the knee, focusing on the effectiveness of glucosamine and chondroitin, manual physical therapy, and exercise. Investigations related to surgical treatment options focused on total knee arthroplasty following high tibial osteotomy, unicompartmental knee arthroplasty, alignment of the femoral and tibial components in total knee arthroplasty, cruciate ligament retaining and cruciate substituting designs, use of mobile bearing protheses, simultaneous femoral osteotomy and total knee arthroplasty, and revision total knee arthroplasty. Other topics include blood conservation in total knee arthroplasty, soft tissue balancing, fixation techniques, the diagnosis and treatment of infection in association with total knee arthroplasty, patellofemoral articulation as a common source of complications in total knee arthroplasty, and polyethylene wear. 9 references.

Endoscopic Spinal Surgery: What Future Role? Source: Journal of Musculoskeletal Medicine. 18(11): 518-520,525-528. November 2001. Summary: This journal article, the sixth in a special series of articles on the evaluation and management of back pain, provides health professionals with information on traditional approaches to spine surgery, the evolution of alternative approaches, and the current state of endoscopic spinal surgery. Arthroscopic joint surgery has played a major role in promoting understanding of knee pain and shoulder pain. Now that endoscopic spinal surgery can be performed, spinal conditions previously not considered with traditional surgical techniques may be evaluated, diagnosed, and managed. Painful and nonpainful anatomic parts can be visually correlated with imaging studies when spinal probing is accomplished with the patient in an aware state. Patients not responding to traditional surgical methods now may find lasting pain relief with endoscopic spine surgery directed toward the pain generator. Perhaps the ideal lesion for selective endoscopic diskectomy is far lateral, extraforaminal disk herniation. As with arthroscopic knee surgery, the risk of serious complications or injury with endoscopic spinal surgery is low. Dysesthesia, the most common postoperative complaint, occurs about 5 percent of the time and is almost always transient. The learning curve for the minimally invasive procedure is high, but advances in training, techniques, and instrumentation will likely make it routinely available in the near future. Except for pregnancy, there are no absolute exclusion criteria but only relative contraindications. 3 figures and 16 references. (AA-M).

Surgery vs Orthosis vs Watchful Waiting for Hallux Valgus: A Randomized Controlled Trial Source: JAMA. Journal of the American Medical Association. 285(19): 2474-2480. May 16, 2001.
Studies

Summary: This journal article provides health professionals with information on a randomized controlled trial that compared the effectiveness and costs of surgical and orthotic treatments in patients with hallux valgus with no treatment. The study was conducted in four general community hospitals in Finland from 1997 to 1998, with a followup period of 12 months. The study population consisted of 209 consecutive patients with a painful bunion and a hallux valgus angle of 35 degrees or less. Seventyone patients were randomized to the surgical group, 69 to the orthosis group, and 69 to the control group. Main outcome measures were pain intensity during walking on a visual analog scale, patient assessment of global improvement, number of painful days, cosmetic disturbance, footwear problems, functional status, and treatment satisfaction. The study found that followup rates at 6 and 12 months were 99 percent and 98 percent, respectively. At 6 months, pain intensity decreased more in the surgical group than in the control group and more in the orthosis group than in the control group. At 1 year, 83 percent, 46 percent, and 24 percent in the surgery, orthosis, and control groups, respectively, thought they had improved compared with baseline. Number of painful days, cosmetic disturbance, and footwear problems were the least and functional status and satisfaction with treatment were the best in the surgical group. Total foot care costs were the least in the control group. Excluding the costs of intervention, health care costs were the least in the orthosis group. The article concludes that surgical osteotomy is an effective treatment for painful hallux valgus. Orthoses provide short tem symptomatic relief, so this treatment option may be considered when patients with disabling hallux valgus pain must wait for surgery. 2 figures, 4 tables, and 22 references.

Cosmetic Laser Surgery Source: FDA Consumer. 34(3): 34-37. May-June 2000. Summary: This journal article provides the general public with information on cosmetic laser surgery. Laser resurfacing is used to remove wrinkles and lines caused by sun damage and facial expressions, acne scars, some folds and creases around the nose and mouth, and precancerous and benign superficial growths. Lasers are revolutionary surgical tools because they can cut through tissue without causing excessive bleeding, their energy can reach areas within the body more easily than a scalpel, and they can let surgeons target very specific types of tissues without affecting nearby tissue. Not everyone is an ideal candidate for laser resurfacing because certain people with very sensitive skin cannot tolerate the medications and lubricants used on the skin during healing. In addition, darker skinned ethnic groups are not candidates because laser resurfacing alters skin color too dramatically and unpredictably. People who expect instant results are also not good candidates. Certain complications occur with laser resurfacing, including a prolonged redness of the skin, tenderness, easy flushing, and some pigmentary changes. Although most of these complications are temporary, there are some more serious and possibly permanent complications, including hypopigmentation and scarring. There is no national policy for credentialing health professionals planning to practice laser surgery, so consumers must be very careful when selecting a practitioner. They need to interview several doctors, ask the right questions, and evaluate the doctors' answers and credentials.

Project Title: 1H AND 31P MRSI FOR EPILEPSY LOCALIZATION Principal Investigator & Institution: Laxer, Kenneth D.; Professor of Clinical Medicine and Neuro; Neurology; University of California San Francisco 500 Parnassus Ave San Francisco, CA 94122 Timing: Fiscal Year 2001; Project Start 01-MAY-1994; Project End 31-MAR-2004 Summary: The long term goal of this application is to improve the outcome of seizure surgery by better presurgical localization of medically refractory epilepsy using a combination of neuroimaging techniques including magnetic resonance imaging (MRI), 1H and 31P MR spectroscopic imaging (MRSI), and 18F-PET. These techniques will be directed at three groups with medically refractory epilepsy who are being evaluated for seizure surgery (numbers for 5 years): 1)patients with medial temporal lobe epilepsy in whom MRI is non-concordant i.e., MRI shows no abnormality, or an abnormality contralateral to the EEG-defined seizure focus (NC-mTLE, n=75), 2) patients with nonlesional neocortical epilepsy (NE, n=100), and 3) children with Infantile Spasms (IS, n=100). NC-mTLE and NE patients frequently require invasive EEG recording, have less than a 50 percent probability of becoming seizure free with surgery, and are often not considered for surgery. Post-operative surgical outcome will be analyzed in relation to the pre-operative neuroimaging findings. Hypotheses: 1) NC-mTLE -Patients with medically refractory mTLE without MRI concordance, who have 1H and 31P MRSI measures concordant with the EEG localization (i.e., lobe and side), will have a significantly better post surgical outcome than patients without MRSI concordance. 2a) NE - NE patients without lesions on MRI, will have 1H and 31P MRSI concordant with the EEG localization (i.e., lobe and side), and this concordance will be greater than that provided by 18FDG-PET. 2b) NE - NE patients, who have 1H and 31P MRSI measures concordant with the EEG localization will have a significantly better post surgical outcome than patients without MRSI concordance. 3a) IS - Children with medically refractory Infantile Spasms will have 1H and 31P MRSI concordant with the seizure focus determined by a combination of two or more studies (VET, 18FDG-PET, and/or MRI) and this concordance will be greater than that provided by MRI or 18FDG-PET. 3b) IS - IS children, who have 1H and 31P MRSI concordant with the localization provided by the other clinical and imaging studies will have a significantly better post surgical outcome than patients without such concordance. These studies are expected to lead to improved surgical outcome, and to reduce unnecessary surgery, in patients with intractable epilepsy.

Project Title: A MULTI-CENTER STUDY OF EPILEPSY SURGERY Principal Investigator & Institution: Spencer, Susan S.; Professor; Neurology; Yale University 47 College Street, Suite 203 New Haven, CT 065208047 Timing: Fiscal Year 2001; Project Start 04-APR-1996; Project End 31-MAY-2006 Summary: (Applicant's Abstract): Nearly one percent of the United States population has epilepsy. By some estimates more than 20% of those patients are inadequately treated despite a growing number of anti-epileptic medications. Resective surgery is increasingly used to treat this population, despite its high costs. Outcome with regard to seizures following epilepsy surgery has rarely been systematically or prospectively assessed in large samples, and quality-of-life, cognitive, neurologic, and psychiatric status following epilepsy surgery in the long or short-term are largely unexplored. Over the past 5 years we enrolled a 400 patient cohort in the first multi-center study of epilepsy surgery. Evaluation and treatment of these patients incorporated uniformity and technological advances, as well as reliable and validated baseline and follow-up measures of psychiatric status, cognitive function, quality-of-life, seizure severity and frequency, productive activities, and family dynamic. We propose to complete two-year follow-up on the full cohort, and extend follow-up to 5 years. We seek to define the occurrence and predictors of seizure remission, as well as improvements in quality-oflife, and stability or improvement in psychiatric, cognitive and neurologic status, based on factors in the preoperative profile and postoperative observations. We also propose to define relapse and continued remission off all medications and the predictors for successful medications withdrawal, an important yet unstudied aspect of epilepsy surgery. Our primary goals are: 1. to study the probability of achieving 1, 2, and 5 year seizure remission after epilepsy surgery, and the probability of relapse after remission over a total 5 year follow-up, as well as the prognostic significance of specified preoperative and postoperative factors; 2. to determine the probability of relapse and prediction of relapse in patients who discontinue medications after 2 year remission, and prognostic factors for successful outcome; 3. to assess self reported quality-of-life and employment status yearly for 5 years after resective epilepsy surgery, and to determine the magnitude and time course of change, and the extent to which seizure response and medication changes are associated with alterations in self-perceived health and employment; 4. to identify the nature and magnitude of changes in cognitive and neurologic status after resective epilepsy surgery, the factors that predict changes, and their resilience and functional impact over 5 years of follow-up; and 5. to prospectively assess changes in behavior and psychiatric profile yearly for 5 years and examine predictive factors in long-term prognosis of depression, anxiety and other psychiatric diagnoses, as well as family dynamics. The proposed study represents a unique multicenter effort that will result in the largest systematic study of epilepsy surgery to date, and will provide definitive answers to key questions regarding the outcomes of epilepsy surgery, their measurement, and their prediction in a contemporary patient population.

Project Title: ADVANCING CLINICAL RESEARCH IN PEDIATRIC SURGERY Principal Investigator & Institution: Lally, Kevin P.; Surgery; University of Texas Hlth Sci Ctr Houston Box 20036 Houston, TX 77225 Timing: Fiscal Year 2002; Project Start 01-JUN-2002; Project End 31-MAY-2007 Summary: Congenital disorders requiring major pediatric surgical intervention are infrequent and present complex management problems. Most pediatric surgical studies are methodologically weak, single-center studies, and improved outcomes are likely to require a series of multi-center studies of exemplary quality. The applicant, Dr. Kevin Lally, the A.G. McNeese Professor and Chief of Pediatric Surgery at UT Houston, is a leader in promoting such studies. He has participated in 19 diaphragmatic hernia (CDH). CDH occurs in 1 per 2-4,000 live births; 35% of infants die; survivors are ventilated a mean of 18 days; and 34% have chronic lung disease. K24 funding is requested to substantially increase Dr. Lally's time for 1) Clinical Research including: a) A Multi-center placebo- controlled, randomized trial of antenatal steroids for infants with prenatally diagnosed CDH to improve their oxygenation and reduce time to ventilator independence. Fifteen centers have committed to participate; 7 have IRB approval; and 8, including UT-Houston, have GCRCs. The UT-Houston GCRC provides substantial statistical and database support for this trial. Collaborators at UT Houston include Drs. Larry Gilstrap and Jon Tyson, both experienced in steroid trials, and wellfunded investigators in steroid trials, and well-funded investigators in the NICHD Maternal-Fetal and Neonatal Research Networks; and b) Extensive analyses of the CDH registry to define improved predictors of outcome, assess geographic differences and temporal trends, and develop hypotheses and descriptive data needed to design trials to improve outcome. This database has strict quality control, data on 1650 infants and 48 institutions now participate. 2) Mentoring Dr. Lally is a talented mentor; 3 current mentees have recently received a K08 award, a K23 award, and a Young Investigator
Studies 11
Award. To enhance his mentoring skills, promote the funding and productivity in his Division of Pediatric Surgery, and augment his methodologic skills in clinical research, Dr. Lally will complete the NIH funded Clinical Research Curriculum work and assist with mentoring teams for young investigators in the Curriculum. He will also conduct systematic reviews of the Cochrane Collaboration and complete the Master's Degree Program in Clinical Research at UT-Houston. K24 funding will help Dr. Lally with his research and mentoring to advance the quality of clinical research in pediatric surgery, develop an expanded international trials network, and improve the outcome of highrisk infants.

Project Title: AGING AND COGNITION AFTER CARDIAC SURGERY Principal Investigator & Institution: Reves, Joseph G.; Anesthesiology; Duke University Durham, NC 27706 Timing: Fiscal Year 2001; Project Start 15-FEB-1991; Project End 31-JAN-2004 Summary: Elderly patients are increasingly undergoing cardiac surgery and this trend is forecasted to continue. A very common and disturbing consequence of this surgery is deterioration in cognitive function. This impairment can be as high as 83% in the hospital and continue in up to 30% or more of patients for over a year. Elderly patients are particularly susceptible to this neurocognitive consequence of life- preserving surgery. This cause of cognitive dysfunction is postulate to be a result of cerebral emboli that occur during cardiac surgery. The cause of cognitive dysfunction is postulated to be a result of cerebral emboli that occur during cardiac surgery, which are impossible to prevent, and therefore strategies to protect the brain must be developed. It has become standard practice in cardiac surgery to allow the hematocrit advantages to blood flow during hypothermic cardiopulmonary bypass and fear of adverse consequences of transfusion. It is not known whether this hemodilution (50% reduction in oxygen carrying capacity of the blood) contributes to brain injury and cognitive impairment. We will test the hypothesis that preserving oxygen carrying capacity of the blood by limiting the amount of hemodilution during cardiopulmonary bypass improves cerebral protection. A prospective, randomized trial in 370 patients will be conducted in which half of the patients will be assigned to moderate hemodilution (hematocrit of greater than or equal to 27%-treatment group) and other half to profound hemodilution (hematocrit 15-18%-current practice group). Change in cognitive function over the first year after surgery will be compared between the groups. A secondary aim is to determine if serum markers of glial (S100beta) and neuronal (neuron-specific enolase) brain injury predict the changes in cognitive function. A positive association of brain injury markers with cognitive change will allow earlier detection and support the hypothesis that the cognitive changes are a result of brain ischemia. New knowledge gained in this study would be immediately transferred to clinical practice and could reduce the severity of cognitive impairment. The new information regarding cerebral protection would also have application in all ischemic brain syndromes including stroke. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: BEHAVIORAL MULTIMEDIA FOR ACL RECONSTRUCTIVE SURGERY Principal Investigator & Institution: Brewer, Britton W.; Virtual Brands 10 Echo Hill Rd Wilbraham, MA 01095
12 Surgery
Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2004 Summary: (provided by applicant): Approximately 80,000 Americans sustain acute tears of the anterior cruciate ligament (ACL) of the knee each year, with associated healthcare costs estimated at roughly 1 billion dollars annually. Surgical reconstruction followed by an extended rehabilitation period is commonly recommended for ACL tears. The purpose of this STTR project is to develop a comprehensive behavioral multimedia package designed to reduce preoperative anxiety, decrease pain and anxiety during rehabilitation, and enhance rehabilitation outcome. In a novel application of existing technology, an interactive CD-ROM will be developed to provide ACL reconstruction patients with information on surgery- and rehabilitation-related matters and instruction in presurgical and postsurgical coping strategies. Audiotapes based on an empirically validated relaxation and guided imagery protocol for postsurgical ACL rehabilitation will also be produced. Phase I tasks will include: (a) developing content for the CDROM; (b) examining the accuracy and usability of the content generated for the CDROM; (c) producing initial prototypes of the CD-ROM and audiotapes; (d) evaluating the acceptability, usability and potential utility of the prototype multimedia package with the target population; and (e) finalizing plans to produce a revised prototype of the multimedia package, and evaluate its effect on presurgical and postsurgical processes and outcomes in Phase II.

Project Title: BIOMECHANICAL ANALYSIS IN STRABISMUS SURGERY Principal Investigator & Institution: Demer, Joseph L.; Professor; Jules Stein Eye Institute; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, CA 90024 Timing: Fiscal Year 2001; Project Start 06-JAN-1991; Project End 31-DEC-2005 Summary: (Adapted from applicant's abstract): Strabismus, the misalignment of the eyes, is prevalent in the US and usually treated surgically with imperfect results. This is the predictable result of an inadequate paradigm for understanding orbital anatomy and the biomechanics of binocular alignment, sometimes leading to erroneous diagnoses and surgery. The overall aim of this project is to develop a physiologically realistic, quantitative understanding of the biomechanics of the extraocular muscles (EOMS) and associated connective tissues responsible for the movement and alignment of the eyes, and to apply this information to the diagnosis and treatment of strabismus. Recent evidence in humans and other primates shows that orbital connective tissues form a complex gimbal system to regulate ocular kinematics. The global layer of each rectus extraocular muscle (EOM) rotates the eye, while the orbital layer of that EOM translates the connective tissue pulley that serves as the EOM's functional origin. Pulleys play a crucial role in normal biomechanical alignment. Congenital and acquired abnormalities of pulleys cause some types of pattern strabismus, and others may be related to manipulations of pulley tissues during strabismus surgery. We propose a multidisciplinary approach to understanding the mechanics of binocular alignment through parallel studies in humans and monkeys. We will employ magnetic resonance imaging (MRI) to obtain near-microscopic resolution of EOMs and connective tissues as they change with the direction of gaze in normal and strabismic subjects. We will test "the active pulley hypothesis" that the dynamic translational position of normal pulleys is regulated to be consistent with ocular kinematic behavior such as Listing's Law of ocular torsion. We will study EOM pulleys in normal aging, where characteristic forms of strabismus become prevalent. Comparison of orbital imaging in congenital and acquired cyclovertical strabismus will provide evidence concerning the causal
Studies 13
relationship between pulley heterotopy and strabismus. We will investigate the possible relationship between pulley abnormalities and two common co-morbidities of esotropia, dissociated vertical deviation and inferior oblique overaction. We will investigate in humans the effects of aging and other pathology on EOM connective tissue structure and constituents, and behaviorally and anatomically define the relationship of EOM proprioceptive organs to pulleys. We will compare pulleys in normal monkeys with those who are naturally and artificially strabismic. Data will be tested in computational models of binocular alignment suitable for clinical use. Findings will critically evaluate a new and potentially more useful paradigm for the understanding of ocular motility and treatment of strabismus.

Project Title: BONY EFFECTS OF TRANSIENT NONSKELETAL ILLNESS Principal Investigator & Institution: Heaney, Robert P.; John A. Creighton University Professor; None; Creighton University 2500 California St Omaha, NE 68178 Timing: Fiscal Year 2001; Project Start 15-AUG-1998; Project End 31-JUL-2004 Summary: (Adapted from the Applicant's Abstract): This project seeks to quantify the extent and time course of the bone loss produced by episodes of temporary illness of a sort associated with bed rest and catabolic influences. The underlying hypothesis is that recovery of bone lost under these circumstances is often incomplete, particularly in critical regions such as the spine and hip. If true, this would mean that some portion of age-related bone loss is a punctuated phenomenon, related to illness and/or immobilization, rather than being continuous and inexorable. This finding would open up additional opportunities for osteoporosis prevention. As a surrogate for a wide variety of catabolic episodes, the investigators will use routine, elective abdominal or pelvic surgery performed on individuals 55-70 years of age. They will measure bone mass by DEXA at spine and hip in 150 individuals before surgery, at 4-8 weeks post surgery, and then at 4, 8, and 12 months, to quantify and characterize the extent of bone lost under these circumstances. They will also measure various potentially modifying covariates, such as degree of temporary disability, Ca intake, hormonal therapy, vitamin D status, age, and life-style factors, any of which might plausibly influence extent of bone loss or degree of recovery. They will compare decreases at various time points after surgery to baseline values in each woman and will compare mean bone mass changes at 12 months with a non-operated control group matched for age and estrogen replacement therapy and measured twice across a 12-month interval.

Project Title: CARPAL TUNNEL SYNDROME: DIAGNOSTIC AND TREATMENT STRATEGIES Principal Investigator & Institution: Jarvik, Jeffrey G.; Professor; University of Washington Seattle, WA 98195 Timing: Fiscal Year 2002; Project Start 15-FEB-2002; Project End 31-DEC-2006 Summary: (provided by applicant): While there is good evidence that patients with severe carpal tunnel syndrome (CTS) benefit from surgery, there is less evidence of a benefit for patients with mild to moderate disease. However, mild to moderate disease still accounts for important disability. Electrodiagnostic studies (EDS) have not been shown to accurately predict outcomes for patients with CTS. Recent advances in magnetic resonance (MR) permit high-resolution neurographic imaging of the median net-ve and pilot data suggest that MR neurographic imaging (MRNI) might be a better
14 Surgery
predictor of outcome than EDS. Thus, MRNI has the potential for playing a major role in the treatment of patients with CTS. We will test more hypotheses 1) that select patients with early, mild or moderate CTS benefit more from early surgery than with conservative therapy, and: 2) that MRNI accurately, identifies those patients more likely to benefit from early surgery. To test our hypotheses, we will recruit 500 patients with early, mild or moderate clinical CTS. After enrollment, patients will complete a standardized hand examination, EDS, symptom and functional status questionnaires, and a baseline high-resolution wrist MRNI. All patients will be treated for 2 weeks with standardized, optimal non-surgical therapy. Patients who improve within 2 weeks will be followed for I year. Patients who do not improve will be offered enrollment in trial in which they will be randomly assigned to either surgery or non-surgical therapy. We expect to randomize 200 subjects. We will offer to those patients who are randomized to non-surgical therapy an optimized, standardized hand therapy protocol, pharmaceutical and psychological intervention. We will offer localized ultrasound treatment to those who fail to improve after 3 months and surgery to patients who still have failed to improve after 6 months. The primary outcome measure will be the Carpal Tunnel Syndrome Assessment Questionnaire (CTSAQ) functional status index at 12 months. Our study design will allow us to determine if there are patients who benefit from early carpal runnel release and whether MRNI accurately identifies them.

Project Title: CASPASE INHIBITION OF APOPTOSIS, INFANT CARDIAC SURGERY Principal Investigator & Institution: Mcgowan, Francis X.; Associate Professor; Children's Hospital (Boston) Boston, MA 021155737 Timing: Fiscal Year 2001; Project Start 01-JAN-2001; Project End 31-DEC-2005 Summary: (Verbatim from Applicant's Abstract): A major limitation to successful outcome of the repair of congenital heart lesions is the development of ventricular dysfunction. While the etiology is undoubtedly multifactorial, evidence suggests that it in large part may be due to myocyte loss resulting from chronic cyanosis, prolonged exposure to abnormal hemodynamic loads, and one or more episodes of ischemiareperfusion required for cardiac surgery. Death of myocytes can occur by either necrosis or apoptosis. In contrast to necrosis, apoptosis is the orderlv disassemblv of the cell by specific enzymatic pathways that are triggered by a wide variety of genetic, environmental and toxic stimuli. Recently, human and animal studies have shown that hypoxia, ischemia-reperfusion, abnormal mechanical loading, and inflammation can cause significant cardiomyocyte apoptosis. This occurs during myocardial ischemia, infarction, hypertrophy, and heart failure. The role of apoptosis in infants undergoing cardiac surgery is not known. Based upon this information and preliminary data from our laboratory, we believe that myocyte apoptosis is a significant problem in infants with normal and hypertrophied myocardium subjected to surgical ischemiareperfusion. This loss of myocytes will be particularly injurious to the infant myocardium because of the loads imposed by future growth and residual hemodynamic abnormalities. Because the pathways triggering apoptosis in this setting are multiple, we have chosen to focus on the role of the caspase enzymes. Caspases are the focal point of propagation and execution of apoptosis, and are directly responsible for the proteolytic cleavage of specific proteins required for the process to occur. Experiments in Aim I will be the first to l)define which caspases are expressed, activated, and what key intracellular proteins are thereby cleaved in normal and hypertrophied myocardium exposed to surgical ischemia-repercusion, 2)quantify the amount of apoptosis that
Studies 15
occurs in this setting, and 3)determine the effects of specific caspase inhibition on these events. Using a novel working heart transplant model with normal and hypertrophied infant hearts, Aim II will answer a question of critical importance, namely what is the effect of inhibition of caspases and apoptosis on long-term myocardial inflammation, fibrosis, and recovery of function? These experiments will be the first to study the beneficial versus harmful roles of apoptosis in myocardial ischemia-reperfusion injury. Overall, these studies will provide valuable new insights into therapeutic targets and strategies to preserve myocardial function in these patients. The results are also likely to be applicable to patients with ischemia, myocardial infarction, and heart failure. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: CLINICAL APPLICATION OF IMAGE GUIDED LIVER SURGERY Principal Investigator & Institution: Chapman, William C.; Surgery; Vanderbilt University 3319 West End Ave. Nashville, TN 372036917 Timing: Fiscal Year 2002; Project Start 01-MAR-2002; Project End 31-MAY-2002 Summary: The surgical treatment of hepatic tumors is performed by removal or ablation of the involved tissue based on direct palpation and visual assessment sometimes aided with intraoperative ultrasound (IOUS). A new technology, interactive image-guided surgery (IIGS) displays current surgical positions on tomographic images (CT,MR,PET, etc) and permits the identification of precise working position with respect to previously identified anatomic and/or pathologic landmarks. Thus, the exact location in 3-D space can be shared and correlated throughout an operative procedure and significantly enhance surgical navigation. Engineering concepts and mathematical principles will be used in the development of an innovative IIGS system for hepatic surgery, including image processing for effective segmentation of the liver from abdominal CT scans, image registration to map physical space into image space, and integrated hardware and software development to create a system that can be used in th operating room. The specific aims of the R21 phase of this grant are: 1) Develop an automatic method for 3-D liver segmentation for accurate registration under image-guided hepatic surgery; 2) Develop techniques for track ultrasounds for specific use in image-guided hepatic surgery; 3) Adequately control hepatic motion and develop accurate registration algorithms incorporating liver surface data obtained in real-time with a laser scanner. The focus in the R33 phase of this grant will be on the clinical use of the system, with the eventual goal being image-guided ablation and resection of tumors. The specific aims proposed for years 2-4 of this project are: 1) Strengthen automatic methods for robust liver segmentation and surface registration during image-guided hepatic surgery; 2) Confirm system accuracy in tumor targeting using image-guidance in patients undergoing standard liver resection; 3) Determine th effectiveness of image-guided ablation in patients undergoing liver resection procedures; 4) Use image-guided ablation to accurately target and destroy primary and metastatic hepatic tumors and provide surgical navigation during hepatic resection. We believe that IIGS will significantly enhance currently performed clinical procedures and will permit accurate tumor localization for ablation and resection procedures. This technology also may permit minimally invasive treatment of liver tumors now performed in very limited circumstances. This work will also be carried out as a collaborative project between William Chapman, M.D. in the Department of Hepatobilliary Surgery and Liver Transplantation and Robert Galloway Ph.D., in the Department of Biomedical Engineering and other members within the center for Technology-Guided Therapy at Vanderbilt.

Project Title: COGNITIVE EFFECTS OF LUNG VOLUME REDUCTION SURGERY Principal Investigator & Institution: Kozora, Elizabeth; National Jewish Medical & Res Ctr and Research Center Denver, CO 80206 Timing: Fiscal Year 2001; Project Start 01-FEB-2000; Project End 31-JAN-2003 Summary: The primary goal of this study is to examine the neuropsychological functioning of emphysema patients undergoing lung volume reduction surgery (MT+LVRS) compared to medical therapy alone (MT). The study will include patients at two clinical sites for the National Emphysema Treatment Trial (NETT). Enhancements of ventilation and functional capacity are expected to contribute to greater long-term improvements in utilization of oxygen in the brain, thereby leading to improvements in cognitive performance greater than those observed among patients who exercise but do not receive LVRS (Specific Aim 1). A health control group will be retested on similar neuropsychological tests in order to control for practice effects (Specific Aim 2). Although we do not expect significant differences in emotional (depression and anxiety) functioning across groups, this study will enable us to evaluate the relationship between emotional status and neuropsychological scores in the MT+ LVRS and MT groups following randomization. In addition, since major neurological events are more likely following surgery, and major neurological events affect cognitive function, we will evaluate the incidence of neurological events in our sample and will determine the degree to which neurological events are associated with cognitive function (Specific Aim 3). No studies have examined the relationship between change in cognition and improve quality of life in COPD patients following LVRS surgery, therefore, we aim to explore these associations in Specific Aim 4. We propose to compare changes following LVRS and MT by examining 84 NETT patients (42 in MT, 42 in LVRS) at three times points (baseline, post 6-10 week medical treatment MT, and 6 months post MT or LVRS randomization) using select neuropsychological, psychological, neurological and QoL tests. Forty normal controls will be tested at baseline and 6-10 weeks follow- up. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: DECISIONS & OUTCOMES OF BRCA 1/2 TEST FOR BREAST PATIENT Principal Investigator & Institution: Schwartz, Marc D.; Co-Director; V T Lombardi Cancer Res Center; Georgetown University Washington, DC 20057 Timing: Fiscal Year 2001; Project Start 01-AUG-1997; Project End 31-MAY-2003 Summary: The investigators propose a prospective, longitudinal study to examine decision-making about pre-surgery BRCA1/2 testing and the medical, psychosocial, and economic outcomes of testing among newly-diagnosed breast cancer patients who are at high risk for having a BRCA1/2 mutation. The theoretical framework for this investigation is derived from Expected Utility Theory. The Specific aims are (1) to establish rates of uptake of the BRCA1/2 testing prior to surgical treatment for breast cancer and to identify the determinants of the decision to be tested; (2) to evaluate the impact of BRCA1/2 testing on patients' surgical treatment choices; (3) to evaluate the impact of pre-surgery BRTCA1/2 testing on psychological well-being; and (4) to develop a model to estimate the costs of BRCA1/2 testing for newly-diagnosed breast cancer patients per quality-adjusted life years saved. The subjects in this prospective longitudinal study are 400 newly diagnosed breast cancer patients who have an equal to or greater than 25 percent prior probability of having a BRCA1/2 mutation. A baseline assessment will be conducted prior to the offer of testing to collect data on background/controlling variables (sociodemographics, medical, physician and family
Studies 17
factors), predictor/moderator variables (preferences for health outcomes, coping style, anxiety, social support), and baseline levels of outcome variables (psychosocial well being, prevention and surveillance practices). Following pre-test education and informed consent, patients will have an opportunity to have BRCA1/2 testing and receive their result during an individual session with a genetic counselor. Follow-up interviews will be conducted at 1-, 6-, 12-, and 18-months post-surgery to collect outcome data. The primary group comparisons in multiple regression models will be between BRCA1/2 carriers, non carriers, and pre-surgery test decliners. The proposed cost-effectiveness analysis will incorporate prospective data on patient preferences and outcomes together with secondary data from the literature, into a decision-analytic model.

Project Title: DEVICE FOR PROMOTING SURVIVAL OF CONGESTED TISSUE FLAPS Principal Investigator & Institution: Conforti, Michael L.; Spectro Con 2701 Van Hise Ave, Ste Fc Madison, WI 53705 Timing: Fiscal Year 2002; Project Start 01-FEB-2002; Project End 31-JUL-2002 Summary: (provided by applicant): New technology is needed for the treatment of venous congestion, a serious complication of reconstructive surgery. Currently, live leeches are used, but are psychologically traumatic to patients being treated, and are often ineffective in preventing tissue death. Because there are no other alternatives for treating venous congestion, a mechanical device for this purpose represents a pioneering concept, unique to the current marketplace. The long-term goal of this research is to develop a fully automated, clinically applicable medical device capable of treating venous congestion over an extended time period. The aim of Phase I is to demonstrate feasibility of using a rudimentary device prototype developed in our laboratory to successfully treat venous congestion for a 12-hour period. Congested fasciocutaneous pedicle flaps will be created in 16 pigs, with 8 treatment and 8 control animals. Tissue health during treatment and control experiments will be monitored by quantitative measurements of skin color, surface perfusion, subcutaneous oxygen tension, and blood volume removed. Histological analysis of tissue viability at the end of 12 hours will determine the success of the device in treating venous congestion. A device that effectively treats venous congestion will replace the use of live leeches and will have far-reaching societal benefits. PROPOSED COMMERCIAL APPLICATIONS: The innovative technology developed will completely replace medicinal leeches as the standard treatment for venous congestion, a serious complication of reconstructive surgery.

prior to their acceptance as treatment modalities of choice for oral cancer patients. The investigators outline a longitudinal study to test three hypotheses: (1) the conventional dental prosthesis restores specified oral functions and perceptions to the pre-cancer levels; (2) the implant-supported dental prosthesis restores oral functions and oral perceptions to the pre-cancer surgery levels; and (3) the conventional denture and implant-supported prostheses are equally efficient in restoring specified oral functions and perceptions. A total of 62 patients with early oral cancer will be recruited; in addition, 22 patients requiring a partial maxillectomy and 40 requiring a partial lateral mandibulectomy will be enrolled. The mandibular defects will be reconstructed with fibula free flap surgery. Following a healing period, implants will be placed and permitted to heal unloaded for six months. Conventional dental prostheses will be fabricated and used by patients for at least 16 weeks during Phase I healing before the implants are exposed and loaded. A few weeks after Phase II surgery, the patients will receive implant-supported dental prostheses. A complete series of oral functional tests and questionnaires will be administered at four time intervals: (1) prior to ablative surgery; (2) one week before insertion of conventional denture prostheses; (3) 16 weeks after conventional dental prostheses insertion; and (4) 16 weeks after implant-supported dental prostheses insertion. All patients will be followed at 6 month intervals, for 12-36 months, to establish implant success rates, using life table analysis.

Project Title: ENDOTHELIAL DYSFUNCTION AND PERIOPERATIVE EVENTS Principal Investigator & Institution: Gokce, Noyan; Boston Medical Center Gambro Bldg, 2Nd Fl, 660 Harrison Ave, Ste a Boston, MA 02118 Timing: Fiscal Year 2001; Project Start 01-SEP-2000; Project End 31-JUL-2005 Summary: The overall goal of this application is to provide support and training for the applicant towards becoming an independent, patient-oriented clinical investigator in the field of vascular biology. The proposed application builds on the applicant's previous research experience, provides new training, and examines a highly relevant clinical question conducted in a mentor-based environment ideally suited for the completion of this project. The overall objective of the proposed plan is to investigate the importance of examining endothelial function as a predictor of cardiovascular events in patients with atherosclerotic vascular disease. The vascular endothelium regulates vasomotor tone, platelet activity, and inflammation through the synthesis and elaboration of a number of factors including endothelium-derived nitric oxide (EDNO). Endotheliumdependent vasodilation and platelet inhibition are impaired in atherosclerosis and associated conditions, possibly due to increased vascular oxidative stress and reduced NO bioactivity. Loss of normal vascular endothelial function favors a local vasospastic, prothrombotic, and proinflammatory milieu, and is linked to the pathophysiology of cardiovascular events including myocardial infarction, stroke, and unstable angina. However, no study to date has demonstrated that impaired endothelial function is predictive of cardiovascular risk. Patients with peripheral arteriosclerotic disease undergoing vascular surgery have multiple risk factors for endothelial dysfunction, and are at high-risk for perioperative cardiovascular events. Using non- invasive, highresolution vascular ultrasound analysis of brachial arterial vasomotor function, this project proposes in specific aim 1: to determine whether patients with impaired preoperative vascular endothelial function have increased cardiovascular events at the time of vascular surgery compared to patients with normal endothelial function, and in specific aim 2: to determine whether pretreatment of subjects with impaired endothelial function using the antioxidant ascorbic acid (Vitamin C) reduces perioperative

Project Title: EPIDEMIOLOGY OF LUMBAR SPINE SURGERY: RATES AND TRENDS Principal Investigator & Institution: Deyo, Richard A.; Professor; University of Washington Seattle, WA 98195 Timing: Fiscal Year 2002; Project Start 15-FEB-2002; Project End 31-DEC-2006 Summary: (provided by applicant): Spine surgery rates in the United States exceed those in most developed countries by at least twofold. Furthermore, they increased 55 % during the 1980's. Wide geographic variations in surgical rates may imply professional uncertainty about optimal indications. Recent technical changes in spine surgery, including new spinal implants and a shift towards ambulatory surgery, may affect surgical rates and reoperation rates. The goals of this project are to examine whether surgical rates continue to rise, and if the introduction of interbody fusion cages resulted in acceleration of surgery rates: to examine surgical rates among the elderly and for spinal stenosis in particular to examine whether reoperation rates are increasing over time; and to determine if certain surgical procedures are associated with unusually high rates of reoperation. The analyses will make use of existing survey and administrative data. We will use a previously validated algorithm for identifying patients with lumbar spine surgery from automated data, as well as a previously validated comorbidity index. National rates of surgery will be examined using the National Hospital Discharge Survey and the Healthcare Cost and Utilization Project, both available from the National Technical Information Service, Examination of rates and trends among elderly patients, and especially for spinal stenosis, will make use of these national databases and of Medicare claims data for selected years. The analysis of reoperation rates will depend largely on a Washington State hospital discharge registry which will provide data from 1987 through 2000. Reoperation rates will also be examined using Medicare claims data. Finally, we hope to examine the growth of ambulatory disc surgery, which became increasingly popular after 1994. Although previously available surveys of ambulatory surgery are no longer available, we will have an opportunity to examine the growth of the ambulatory surgery using Medicare claims data, and some state ambulatory surgery databases. This series of analyses is important because it will help to clarify factors associated with changes in surgical rates. It will also help to assess the impacts of recent technical and practice innovations. Reoperation is generally regarded as an unfavorable outcome of lumbar spine surgery, and rising reoperation rates would be alarming. Thus, rates and trends in the use of spinal surgery and repeat operations may help identify high priorities for research, suggest areas requiring a more consistent therapeutic approach, and indicate possible problems in quality of care.

Project Title: ESTRADIOL FOR NEUROCOGNITIVE DYSFUNCTION AFTER CABG Principal Investigator & Institution: Hogue, Charles W.; Anesthesiology; Washington University Lindell and Skinker Blvd St. Louis, MO 63130 Timing: Fiscal Year 2001; Project Start 01-JUN-2001; Project End 31-MAY-2006
20 Surgery
Summary: Women undergoing coronary artery bypass graft (CABG) surgery have a higher operative mortality rate, longer hospitalizations, and higher hospital cost compared with men. A large proportion of this excess morbidity and mortality of surgery for women is due to perioperative neurologic injury. Estrogens have been consistently shown to reduce the extent of neurologic injury in a variety of in vitro and animal experimental stroke models. These data together strongly suggest that the higher risk for perioperative neurologic complications for elderly women may relate to their estrogen deficient state. In this randomized, placebo controlled study, we will test the hypothesis that perioperative estrogen replacement in postmenopausal women reduces the risk for neurologic injury after CABG surgery. Three hundred thirty four women undergoing CABG surgery will be prospectively randomized to receive either 17betaestradiol or placebo in a double-blind fashion beginning the day before surgery and continued for 5 days after surgery. Patients will be assessed for neurocognitive dysfunction, the most common manifestation of neurologic injury from cardiac surgery. Neurocognitive testing will be performed 1-2 days before surgery, 4 to 6 weeks postoperatively, and 6- months after surgery. The primary endpoint will be neurocognitive function 4 to 6 weeks after surgery for women who received 17betaestradiol compared with placebo perioperatively. We will also evaluate for the importance of postoperative cognitive decline on measures of cognitive function and quality of life 6 months after surgery and whether perioperative 17beta-estradiol treatment improves these latter outcomes. The results of this study will evaluate the efficacy and safety of an easily implemented therapy for improving neurologic outcome and quality of life after CABG surgery for postmenopausal women.

Project Title: FEEDING BEHAVIORS & ENERGY COST IN INFANTS WITH CHD Principal Investigator & Institution: Medoff-Cooper, Barbara S.; Professor and Director of Center for Nur; None; University of Pennsylvania 3451 Walnut Street Philadelphia, PA 19104 Timing: Fiscal Year 2002; Project Start 01-JUN-1994; Project End 31-MAY-2007 Summary: (provided by applicant) This proposal requests continued support for a NINR funded study that had been entitled: Nutritive sucking: Physiological and Behavioral correlates. In the present proposal, we (1) deepen our analysis of feeding organization by integrating measures of sucking, swallowing and breathing over the course of full meals and (2) characterize the feeding patterns of another at-risk population - infants with congenital heart disease (CHD), and (3) relate feeding performance and energy expenditure to problems in growth and development over the first year of life in CHD infants. These infants are often difficult to feel, even when their surgery has improved their cardiac function. Indeed, the success of the surgery often unmasks their severe nutritional syndrome, failure to thrive (FTT). To address this important clinical problem, we propose to measure feeding performance and energy expenditures over the first hear of life in 120 infants who have undergone surgery during the first month of life to correct or palliate sever cardiac abnormalities and 60 healthy newborn controls. The specific aims of our proposed study are as follows: 1) to establish which aspects of feeding performance (e.g. suck/swallow/breathe coordination, temporal patterning of sucking with meals, suck pressure generation, adaptation to variation in flow rate) are most subject to disruption in CHD infant after corrective or palliative surgery; 2) to determine infants' pattern of oropharyngeal adaptation to variations in the flow rate through an artificial nipple, and whether flow rate adjustment represents a viable strategy for improving meal size outcomes; and 3) to determine the relative contributions of disrupted feeding organization and (potentially elevated) energy expenditure to unfavorable growth outcomes, i.e. (i) relate disrupted feeding to growth, (ii) relate energy expenditure to growth, and (iii) integrate energetic and feeding-performance characteristics in a predictive model of failure to thrive in infants with CHD. This study addresses what we believe is the central role of feeding organization in the nutritional status of this patient population; as such, it represents an approach toward early identification, based on feeding performance and energetic profiles, of infants most at risk for developing FTT by the age of one. The present work may offer prospects for targeted behavioral interventions involving modification of flow rates and paced feeds. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: FUNCTIONAL MRI FOR NEUROSURGICAL PLANNING IN EPILEPSY Principal Investigator & Institution: Constable, Robert T.; Diagnostic Radiology; Yale University 47 College Street, Suite 203 New Haven, CT 065208047
22 Surgery
Timing: Fiscal Year 2002; Project Start 01-APR-1999; Project End 31-MAR-2007 Description (provided by applicant): Epilepsy patients who are candidates for surgical resection of a brain lesion must have some form of functional mapping to determine if the lesion can be removed without creating a functional deficit. The current procedures for mapping language in these patients are spatially limited (e.g. hemispheric mapping with Wada testing) or highly invasive (cortical stimulation using subdural electrodes). Functional MR imaging (fMRI) has the potential to replace, or significantly enhance, the current methods used in Neurosurgical planning. It is noninvasive and has been shown to be able to localize cortical activity. However, the standard echo planar imaging fMR1 methods, based on the BOLD activation response, suffer from low spatial resolution, and sensitivity to static Bo magnetic field inhomogeneities which lead to image distortions and low signal intensity. These problems severely limit the ability of fMRI to localize brain activity for Neurosurgical planning. This project has 3 aims. First, it is designed to improve fMRI methodology. Our earlier work has identified the need to develop single shot approaches to maximize statistical power in fMRI studies, and thus the methodology developments will focus on single shot approaches to image distortion and signal loss, including the investigation of asymmetric spin echo EPI and dynamic shimming. This innovative program will allow for highly robust functional localization required for surgical planning, but the methods to be developed may be applied to any fMRI study. Secondly, we will continue our work on validating the fMRI activation detected through comparison with Wada testing and cortical stimulation. A battery of fMRI language paradigms, parallel to out-of-magnet behavioral studies, have been designed to address the specific deficits obtained in temporal lobe epilepsy patients and these will be applied to both control subjects and patients with intractable epilepsy who are candidates for surgery. Patients will be imaged and tested behaviorally both pre and post- surgery. Through such studies the ability of fMRI to predict surgical outcome will be evaluated. Finally, we will examine the relationship between disease states (mesial temporal sclerosis, cortical malformations, and tumors) and language reorganization both acutely (pre- and post- surgery) and chronically by relating the language organization and performance prior to surgery, to the type, location, and age at onset of epilepsy. Such a study will provide evidence not only of language reorganization but also of the specific cortical regions that reorganize, and the impact this reorganization has on performance and surgical outcome.

&
POST-OP
COGNITIVE
Principal Investigator & Institution: Newman, Mark J.; Vice President; Anesthesiology; Duke University Durham, NC 27706 Timing: Fiscal Year 2001; Project Start 30-SEP-1999; Project End 31-JUL-2004 Summary: Our investigative team has recently discovered a genetic association between late-onset Alzheimer's disease and the apolipoprotein E (APOE, gene; apoE, protein) epsilon-4 gene. This finding has triggered many recent studies showing an important role of apoE in the determination of neurologic injury and recovery following a variety of acute ischemic insults including intracerebral hemorrhage, closed head injury, acute stroke and dementia pugilistica (chronic traumatic brain injury). An important aspect of our work is the finding of an association between APOE4 and neurocognitive decline after cardiac surgery. Although mounting evidence suggests apoE plays a role in acute and chronic neurological disease, the mechanism underlying these observations and the influence of aging is not completely understood. We hypothesize that a genetic
Studies 23
predisposition exists for the easily documented neurologic and neurocognitive dysfunction observed after anesthesia and surgery. ApoE may play a role in modulating the inflammatory response to ischemia and perioperative stress. We have recently determined that ApoE, in vivo, modulates the release of nitric oxide and TNF-alpha in glial cells. This may compound the autonomic dysregulation that we recently reported in the elderly. The combination of these two factors may modulate an exaggerated inflammatory response increasing the susceptibility to perioperative injury. Our pilot data associating APOE4 with cognitive impairment after cardiac surgery support this hypothesis. Therefore, we propose to determine the association between post-operative neurocognitive dysfunction, neurocognitive recovery, and APOE4 genotype in patients undergoing thoracic and vascular surgery. The unifying hypothesis is that a genetic susceptibility to neurologic dysfunction after surgery results either from a predisposition to immunologic dysregulation, the failure of normal genetically encoded reparative processes, or a combination of these mechanisms resulting in a greater incidence and severity of neurocognitive dysfunction and reduction in quality of life and independence in the aging population after surgery. Thus, our extensive preliminary work as well as our expanded collaborative interdisciplinary research group including cardiac anesthesiologists, cardiac surgeons, neuroscientists, geneticists and neurologists is uniquely able to investigate the genetic predisposition to neurocognitive dysfunction after surgery. Such an association is an important first step in elucidating the mechanism underlying genetic susceptibility to ischemic insults, and designing interventional strategies to improve outcome.

Project Title: GUT ISCHEMIA/REPERFUSION INJURY: MODULATION BY NUTRIENTS Principal Investigator & Institution: Kozar, Rosemary A.; Surgery; University of Texas Hlth Sci Ctr Houston Box 20036 Houston, TX 77225 Timing: Fiscal Year 2002; Project Start 10-AUG-2002; Project End 31-JUL-2007 Summary: (provided by applicant): Candidate: Dr. Kozar is a new faculty member at the University of Texas-Houston Medical School (UTHMS), where she is a member of the Department of Surgery. She first acquired basic research skills as a NRSA Fellow while obtaining her PhD at Baylor College of Medicine. Following completion of her general surgery training, the candidate accepted a faculty position in Trauma and Critical Care at MCP-Hahnemann University School of Medicine under the direction of Dr. Joel Rosyln. During this time she began to develop research experience in the field of Trauma and Critical Care by investigating the activity of antioxidant enzymes in an acute lung injury model, funded by a private grant for which she was the principal investigator. Since becoming a faculty member in the Department of Surgery at UTHMS she has become very active in the NIGMS-sponsored Trauma Research Center, focusing on the role of the gut in multiple organ failure. A Career Development Award, in conjunction with the support of two highly respected mentors, would enhance the acquisition of the necessary skills and talents crucial to becoming a future independent investigator. Research: The proposed research project is an extension of the Trauma Research Center?s interest in the link between gut dysfunction and multiple organ failure. As proposed in this application, the candidate wilt test the hypothesis that specific enterat nutrients during gut ischemia/reperfusion impair gut function and enhance gut injury. The goal of the proposed project is to understand how enterat nutrients during times of metabolic stress can be detrimental to gut function. The results obtained will facilitate a better understanding of postinjury gut dysfunction and aide in
24 Surgery
future strategies to achieve enteral tolerance in patients at high risk for multiple organ failure. Environment: The UTHMS in the center of the Texas Medical Center is comprised of 42 member institutions dedicated not only to outstanding patient care but also to the highest standards and quality of research. As part of the Department of Surgery's Trauma Research Center, the candidate has the guidance and support of numerous researchers in the Department of Surgery as well as in Integrative Biology, and Medicine. The sponsors are an integral part of this arrangement and are especially suited to ensure success of the proposed project. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: HAPTIC FEEDBACK FOR ROBOT-ASSISTED SURGICAL SYSTEMS Principal Investigator & Institution: Okamura, Allison M.; Mechanical Engineering; Johns Hopkins University 3400 N Charles St Baltimore, MD 21218 Timing: Fiscal Year 2003; Project Start 30-SEP-2003; Project End 31-JUL-2007 Summary: (provided by applicant): Cardiac surgery is traditionally performed through a median sternotomy, providing optimal access to all cardiac structures and great vessels, but generating significant disfigurement and pain for the patient. The advent of robot-assisted minimally invasive surgery (MIS) holds great promise for improving the accuracy and dexterity of a surgeon while minimizing trauma to the patient. However, clinical success with robot-assisted cardiac MIS has been marginal; improved patlent outcomes and mitigated costs have not been proven. We hypothesize that this is due in large part to the lack of haptic feedback presented to the surgeon. Without the sense of touch naturally used in surgical tasks such as fine suture manipulation, surgeon performance is jeopardized. The general objective of the proposed research is to acquire and use haptic information during robot-assisted minimally invasive surgery, with a focus on manipulation of fine sutures. It is anticipated that this approach will offer two main benefits over current systems: (1) forces will be fed back to the user in real time, directly or through sensory substitution, improving task performance, and (2) haptic information will be used to create automatic virtual fixtures that assist the surgeon, e.g., by prevention of excessive applied suture forces and maintenance of constant retraction forces. The specific aims are: (1) to understand the sensing requirements for minimally invasive surgical tasks, (2) to test different modes of haptic feedback in robot-assisted minimally invasive surgical environment, (3) to create virtual fixtures that augment and improve the execution of surgical tasks, and (4) to apply feedback of haptic information during phantom experiments, creating a direct path to clinical applications. These specific aims contribute to a Iong-term research plan for using haptic information in robot-assisted minimally invasive surgery. The proposed work represents the development of operative technology that can provide significant improvements in patient outcomes, as well as Iay the groundwork necessary to address several other exciting research issues such as beating-heart (off-pump) procedures, procedure and tissue models, and virtual environments for training.

Project Title: HIGH INTENSITY ULTRASOUND FOR NON-INVASIVE SURGERY Principal Investigator & Institution: Cain, Charles A.; Chair; Bioengineering; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, MI 481091274 Timing: Fiscal Year 2001; Project Start 01-APR-2000; Project End 31-MAR-2005 Summary: (Adapted from Applicant's Abstract): Check thisWays to make acoustic cavitation predictable, and thus practical as a mechanism for noninvasive surgery, will
Studies 25
be explored in this research. Novel ways to accurately place therapy beams and verifying that surgical lesions have been formed will also be explored. With the use of large aperture phased array systems, and aberration correction techniques, it is possible to form high quality ultrasound beams around and through obstructions like ribs, or the skull, with the attractive possibility of noninvasive brain surgery or cardiac ablation for treatment of life threatening arrhythmias. With the loss of energy in propagating around and through such obstructions, thermal ablation, without heating the complex intervening tissue, is a difficult proposition. However, cavitation, particularly from arrays operating at lower ultrasound frequencies, becomes an exciting tissue ablation mechanism for further study. Of particular interest is the potential use of stabilized microbubbles, often used as ultrasound imaging contrast agents, to act as cavitation nuclei lowering cavitation thresholds and making spatial localization predictable. Cavitation has been intentionally avoided in the past because reproducible localization of ablation zones (or surgical lesions) has been difficult mostly due to large unpredictable spatial variations in cavitation thresholds in living tissues. Preliminary experiments with phased array systems suggest that surgical lesion size and shape become more predictable with prior administration of contrast agents. The applicants proposed to systematically explore the role of contrast agents on cavitation thresholds, surgical lesion size and histology, predictability of shape and spatial localization of necrotic zones, and role of contrast agent concentration. Such systems will allow highly predictable beams to be formed non-invasively, for example, around the ribs onto a moving target, e.g. the heart. Contrast agents will also be explored as means for targeting therapy beams and as a way to verify that surgical lesions have been formed in the desired treatment volume. This application is based on their experimental observation that microbubbles can be "collapsed" by low intensity ultrasound causing "darker" areas in the image, thus allowing sub-lesion forming intensities to be used for beam localization prior to application of surgical intensities. Since cavitationally induced lesions will likely destroy the local vasculature, a surgically necrosed volume will not reperfuse with contrast agent indicating lesion extent. The applicants will explore use of contrast agents as means to guide, enhance, and verify surgical lesion formation with high intensity ultrasound.

Project Title: HIGH TEMPERATURE ULTRASOUND THERAPY GUIDED BY MRI Principal Investigator & Institution: Hynynen, Kullervo H.; Associate Professor; Brigham and Women's Hospital 75 Francis Street Boston, MA 02115 Timing: Fiscal Year 2001; Project Start 01-JUL-1988; Project End 31-MAR-2003 Summary: Surgical resection of secondary liver tumors has been shown to be an effective treatment in some patients with five year survival between 20-30 percent. Unfortunately, the surgery has a relatively high complication rate with 35 percent of patients suffering minor complications. About 15 percent suffer more serious complications with a mortality rate of 2-5 percent. In addition the average hospital stay is about two weeks without complications. Deep noninvasive coagulation of liver tumors could potentially eliminate some of these disadvantages of liver surgery. Most notably it could be feasible to eliminate infections and perform the procedure with short or no hospital stay. This could translate in to large cost savings and perhaps extend the therapy to patients who would not be eligible for major surgery due to other health reasons. During the current grant period we developed ultrasound phased array systems, and magnetic resonance temperature monitoring techniques that could be used for liver surgery. We have developed a 512 channel driving system for the phased
26 Surgery
arrays, theoretically designed and experimentally tested different array configurations, and developed array manufacturing techniques for magnetic resonance (MR) scanner compatible large scale arrays. We constructed a large scale array to demonstrate the feasibility of the proposed technique. Finally, we have shown that the temperature elevation induced during high power sonications in tissue can be quantified using MR temperature imaging. Now we propose to use our experience and hardware for the development of a noninvasive surgery technique for clinical liver tumor treatments. To reach this goal several basic ultrasound arrays and beam propagation concepts still need to be investigated prior to our ability to accurately execute noninvasive liver surgery. These will include theoretically optimizing the large scale array design for liver treatments, testing the designed arrays, and developing and testing ultrasound propagation models that take into account nonlinear propagation, tissue temperature elevation, and tissue changes due to thermal exposures. These theoretical models are required for accurate multi focal pattern sonication planning and control of the treatments. In addition the procedures for clinical liver treatments need to be developed and tested. Finally, we plan to investigate the potential of using ultrasound induced vascular occlusion for cancer therapy. In conclusion, during the current grant period we developed the basic tools that will make accurate noninvasive coagulation of liver tumors possible. During the next phase of this grant we plan to complete all of the required research so that the therapy can be tested in clinical treatments. The noninvasive focused ultrasound coagulation of liver tumors has a large clinical potential in reducing complication rates and costs associated with open surgery.

Project Title: HOST RESPONSE TO POST-OPERATIVE PNEUMONIA Principal Investigator & Institution: Knight, Paul R.; Professor and Vice Chairman; Anesthesiology; State University of New York at Buffalo 402 Crofts Hall Buffalo, NY 14260 Timing: Fiscal Year 2001; Project Start 01-JUL-2001; Project End 31-MAY-2006 Summary: (Verbatim from the Applicant's Abstract): Anesthesia/surgery predisposes the patient to develop nosocomial pneumonia by mechanisms that are not completely defined. The presence of a viral respiratory tract infection (RTI) during anesthesia/surgery further complicates the host antibacterial response. Evidence from our laboratory has demonstrated anesthesia/surgery induces changes in cytokine response (e.g., TNFalpha, MIP-2, IFNgamma), leukocyte recruitment, and lung injury to influenza RTI. These responses are also critical to innate host defenses against bacterial pathogens. Our focus is to examine cellular mechanisms during a viral RTI that predispose the host to a post-surgical bacterial pneumonia. We hypothesize that anesthesia/surgery will change host responses differently during distinct periods in the course of a viral RTI by altering expression of pro- and antiinflammatory cytokines, thereby decreasing antibacterial defenses. Aim #1 will assess the effects of anesthesia/surgery during influenza on bacterial clearance, inflammatory cell influx, and cytokine expression an Escherichia coli challenge. We predict that laparotomy during influenza will promote the relative expression of MCP-1 and IL-10 over TNFalpha, MIP-2, and IFNgamma. Aim #2: will assess ex vivo the combined effect of laparotomy and influenza on a) LPS stimulated aMphi cytokine expression and phagocytic activity, and b) the ability of in vitro antiMCP-1, antiIL-10, or IFNgamma administration to improve M dysfunction. We postulate that laparotomy during influenza will alter aMphi regulatory functions and decrease effector functions as a result of selective enhancement of expression anti-compared to proinflammatory
Studies 27
cytokines. Finally, in Aim #3, we will examine the contribution of endogenous cytokines in the suppression of antibacterial defenses following laparotomy during influenza by selective cytokine manipulations. Bacterial clearance, inflammatory cell influx, and cytokine levels will be assessed. We anticipate that neutralization of IL-10 or MCP-1, administration of IFNgamma, or increased TNFalphaexpression will improve antibacterial host defenses following laparotomy during physical signs of influenza. These studies will examine mechanisms that lead to alterations in bacterial clearance post-surgically following a viral RTI, assess the pathogenesis of post-surgical pneumonia in general, and suggest immune adjuvant strategies to prevent this complication.

Project Title: HYPOTHERMIA DURING INTRACRANIAL ANEURYSM SURGERY Principal Investigator & Institution: Todd, Michael M.; Anesthesia; University of Iowa Iowa City, IA 52242 Timing: Fiscal Year 2001; Project Start 05-SEP-1999; Project End 31-MAY-2004 Summary: Aneurysmal subarachnoid hemorrhage (SAH) remains a major cause of morbidity and mortality. Since the incidence peaks in mid-life, and since many survivors are permanently damaged, the human and economic costs are immense. Much of the death and disability is the acute and delayed result of blood in the subarachnoid space (e.g. vasospasm). However, an unknown - but we believe substantial - fraction of the adverse outcomes are a complication of surgery performed to obliterate the source of bleeding; as many as 25 percent of patients who undergo craniotomy for aneurysm clipping will have a new neurologic deficit when examined 12-24hrs postoperatively. This danger is well known, and almost all surgical teams utilize some method to protect patients during surgery, including barbiturates, etomidate, steroids, mannitol or varying degrees of hypothermia. Unfortunately, in spite of the popularity of such interventions, none has ever been systematically tested in humans (other than deep hypothermia and circulatory arrest), and none are known to provide any benefit at all. Of the aforementioned therapies, we believe the best laboratory evidence supports the use of hypothermia. Our goal, therefore, is to perform a prospective, randomized clinical trial to evaluate the safety and efficacy of intraoperative hypothermia (t=33 degrees C) as a means of reducing early and long-term postoperative neurologic morbidity following surgery for clipping of intracranial aneurysm. Control patients will remain normothermic during and after surgery; in hypothermic patients, body temperature will be normalized as quickly as possible after the aneurysm clip is in place. All other aspects of pre- and postoperative care will be managed routinely. We hypothesize that hypothermia, even when limited to the intraoperative period, will result in an improvement in neurologic outcome as measured by Glasgow Outcome Scale at 3months following surgery, and will also result in more rapid improvement during the first postoperative week.

Project Title: IMAGING THE VASCULAR RESPONSE TO IMPLANTS Principal Investigator & Institution: Barton, Jennifer K.; Assistant Professor; None; University of Arizona P O Box 3308 Tucson, AZ 857223308 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2007 Summary: (provided by applicant) Many commonly used implant materials elicit a strong foreign body response, leading to the encapsulation and failure of the implant. A
28 Surgery
preferred healing response involves a minimal inflammatory response and ingrowth of blood vessels. Currently, normal practice for evaluating novel implants involves surgically implanting devices in experimental animals, harvesting implants at various time points, and performing histological evaluation. The overall goal of this project is to identify the role that blood vessels serve in the healing response of an implant, through non-destructive optical imaging. Optical coherence tomography (OCT) and confocal microscopy will provide a greatly increased amount of data for the same number of implantations performed, and will allow a single implant to be followed for multiple weeks, mitigating concerns about animal-to-animal and surgery-to-surgery variations. As a long-term clinical goal, noninvasive imaging may allow identification of the earliest vascular response to the implant and prediction of its success. There are three specific aims associated with this application: Specific Aim 1. Evaluate the vascular response in glaucoma implant healing. Glaucoma implants offer an optically accessible model for implant healing. Both commercially available (Ahmed) and experimental expanded polytetrafluroethylene (ePTFE) implants will be placed in rabbit eyes with or without patches of ePTFE, pericardium or a scaffold-based three-dimensional human fibroblast culture. Time sequences of images will be acquired to determine the timing and degree of vascularization of the implants. Specific Aim 2. Evaluate the healing of vascular implants. Intra- and extra-vascular OCT imaging will be performed of stents and grafts placed in the peripheral arteries of large animals. The proper functioning of the implant and adverse reactions such as neointimal hyperplasia will be measured. Blood flow shear rate measurements will be made at the boundaries of the implant and native artery. Evaluation of the vascularization of grafts by small capillaries will be performed. Specific Aim 3. Expand OCT imaging capabilities through hardware and software developments. This aim includes developing miniature probes for intravascular and external use, increasing acquisition speed, and performing signal and image processing to measure perfusion, shear rate, and tissue image texture.

Project Title: INTRA-OPERATIVE CONFOCAL IMAGING-GUIDED MOHS SURGERY Principal Investigator & Institution: Rajadhyaksha, Milind M.; Ctr for Subsurface Sensing & Imaging Systems; Northeastern University 360 Huntington Ave Boston, MA 02115 Timing: Fiscal Year 2003; Project Start 20-SEP-2003; Project End 31-JUL-2007 Summary: (provided by applicant): The goal of this proposal is to develop and clinically test a real-time optical imaging modality based on confocal reflectance microscopy, with enhancement of nuclear-to-dermal contrast using acetic acid and crossed polarization, to intra-operatively examine basal cell cancers to guide Mohs micrographic surgery. Basal cell cancers (BCCs) are among the fastest growing cancers (>1.2 million new USA cases/year); because they occur most frequently on older people and in high risk anatomical sites (near or on the eyes, mouth, nose, ears), precise microsurgery is necessary with minimum damage to the surrounding normal tissue. Mohs surgery is time-consuming (one to several hours) and tedious because several (2-20) excisions must be made, and frozen histology sections carefully prepared and examined for each. Realtime confocal reflectance imaging may make Mohs surgery significantly more efficient by enabling direct intraoperative examination for cancer nests and cancer-tonormal tissue margins on the patient; this will reduce the number of excisions and avoid frozen histology. Both the patient and surgeon will save several hours per procedure in the operating room. Although proposed for Mohs surgery of BCCs, this real-time intra-
Studies 29
operative imaging modality may, in fact, prove useful in a variety of other microsurgical settings. The research will be a collaboration between Northeastern University (Boston) and Memorial Sloan-Kettering Cancer Center (New York). This project will be implemented in two phases: (1) an ex vivo study using freshly excised skin specimens from Mohs surgeries, to (a) design a confocal microscope that mimics the Mohs surgeon's examination of frozen histology: rapid low-resolution examination of BCC nests in wide fields-of-view followed by high-resolution inspection of nuclear morphology in small fields-of-view, and develop (b) optimum contrast enhancement methods using topical acetic acid (induces condensation of chromatin that increases light backscatter from nuclei) and optical crossed polarization (suppresses light backscatter from the surrounding normal dermis), (c) optimum hemostasis methods using either topical aluminum chloride or electrocautery, (d) image understanding by detailed correlation of images to histology; and (2) an intraoperative study, involving (a) design of a specialized confocal articulated telescope, to enable (b) imaging of BCCs on patients during surgery, to evaluate the optimum contrast enhancement and hemostasis methods, correlate confocal images to histology and quantitatively determine diagnostic/screening accuracy. The overall goal is to develop an optical (confocal) intraoperative imaging instrument for Mohs and other modes of microsurgery. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: LOW BACK PAIN--A MULTICENTER RANDOMIZED TRIAL Principal Investigator & Institution: Weinstein, James N.; Professor; Community and Family Medicine; Dartmouth College 11 Rope Ferry Rd. #6210 Hanover, NH 03755 Timing: Fiscal Year 2001; Project Start 04-JUL-1999; Project End 31-MAY-2004 Summary: Low back pain is considered one of the most widely experienced health problems in the U.S. and the world. This condition is second only to the common cold as the condition for which patients most frequently see a physician or suffer days lost from work. Estimated costs to those who are severely disabled from low back pain range from 30-70 billion dollars annually. Rates of spinal surgery in the U.S. have increased sharply over time, and 15-fold geographic variation in rates of these surgeries has been documented. In many cases the rates of surgery appear to be determined by where one lives and who one sees. Despite these trends, there is little evidence proving the effectiveness/efficacy of these therapies over non-operative management. This study will use the unique resource of the National Spine Network to conduct multicentered, randomized, controlled trials for the three most common diagnostic groups for which spine surgery is performed: lumbar intervertebral disc herniation (IDH), spinal stenosis (SpS) and spinal stenosis secondary to degenerative spondylolithesis (DS). The trials will compare the most commonly used standard surgical treatments to the most commonly used standard non-operative treatments. The study will be conducted at 16 sites throughout the United States. The primary endpoints of the study will be changes in general health-related quality of life as measured by the SF-36 health status questionnaire and spine-related disability as measured by the Oswestry Low Back Pain questionnaire. Secondary endpoints will include patient satisfaction with treatment, resource utilization for estimation of cost, and utility for current health for estimation of quality-adjusted life years (QALYs). The latter two endpoints will be used to complete a formal cost-effectiveness evaluation. Patients will be followed a minimum of 24 months with visits scheduled at 3, 6, 12, and 24 months. Data on all endpoints will be collected at each study visit. If possible, extended follow-up visits will be scheduled at 36 and 48 months. We anticipate that a total of 1450 subjects will be enrolled and randomly allocated. An additional observational cohort will be tracked to assess health and

resource outcomes. Data from the RCT and observational cohorts will be integrated to formally estimate the cost-effectiveness of operative versus non-operative interventions for IDH, SpS, and DS. Based on this trial we will, for the first time, have scientific evidence as to the relative effectiveness/efficacy of surgical versus non-surgical treatment for these three common lumbar spine conditions.

Project Title: MEASURING THE EFFICACY OF ENDOVASCULAR TREATMENT OF AAA Principal Investigator & Institution: Faries, Peter L.; Surgery; Weill Medical College of Cornell Univ New York, NY 10021 Timing: Fiscal Year 2003; Project Start 08-APR-2003; Project End 31-MAR-2008 Summary: (provided by applicant): This proposal describes a five year training program for the development of an academic career in Vascular Surgery for the Principal Investigator, who has completed a structured residency in Vascular Surgery at the Beth Israel Deaconess Medical Center / Harvard Medical School and is currently an Assistant Professor of Surgery in the tenure track at the Mount Sinai School of Medicine. The Mentored Scientist Clinical Development Award will support the development of the Principal Investigator, a vascular surgeon who is trained in experimental methods, into an independent investigator. The program will allow him to expand his expertise in vascular surgery research to develop, coordinate and translate laboratory findings into practical clinical applications for the endovascular treatment of patients with abdominal aortic aneurysms. The program will be performed under the mentorship of Valentin Fuster, M.D., Ph.D. He is the past-president of the American Heart Association, Chairman of the Fellowship Training Directors Program of the American College of Cardiology and Director of the Cardiovascular Institute at the Mount Sinai Medical Center and a Professor of Medicine at the Mount Sinai School of Medicine. He has trained 38 research fellows, many of whom now direct independent laboratories. Juan Badimon, Ph.D., Professor of Medicine, will provide further supervision and training in the areas of thrombus formation and organization. Michael Marin, M.D., Professor of Surgery, a leading pioneer of endovascular stent graft treatment of abdominal aortic aneurysms will enhance the clinical applicability of the hypotheses to be tested. The focus of the research will be measuring the efficacy of endovascular stent graft treatments of abdominal aortic aneurysms. Abdominal aortic aneurysms are a leading cause of death due to aneurysm rupture. Although surgery is the only effective treatment, endovascular surgical techniques utilizing stent grafts have reduced the morbidity of repairing abdominal aortic aneurysms considerably. Endovascular treatments are designed to eliminate arterial perfusion of the aneurysm and thereby eliminate the risk of aneurysm rupture. Although significant advances have been made, the effectiveness of endovascular treatments in eliminating pressure within the aneurysm has not been definitively demonstrated. In addition, no non-invasive means of confirming successful and ongoing elimination of pressure from the aneurysm has been developed. The study will use an experimental model of abdominal aortic aneurysm with an implanted pressure transducer, developed in the principal investigator's laboratory. The effect of retrograde perfusion of the aneurysm sac on intra-aneurysmal pressure after treatment with an endovascular stent graft will be evaluated. The impact of stent graft porosity on the transmission of pressure to the aneurysm will also be studied. Pressure within the aneurysm sac will be correlated with the change in the cross-sectional area and volume of the aneurysm during systole and diastole using cine magnetic resonance imaging. This information may provide a non-

invasive means of confirming the success of endovascular stent graft treatment in eliminating pressure from the aneurysm. The rich academic environment provided by the Mount Sinai School of Medicine and the Departments of Surgery and Medicine / Cardiology with the diverse resources and enthusiasm for promoting scientific research will maximize the potential for the principal investigator to establish an academic career as a clinician scientist.

Project Title: MECHANISMS DEFENDING FAT MASS IN HUMAN AFTER LIPECTOMY Principal Investigator & Institution: Eckel, Robert H.; Professor of Medicine,; Medicine; University of Colorado Hlth Sciences Ctr P.O. Box 6508, Grants and Contracts Aurora, CO 800450508 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-MAY-2008 Summary: (provided by applicant): Suction lipectomy (liposuction) is the most frequently performed esthetic procedure in the western world today; yet, there are no data to demonstrate that the regional removal of adipose tissue mass persists or that adipose tissue hypertrophy and/or hyperplasia does not occur after liposuction to defend body fat. We have published that by one yr., reduction at the lipectomized site occurs with variable increases in the circumference of non-lipectomized subcutaneous sites. Moreover, our unpublished data show that insulin sensitivity was inversely related to increases in circumference of both the lipectomized and non-lipectomized sites. Therefore, the goals of this study are to: 1) determine if suction lipectomy fails to modify regional and/or total body fat over 3 yr, 2) determine if the expression of genes of adipocyte differentiation and/or inflammation or fibrosis predict adipose tissue regional expression in the control and/or lipectomized site, and 3) assess novel adipose tissue genes that predict the response of regional adipose tissue to suction lipectomy. Men and women (n=54) will be randomly assigned to either a control or a surgery group. Lipectomized sites will include the abdomen for men and the hips and thighs for women. All eligible volunteers will complete body measurement visits at the beginning of the study and then at 6 wk and 6, 12, 24, and 36 mos. This visit will include ht, wt, and resting metabolic rate, and regional circumference (arms, thighs, waist, and hips), body fat composition (DEXA), and MRI (xiphoid to knees and upper arms) to determine fat distribution. All volunteers will also undergo a euglycemic clamp to assess insulin action at baseline, 6 wk, and 6 mo, as well as adipose tissue biopsies which will be analyzed for fat cell volume, genes related to regional inflammation and fibrosis and adipose tissue differentiation, and novel gene expression using DNA gene array technology. For those in the surgery group, suction lipectomy will be scheduled within 2 wk of the baseline measurements. Control subjects will be offered suction lipectomy at the end of the 3- yr study under the same protocol guidelines and benefits as those volunteers randomized to the surgery group. These studies will not only evaluate the efficacy of suction lipectomy and the genetic defense of body fat in humans, but may additionally provide insights into the regulation of regional adipose tissue distribution in humans.

Project Title: MEDICAL AND SURGICAL TREATMENT OF ESOPHAGEAL REFLUX Principal Investigator & Institution: Finlayson, Samuel R.; Surgery; Dartmouth College 11 Rope Ferry Rd. #6210 Hanover, NH 03755
32 Surgery
Timing: Fiscal Year 2002; Project Start 01-JUN-2002; Project End 31-MAY-2004 Summary: Gastroesophageal reflux disease (GERD) is one of the most common disorders of the gastrointestinal tract. Approximately 75 million Americans suffer from "heartburn", the most typical symptom of GERD. Heartburn can severely impact quality of life and leads to an estimated 15 million physician consultations per year. Both medical and surgical treatments have been shown to be effective in controlling symptoms of GERD, but surgical intervention has traditionally been reserved for selected patients with intractable symptoms. However, for both medical and surgical treatment of GERD, the landscape has changed significantly in the last decade. Proton pump inhibitor therapy has proven vastly superior to older anti- acid medications. Concurrently, the advent of minimally invasive laparoscopic surgery as substantially lowered the threshold for surgical treatment of GERD and led to substantial increases in rates of anti-reflux surgery. Both of these advances have sharpened the debate surrounding optimal treatment of GERD, but at present there is insufficient evidence on which to base comparispon of medical and surgical treatment. A careful, prospective, multi-enter, randomized clinical trial would be the ideal mechanism for comparing proton pump inhibitor therapy and laparoscopic anti-reflux surgery for GERD. The purpose of this application is to seek funds to design and plan such a trial. As members of an experienced clinical trial consortium, we recognize that conducing this trial will require successfully overcoming several important challenges, including issues of patient recruitment and retention, generalizability, and measurement of quality-of-life outcomes. The R03 grant would provide the required financial resources to carefully address these challenges. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: MIDDLE-EAR MECHANICS IN NORMAL AND PATHOLOGICAL EARS Principal Investigator & Institution: Merchant, Saumil N.; Associate Professor of Otology & Laryngo; Massachusetts Eye and Ear Infirmary 243 Charles St Boston, MA 02114 Timing: Fiscal Year 2001; Project Start 01-APR-2001; Project End 31-MAR-2006 Summary: The goal of this work is to understand sound transmission through normal, diseased and reconstructed middle ears so that better diagnostic tests and surgical procedures can be offered to patients with middle-ear disease. Middle-ear diseases such as chronic otitis media and otosclerosis, which affect over 10 million people in the US, are common causes of significant conductive hearing loss. The current battery of diagnostic tests (otoscopy, audiometry, tympanometry) cannot reliably differentiate ossicular pathology, especially when the tympanic membrane is intact or if there has been prior middle-ear surgery. Additionally, it is commonly acknowledged that postoperative hearing results after tympanoplasty procedures for chronic otitis media are often unsatisfactory. Factors contributing to the modest nature of surgical results include lack of clear understanding of the critical structure-function relationships in the reconstructed ear, and failure of current diagnostic tests to determine such relationships. Laser Doppler vibrometry has been demonstrated to be more sensitive than audiometry and tympanometry in assessing middle- ear function, because the laser spot (only 100 micrometers diameter) can be focused at various points on the tympanic membrane and malleus, and because vibrometry is unaffected by the ear canal (unlike tympanometry). We propose to use vibrometry, other acoustical measurements (admittance and reflectance), audiometry and tympanometry to investigate structure-function relationships in (a) normal ears, (b) diseased ears with ossicular pathologies, and (c)
Studies 33
reconstructed ears that have undergone surgery for chronic otitis media or otosclerosis. Similar vibrometry and acoustical measurements will also be made in a surgicallymodified human temporal bone preparation that mimics diseased and reconstructed ears. Our approach should lead to a better understanding of the structure-function relationships in normal and pathological middle ears, improved differential diagnosis of middle-ear lesions, better pre-operative patient counseling and surgical planning, optimization of surgical techniques and hearing results, and reduction in the number of failed surgeries.

Project Title: MOLECULAR BASIS OF POSTOPERATIVE DELIRIUM IN THE ELDERLY Principal Investigator & Institution: Kwatra, Madan M.; Associate Professor; Anesthesiology; Duke University Durham, NC 27706 Timing: Fiscal Year 2003; Project Start 15-JAN-2003; Project End 31-DEC-2007 Summary: (provided by applicant): Postoperative delirium is a frequent complication in the elderly, with an incidence rate ranging from 10% to 70%. It is associated with several adverse outcomes, including prolonged hospitalizations, poor functional recovery, and in some cases increased mortality. Because the proportion of elderly surgical patients is increasing, it is critical to understand the pathophysiology of postoperative delirium. Several neurotransmitter systems appear to be involved in delirium, and the proposed studies will test the hypothesis that postoperative delirium is associated with changes in the expression of specific genes and proteins Identification of these genes and proteins will lead to novel strategies for diagnosing, treating, and possibly preventing postoperative delirium. The first aim will be to examine changes in gene expression in peripheral blood mononuclear cells (PBMCs) using DNA microarrays. This aim is based on our preliminary data indicating that surgery causes a twofold or greater change in the expression of 466 genes in PBMCs, with 329 getting up-regulated and 137 getting down-regulated. The magnitude of this surgery-inducing change in gene expression is unprecedented and raises the probability that some of these genes are the markers of and/or the cause of postoperative delirium. We will enroll 250 elderly patients (>65 years old) undergoing hip or knee replacement-a procedure that causes about 20% incidence of postoperative delirium-and assess postoperative delirium using a battery of instruments. Gene expression in pro- and post-surgery PBMCs from 50 delirious and 50 non-deledous patients will be determined using a DNA microarray chip containing 12,000 human genes. Statistical analysis of the gene expression data will identify the cluster of genes associated with postoperative delirium. The second specific aim will be to identify serum proteins that change with delirium by examining global protein expression using 2D-gel electrophoresis/mass spectrometry. The PI and the co-PI have assembled an interdisciplinary team with expertise in anesthesiology, bioinformatics, geriatrics, molecular pharmacology, nursing, psychiatry, psychology, orthopedic surgery, and statistics. In addition, consultants are available with expertise in delirium, DNA microarrays, and mass spectrometry. Our team is therefore in a unique position to successfully complete the proposed studies.

Project Title: MUSCLE FUNCTION AFTER TENDON TRANSFER SURGERY Principal Investigator & Institution: Delp, Scott L.; Chair; Mechanical Engineering; Stanford University Stanford, CA 94305
34 Surgery
Timing: Fiscal Year 2001; Project Start 01-SEP-1999; Project End 31-MAY-2003 Summary: The goal of this work is to provide a scientific basis for treating stiff-knee gait, a common movement abnormality among children with cerebral palsy. The rectus femoris transfer surgery is frequently performed to treat stiff-knee gait. In this surgery, the distal tendon of the rectus femoris is detached from the patella and reattached to one of several sites posterior to the knee. This surgery is thought to convert the muscle from knee extensor to a knee flexor thereby allowing the muscle to assist knee flexion during walking. However, the surgical outcomes are inconsistent, and the in vivo function of the transferred rectus femoris is unknown. We hypothesize that remodeling of the rectus femoris after surgery results in adhesions to surrounding tissues in some patients, which dramatically alters the postoperative function of the muscle and degrades the outcome of the surgery. This study will use biomechanical models, magnetic resonance imaging techniques, and experimental measurements on human subjects to evaluate the function of the rectus femoris following tendon transfer. Aim 1 will assess the potential of the rectus femoris to flex the knee after transfer. Biomechanical models, constructed from MR images, will provide quantitative descriptions of musculoskeletal geometry for 8-12 patients undergoing rectus femoris transfers to different surgical sites. This work will determine the differences in the knee flexion moment arm of the rectus femoris after transfer to different sites. Aim 2 will determine if forces at the proximal and distal tendons of the rectus femoris are equal after transfer, or if force at the distal tendon is disrupted after the surgery. Hip and knee moments, generated by selective stimulation of the rectus femoris, will be measured in subjects with stiff-knee gait. Tendon forces will be estimated by dividing the measured moments by the corresponding moment arms obtained from the MRI-based models. Aim 3 will use cine phase-contrast MR imaging to analyze and visualize the relative motions of the rectus femoris and the surrounding muscles in vivo. The extent of scar formation following rectus femoris transfer will be investigated, and the effects of adhesions on the mechanics of the muscle will be assessed. Aim 4 will examine how postoperative function of the rectus femoris influences knee motion during gait. The success of this work will result in better, more predictable treatment outcomes.

Project Title: MYELOMENINGOCELE REPAIR RANDOMIZED TRIAL-DSCC Principal Investigator & Institution: Thom, Elizabeth A.; Associate Research Professor of Statisti; Statistics; George Washington University 2121 I St Nw Washington, DC 20052 Timing: Fiscal Year 2002; Project Start 11-APR-2002; Project End 31-MAR-2007 Summary: Since 1997, 180 fetuses have had in utero closure of myelomeningocele (MMC) by open fetal surgery. Preliminary clinical evidence suggests that this procedure reduces the incidence of shunt-dependent hydrocephalus and restores the cerebellum and brainstem to more normal configuration. However, clinical results of fetal surgery for MMC are based on comparisons with historical controls and examine only efficacy and not safety. The Myelomeningocele Repair Randomized Trial is a multi-center unblinded randomized clinical trial of 200 patients that will be conducted at three Fetal Surgery Units (FSU), the University of California-San Francisco, Children's Hospital of Philadelphia, and Vanderbilt University Medical Center. The primary objective of the trial is to determine if intrauterine repair of fetal myelomeningocele at 18(0) to 25(6) weeks gestation improves outcome, as measured by 1) death or the need for ventricular decompressive shunting by one year of life and 2) death or Bayley Mental Development Index, as compared to standard postnatal repair This proposal is for the George Washington University Biostatistics Center to serve as the Data and Study Coordinating
Studies 35
Center (DSCC) for the MMC Repair Trial. The purpose of the DSCC, an important but independent member of the multi-center collaborative study group, is to provide expertise and support in study design, study conduct and statistical analysis. We will provide scientific leadership in the design of the study and prepare the final study documents including the protocol, manual of operations and case report forms. The DSCC will be responsible for all publicity for the MMC Repair Trial such as establishing a central web site, mailing of physician brochures, presenting trial information at appropriate professional meetings and placing print advertisements in medical journals and patient oriented publications. We will also serve as the central referral site for patients to learn more about the trial, conduct preliminary review of patient eligibility and assign the patient to a Fetal Surgery Unit for final evaluation. The DSCC will maintain an Internet randomization system and web-based data entry system for the patient eligibility data. We will provide a comprehensive data processing system including central data entry, data base management and data quality control. The DSCC will use appropriate statistical techniques to conduct interim and final analyses. We will assist the investigators in preparation of manuscripts and abstracts from study results. In summary, we will participate in cooperation with the FSUs on the proposed trial with the goal of demonstrating whether fetal intervention offers improved outcome with a reasonable quality of life for spina bifida children.

Project Title: MYOCARDIAL GENE TRANSFER DURING CARDIAC SURGERY IN SWINE Principal Investigator & Institution: Milano, Carmelo A.; Surgery; Duke University Durham, NC 27706 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2007 Summary: (provided by applicant): A variety of experimental myocardial molecular alterations have suggested that genetic therapies may impact on cardiac disease (24,34,35). Vascular growth factor genes may serve in the treatment of coronary artery disease or ischemic cardiomyopathy (29,45,46). States of left ventricular dysfunction or heart failure (HF) can be ameliorated with exogenous genes which alter the native #adrenergic receptor (AR) system or which improve myocardial calcium handling(24,34,37). However, in order to utilize such genetic strategies to treat cardiac disease, safe and efficient methods for cardiac gene delivery must be developed. Importantly, to achieve alterations of heart function or structure, efficient gene delivery methods must be developed to transfect a majority of themyocardium. In this proposal, we investigate myocardial gene transfer in adult swine models employing cardiac surgery. The primary components of modem cardiac surgery include cardiopulmonary bypass (CPB), cardioplegic arrest and crossclamping of the ascending aorta. These steps may facilitate safer gene delivery since they result in an interruption of the coronary Circulation and an isolation of the coronary circulation from the systemic circulation, making "cardioselective" gene transfer possible.The central hypothesis is that global myocardial transgene expression and secondary functional changes can be achieve in adult swine utilizing adenoviral delivery during simulated cardiac surgery. The specific aims are: 1. Achieve safe and efficient myocardial gene transfer in adult pigs utilizing adenoviral and advanced generation vectors, delivered during simulated cardiac surgery. 2. Characterize post-cardiac surgery left ventricular dysfunction in adult pigs :and :reverse the dysfunction with betaAR based gene therapy delivered during the surgery. 3. Employ functional transgenes to achieve positive inotropic effects in a swine pacing heart failure model. i. Study inotropic effects of transgenes in cultured LV

myocytes from failing pig hearts. ii. Deliver functional transgenes to failing pig hearts during simulated cardiac surgery and evaluate effect on LV performance. These studies will help to develop safer and more efficient methods for gene delivery which can be coupled to cardiac surgery. As our knowledge advances, gene therapy may supplement established surgical treatments. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

Project Title: NATURAL HISTORY AND TREATMENT RESPONSE OF AVMS Principal Investigator & Institution: Halim, Alexander; Anesthesia and Perioperative Care; University of California San Francisco 500 Parnassus Ave San Francisco, CA 94122 Timing: Fiscal Year 2002; Project Start 01-JUN-2002; Project End 31-MAY-2003 Summary: (provided by applicant): Brain arteriovenous malformations (BAVM) are usually detected only when the patient presents with intracranial hemorrhages, seizures, headaches, focal neurological deficits, or other disorders. A smaller number are detected incidentally. Although BAVM themselves are rare, the severity of the clinical presentations underscores the need for a better understanding of etiology, natural history, and prognosis of the disorder. The primary reason for treating BAVM is the prevention of intracranial hemorrhage. However, the risk associated with treatment must be weighed against that of natural history of BAVM, on which there is little data. In addition, there is controversy involving the relative efficacies of the 2 most practiced treatment modalities: open surgery and stereotactic radiosurgery. Most of what is known about BAVM comes from referral series. There is a paucity of data from population-based studies. In this project, we will examine patient and BAVM characteristics in relation to BAVM presentation and subsequent hemorrhage using both referral-based and population-based data. We will especially focus on the
Studies 37
epidemiological issues involved in BAVM research methodologies. Our project will also investigate the settings for clinical equipoise in BAVM treatment using an improved observational study design. Results of this latter analysis will significantly contribute to the planning of a future randomized clinical trial for BAVM treatment, comparing open surgery with radiosurgery. This proposed project will serve as a critical training experience for the Principal Investigator, by affording him the opportunity to apply his epidemiological background and augment his research skills in preparation for independent scientific research. The results of this project may additionally further our understanding of the natural history and risk factors for intracranial hemorrhages in patients with BAVM, as well as evaluate the safety and efficacy of the different treatment modalities.

BIOMATERIALS
FOR
SUTURELESS
OPHTHALMIC
Principal Investigator & Institution: Grinstaff, Mark W.; Associate Professor; Chemistry; Duke University Durham, NC 27706 Timing: Fiscal Year 2002; Project Start 01-FEB-2002; Project End 31-JAN-2006 Summary: We propose a systematic study to test the hypothesis that light-activated polymers can replace or supplement conventional sutures in ophthalmic surgeries. Specifically we have synthesized novel dendrimers, termed biodendrimers, composed of biocompatible monomers such as glycerol and lactic acid. We will take advantage of the favorable chemical and physical properties of these photocrosslinkable biodendrimers to seal corneal perforations and to secure corneal autografts in human enucleated eyes and chicken eyes in vivo. Accordingly, answers will be sought to the following questions: 1. Can the chemical structure of a biodendrimer be optimized to afford specific properties required for sutureless ophthalmic surgeries? 2. Will a biodendrimer seal a 3 mm full thickness linear or stellate corneal perforation? 3. Will a biodendrimer secure a corneal autograft? Corneal perforation and corneal transplantation are two models of corneal tissue injury that are ideal for testing new tissue sealants. The traditional approach to repair both these injuries involves sutures, yet the use of sutures affords a number of limitations and complications. Tissue adhesives such as cyanoacrylate are becoming more widely accepted in various corneal procedures, however these materials have only met with marginal success. Improvements made to the composition and/or to the method of application can potentially enhance the effectiveness of tissue sealants for treating wounds and even broaden the scope of clinical use. Potential indications in other ophthalmic areas include ruptured globe repair, wound closure in cataract surgery, and wound modulation in glaucoma filtering surgery. The novel photocrosslinkable biodendrimers described in this proposal represent a new class of ophthalmic tissue adhesives that may accomplish the objectives cited above sealing corneal perforations, and securing corneal autografts. Successful completion of these studies may lead to new ophthalmic surgical techniques, procedures, and treatments using unique, custom-designed biomaterials.

38 Surgery
Timing: Fiscal Year 2001; Project Start 08-FEB-1999; Project End 31-JAN-2003 Summary: (Adapted from investigator's abstract) Many patients have advanced cardiac disease, necessitating complicated cardiac surgery or transplantation. During cardiac surgery, including transplantation, the heart is rendered ischemic; and blood flow to the heart is stopped either to undertake the surgery or to transport the organ, which is currently limited to 4-6 hours. In order for the patient to be removed from cardiopulmonary bypass and return to activity, the heart has to function well following cardiac surgery. Any enhancement in myocardial energy preservation will increase the number of positive outcomes for patients and improve the quality of patient care. Interestingly, hibernating animals can preserve up to 90% of the energy required during normal euthermic metabolism. The mechanism of this energy preservation during hibernation is currently unknown; however, many studies point to an opioid "trigger" molecule, which has been termed the hibernation induction trigger or HIT. The opiate nature of HIT is well established, as HIT can be reversed or retarded by opiate antagonists. Evidence indicates that HIT initiates its potential metabolic inhibitory effects through specific membrane opioid receptors, particularly delta receptors. Delta opioids have been shown in many models and the investigators' preliminary results to produce profound behavioral, physiological and metabolic inhibitory effects favoring survival at the whole animal, the organ and the cellular level. The proposed study will investigate the mechanisms of action of delta opioids at both the organ and subcellular levels. These studies could result in extended safe cardiac ischemic time with potential application to cardiac surgery and cardiac transplantation. In these proposed isolated heart studies, the investigators will determine if delta opioids provide enhanced myocardial protection during ischemia. The investigators will also seek to elucidate the intracellular mechanism by which the delta opioids protect the ischemic myocardium. The ability of the delta opioids to effect myocardial protection suggests that the use of these molecules may be valuable in many clinical scenarios resulting in ischemia.

Project Title: OPTIMIZING LIFESTYLE ADJUSTMENT IN WEIGHT LOSS SURGERY Principal Investigator & Institution: Kalarchian, Melissa A.; Assistant Professor; Psychiatry; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, PA 15260 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2007 Summary: (provided by applicant): Although surgery is the treatment of choice for severe obesity, very little is known about the relationship of lifestyle factors to patient outcomes after operation. This Mentored Patient-Oriented Research Career Development Award (K23) describes integrated training and research plans designed to prepare the candidate to pursue research on helping patients achieve optimal weight loss and lifestyle adjustment after bariatric surgery. A model of treatment is presented in which an intervention targeting behavioral (eating, activity, and compliance) and psychosocial factors (e.g., symptoms of binge eating and personality style) is expected to impact weight loss, health-related quality of life, and overall well-being. Advanced training in genetic and environmental influences on severe obesity, an expanded working knowledge of how surgeons treat severely obese patients, and consolidation of skills in longitudinal research methodology will assist in refining and developing this model. The research plan involves prospectively tracking weight-related variables, eating and activity, compliance and satisfaction, and psychosocial factors over time among a group severely obese patients undergoing surgery for weight loss (Study 1),

and using the data to inform the development and evaluation of a lifestyle intervention geared to optimizing outcomes after operation (Study 2). The comprehensive lifestyle intervention will encompass 1) encouraging healthy eating habits, 2) increasing physical activity, 3) enhancing psychosocial adjustment. Adaptations to treatment will accommodate the unique needs of bariatric surgery patients. Specifically, a modular treatment format will address patients' changing needs in the preoperative, postoperative, and longer-term adjustment phases. Additionally, the intervention will be developed for delivery one-on-one at routine clinic visits with supplemental contact via the Internet. The data collected will contribute to the preparation of an R01 application that will involve conducting a full-scale randomized clinical trial to evaluate the modular, computer-aided lifestyle intervention. Future work may focus on adding adjunctive treatment components such as weight loss medication, the effects of which have not been adequately studied in bariatric surgery patients.

Project Title: ORAL INFLAMMATION
SURGERY
AND
INITIATION
OF
NEUROGENIC
Principal Investigator & Institution: Swift, James; Diagnostic/Surgical Scis; University of Minnesota Twin Cities 200 Oak Street Se Minneapolis, MN 554552070 Timing: Fiscal Year 2001; Project Start 01-FEB-1995; Project End 31-MAY-2004 Summary: (Adapted from investigator's Abstract): Although neuropeptides are well known to exert a wide range of pro-inflammatory effects after administration of pharmacological dosages into normal tissue, relatively little is known about their physiologic functions in regulating inflammation and healing. The applicants have developed a technique for collecting inflammatory mediators, including neuropeptides, by implanting microdialysis probes into surgical wounds of awake, post-oral surgery patients or in anesthetized rats following tissue injury. Ongoing studies performed by the applicants show that physiologic levels of immunoreactive substance P (iSP) are released into the surgical wounds of dental patients, and that bradykinin, prostaglandin E2 (PGE2) and leukotriene B4 (LTB4) all mediate, via receptor-dependent mechanisms, increases in surgical wounds of iSP levels. In this competing renewal application, the proposed multidisciplinary studies are designed to identify physiologic systems regulating wound levels of iSP in humans, determine whether efferent dorsal root reflexes contribute to the initiation of neurogenic inflammation in human and rat surgical wounds, and to evaluate whether elevated iSP concentrations, detected in surgical wounds, mediate the development of surgery-induced neurogenic inflammation and wound healing. The applicants propose both clinical and animal studies. Clinical Studies: 1. To determine the peripheral effects of drugs that modulate neurogenic inflammation (capsaicin) on altering tissue levels of i-SP and an index of neurogenic inflammation (local hyperthermia) in the surgical wounds of awake patients following extraction of impacted mandibular third molars. 2. To determine the contribution of efferent neuronal outflow (e.g., dorsal root reflexes) on the initiation of neurogenic inflammation in the surgical wounds of awake patients following extraction of impacted mandibular third molars. Animal Studies: 1. To determine the magnitude of the neurogenic component of inflammation observed following surgical extraction of teeth in anesthetized rats. 2. To determine whether endogenous substance P (SP) contributes to the neurogenic component of inflammation observed following surgical extraction of teeth in anesthetized rats. 3. To determine the magnitude of the neurogenic component of wound healing observed following surgical extraction of teeth in anesthetized rats. 4. To determine whether endogenous SP contributes to wound healing

observed following surgical extraction of teeth in anesthetized rats. Collectively, the proposed studies will determine the efferent regulation of iSP levels in surgical wounds of humans, and, in a parallel rat model, determine the role of SP in post-surgical inflammation and wound healing. This knowledge may well provide a physiological basis for improved surgical outcomes. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ORTHOPEDIC ANALYSIS--DECISION AIDS FOR ELECTIVE SURRGERY Principal Investigator & Institution: Llewellyn-Thomas, Hilary; Professor; Dartmouth College 11 Rope Ferry Rd. #6210 Hanover, NH 03755 Timing: Fiscal Year 2003; Project Start 01-JAN-2003; Project End 31-DEC-2007 Summary: This study explores the opinions of members of the American Academy of Orthopedic Surgeons (AAOS) about using patients' decision aids (DAs) for elective surgery for herniated disc / spinal stenosis. These newly developed, high-quality DAs have been carefully assessed in randomised controlled study designs. The evidence indicates that they effectively help with shared decision-making (SDM). However, before introducing these DAs into regular use in clinical practice, we need to know surgeons' opinions about their "real world" usefulness. This project assesses surgeons' opinions about whether these DAs could complement their usual approaches to providing patients with treatment information, the relative importance of various cognitive, affective, and behavioural outcomes in evaluating their effectiveness, the most suitable media for DAs, and the perceived factors hindering / promoting the adoption of well-developed and carefully evaluated decision aids in their own clinical settings. It is also important to determine if these opinions about DAs are related to whether a surgeon's practice is located in a geographic region with a relatively higher / lower elective surgical rate. These data will be collected in a mailed survey. The recruitment target is 520 members of the AAOS (440 in a general sample and 40 in each of 2 geographic sub-samples). The study design involves a series of mailouts, an engaging questionnaire, and an explicit follow-up strategy. The responses from the 440 in the general sample will be analysed descriptively; the results for the two (i.e. higher / lower) geographic regions will be tested for differences. The ultimate objective is to provide empirical data that can guide: a) the valid design of future evaluative studies of these newly-developed patients' decision aids regarding elective orthopaedic surgery; and b) the clear identification of implementation / dissemination strategies most likely to support the incorporation of effective decision aids into regular orthopaedic surgical practice. Future work will involve the development of Web-based capabilities to collect comparable data from the patients' perspective. This will allow assessment of the extent to which surgeons' and patients' opinions about SDM are/are not congruent, across areas of regional disparity in surgical rates. Ultimately, these efforts could, in turn, help to foster greater degrees of physician-patient satisfaction with the communication processes that occur in orthopaedic surgery.

Summary: Anterior cruciate ligament (ACL) injury is prevalent and often leads to instability, quadriceps muscle weakness and osteoarthritis. (OA) Many of those with chronic ACL deficiency have evidence of knee OA years after ACL rupture. Weakness and instability experienced by those who do not compensate well for ACL deficiency (non-copers) independently lead to compensation strategies that could precipitate or worsen knee OA. These poor compensation strategies do not uniformly resolve after surgical reconstruction and those who undergo reconstruction also have an increased risk of developing knee OA. The overall goal of this work is to determine whether effective rehabilitation programs to dynamically stabilize the knee reduce the adaptations that lead to osteoarthritis in a population at great risk for the development of knee OA. Eighty individuals with ACL rupture who are scheduled for surgery will be randomly assigned to a group that includes a form of neuromuscular training called perturbation training, or a standard group. They will be evaluated before and after surgery using motion analysis and radiography. In vivo measures of kinematics, kinetics, tibial translation and EMG based models of joint compression will be used for comparison. This randomized trial is designed to demonstrate that, after preoperative rehabilitation that includes perturbation training, movement patterns adopted by noncopers: 1) demonstrate improve joint stability and reduced muscle cocontraction, 2) persist after reconstruction and 3) result in better functional outcomes after reconstruction and 4) lead to the development of less knee pain and OA over time than standard preoperative treatment strategies. The information derived from this project will provide valuable insight into the management of the approximately 100,000 Americans who rupture their ACLs each year and undergo reconstructive surgery. More importantly, if the perturbation training program's ability to induce dynamic knee stability actually results in joint protection, its application to others at risk for the development knee OA may help reduce the incidence of this disabling clinical condition.

Project Title: PATHOPHYSIOLOGIC RESPOSE TO FETAL CARDIAC SURGERY Principal Investigator & Institution: Hanley, Frank L.; Surgery; University of California San Francisco 500 Parnassus Ave San Francisco, CA 94122 Timing: Fiscal Year 2001; Project Start 01-FEB-1992; Project End 31-MAR-2002 Summary: The goal of this ongoing project is to continue the development of fetal cardiac surgery. Certain congenital defects are uncorrectable after birth and there is a clear advantage for intrauterine corrective surgery. This approach requires an understanding of the physiological effects of surgical intervention and extracorporeal circulation on the fetus. Our work in this area to date has allowed us to gain a substantial but incomplete understanding of these issues. The three major pathophysiological responses which limit fetal survival following intervention and extracorporeal circulation (which we identified in the original grant proposal) include: 1. The loss of fetal cardiovascular homeostasis in the pre-bypass phase of fetal intervention. 2. The "step function" rise in fetal vascular resistance at the institution of fetal bypass which is associated with acute decompensation. 3. The gradual rise in placental vascular resistance during and after fetal bypass which results in depressed placental blood flow. The specific focus of this project remains as stated in the original proposal, to identify the mediators and detailed pathophysiologic mechanisms of these three responses with an eye towards clinical application of this information to advance the development of human fetal cardiac surgery. Each of the three responses will be systematically evaluated. Experiments examining the pre-bypass problem will focus on the role of the fetal stress response. Further understanding of this response is presently
42 Surgery
limited by our fetal animal model (sheep). We propose to study the efficacy of narcotic anesthesia in blunting the stress response in an instrumented primate model. Experiments addressing the 'step function' rise in fetal vascular resistances will examine the inhibition of this response using specifically designed bypass circuitry. Our methodology will include ultrasonic flow transducers to continuously measure instantaneous changes in organ flow in addition to our more specific microsphere techniques, which do not have this capability. In recognition of the multiple factors effecting the placental vasculature, experiments addressing the gradual rise in post bypass placental resistance will examine the role of placental vascular dysfunction in addition to the role of eicosanoids.

Project Title: PATIENT ORIENTED RESEARCH--ORAL AND MAXILLOFACIAL SURGER Principal Investigator & Institution: Dodson, Thomas B.; Associate Professor; Massachusetts General Hospital 55 Fruit St Boston, MA 02114 Timing: Fiscal Year 2001; Project Start 01-FEB-2000; Project End 31-JAN-2005 Summary: Multiple investigators have documented the importance of patient-oriented research in guiding therapy, implementing translational therapies and in evaluating diagnostic or therapeutic outcomes. Due to a shortage of investigators trained to conduct rigorous patient-oriented research in the field of oral and maxillofacial surgery (OMFS), the specialty literature consists largely of case reports and case series. The broad goals of this award are: 1) to develop a longitudinally funded fellowship program dedicated to training oral and maxillofacial surgeons in the principles and practice of clinical investigation; 2) to continue scientifically rigorous clinical research efforts in the area of reconstructive OMFS surgery; and 3) to initiate clinical research in the prevention and treatment of maxillofacial trauma. To accomplish these broad goals, we propose the following Specific Aims which address both the mentoring and patient oriented research aspects of the award: number 1) To establish the first funded fellowship in clinical investigation designed specifically for the training of oral and maxillofacial surgeons in patient-oriented research. Number 2) To measure the efficacy and safety of reconstructing alveolar bone defects with demineralized bone powder (DBP) or guided tissue regeneration (GTR) techniques in a 3rd molar extraction surgical model. Number 3) To determine the sensitivity and specificity of facial injuries as unambiguous diagnostic indicators of domestic violence and number 4) To identify risk factors for poor outcomes following treatment of mandibular condyle fractures. Specific aim 1 uses an extramurally funded two-year grant to support a Fellow studying the principles and practice of clinical investigation. Mentoring surgeons to be skilled clinical investigators addresses the acute shortage of well-trained clinical researchers in the specialty. Specific aim 2 uses an extramural award to conduct a single-blind, randomized clinical trial testing the efficacy of DBP and GTR-therapy for reconstructing alveolar defects following 3rd molar extraction. No current reconstructive techniques are clinically proven to be superior to natural healing of the extraction defect. Specific aim 3 uses a cross-sectional study to determine the diagnostic value of facial injuries as indicators of domestic violence (DV). As DV is characterized by recurrent violent episodes of increasing severity, the early identification of DV victims may prevent future injury. Specific aim 4 uses a retrospective study design to identify patients at risk for poor treatment outcomes after mandibular condyle fractures. Condylar fractures are common and treatment is controversial. Identifying patients at risk for poor outcomes from standard treatment begins to address treatment controversies. This award

Project Title: PERIPHERAL METABOLISM
ARTERIAL
DISEASE
AND
LEG
MUSCLE
Principal Investigator & Institution: Killewich, Lois A.; Surgery; University of Texas Medical Br Galveston 301 University Blvd Galveston, TX 77555 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2006 Summary: (provided by applicant): (provided by applicant): As a vascular surgeon I treat atherosclerosis of leg arteries, known as peripheral arterial occlusive disease (PAOD). PAOD occurs when arteries to the leg become stenosed or occluded, reducing leg blood flow. Subjects experience calf muscle pain with walking, because although the blood supply is adequate to meet the metabolic demands of resting muscle, it is not adequate to meet the increased demands associated with exercise. Leg bypass surgery (femoro-popliteal bypass) increases leg blood flow, but alone does not improve walking abilities and functional status of elderly PAOD subjects. Effective treatment of PAOD will require identification and therapy for other adverse physiological conditions present in elderly PAOD subjects which contribute to their disability. Older subjects also develop sarcopenia, a condition in which muscle mass and function decline with age. At the University of Texas Medical Branch, Dr. Robert Wolfe, a nationally-known authority on leg muscle physiology, is studying sarcopenia in the elderly. He has developed a three-pool model of leg muscle protein metabolism, using infusion of stable isotopes and gas chromatography-mass spectroscopy methodology. He shown that nutritional supplementation (specifically, amino acids) increases leg muscle protein synthesis, and may therefore offer a method for counteracting the effects of sarcopenia. I was recruited to UTMB in 1999, and have formed a collaboration with Dr. Wolfe. In this study, I am proposing to investigate the relationship between PAOD and leg muscle protein synthesis in elderly subjects with PAOD. It is my hypothesis that reduced leg muscle blood flow associated with PAOD will limit the availability of amino acids to leg muscle, and thus further impair protein synthesis. Femoro-popliteal bypass surgery, by increasing blood flow, should increase delivery of amino acids to muscle and hence ameliorate the effects of sarcopenia. It is my ultimate hope that the combined interventions of bypass surgery and nutritional supplementation with amino acids can be used to improve overall functional status of these elderly Americans.

Project Title: PET IN MULTIMODALITY THERAPY FOR ESOPHAGEAL CANCER Principal Investigator & Institution: Levine, Edward A.; Surgery; Wake Forest University Health Sciences Winston-Salem, NC 27157 Timing: Fiscal Year 2001; Project Start 05-FEB-2001; Project End 31-JAN-2003 Summary: Historically, localized cancer of the esophagus was managed by either surgery or radiation therapy alone. Recently, studies have found a substantial improvement in survival when chemotherapy is combined with radiation therapy either alone or as an induction regimen prior to surgery. It has been demonstrated in several clinical trials of chemo- radiation followed by surgery that approximately 30% of patients will have no tumor found in the esophageal resection specimen at the time of resection. Clearly, local control after chemo-radiation is improved with the addition of surgery when residual disease is present. However, there is little data (none of which is
44 Surgery
randomized) demonstrating an outcome advantage with the addition of surgery when patients have achieved a complete pathologic response to preoperative therapy. Further, resection of the esophagus with a pathologic complete response has no clear therapeutic benefit and is associated with considerable morbidity. Consequently, rather than subjecting all patients to a resection, a more logical approach is to further refine current prognostic and diagnostic techniques to allow for a more rational selection of patients at risk of having residual disease after induction chemo-radiation. In a correlative study, we plan to evaluate the utility of [18F]-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) imaging, both before and at the completion of the induction chemo-radiation to assess changes in the tumor uptake FDG. Recent improvements in PET imaging suggest that this tool is sensitive for identifying subclinical disease; either at the time of initial staging or to determine recurrent/persistent disease during and following therapy. Further, although PET holds great promise, it is currently an expensive modality. Consequently, defining the optimal time for its use in a patient's course is clinically important. We plan to correlate the PET findings with endoscopic ultrasound (EUS), and spiral CT imaging to pathologic findings from resected specimens.

Project Title: PHYSIOLOGY CORE Principal Investigator & Institution: Sherwin, Robert S.; Professor of Internal Medicine; Yale University 47 College Street, Suite 203 New Haven, CT 065208047 Timing: Fiscal Year 2003; Project Start 01-JAN-2003; Project End 31-DEC-2007 Summary: The obiective of the Physiology Core is to be a resource for DERC members to facilitate diabetes-related research dealing with biological outcomes in normal and diabetic rodents (rats and mice) as well as in genetically engineered rodents. These activities may require any or all of the following: a) placement of catheters or probes for infusion and sampling (rats and mice), b) isolation of islets (rats and mice), c) help in the performance of glucose clamps or tolerance tests (rats only), and d) measurements of glucoregulatory hormones (rats and mice). The Physiology Core provides the centralized facilities, services and expertise to efficiently accomplish these tasks. It is divided into two Sub-cores, i.e., Animal Surgery and Hormone Assay. The aims of the Animal Surgery Sub-core are two-fold: 1) to provide DERC investigators with laboratory facilities and expertise to conduct diabetes-related, in vivo physiological experiments in awake non-diabetic or diabetic rodents, and 2) to be a resource for DERC members to facilitate islet-related research by providing freshly isolated rodent pancreatic islets, insulinoma lines as well as pancreatic lymph node cells. A centralized facility to conduct surgery for chronic catheter placement to carry out difficult metabolic studies in rodents and to efficiently generate islets is very useful for diabetes research, but is not easily accessible to investigators without previous training or experience. The Sub-Core will provide expertise, services and education, thereby giving DERC members access to the specialized experimental methodologies and the equipment necessary to apply them to diabetes. Moreover, it is anticipated that the Sub-core will provide a vehicle for collaboration between members with basic science research, and members whose focus is clinical physiology and metabolism. The Hormone Assay Sub-core provides DERC members with centralized facilities for measurements of glucoregulatory hormones and neurotransmitters that are derived from animal studies. This component of the Physiology Core takes advantage of the Yale GCRC Core Laboratory that is used for clinical studies. The Subcore benefits from the technical expertise and equipment of an ongoing and productive radioimmunoassay and HPLC

facility, thereby allowing us to maximize quality and minimize the cost of operation. As a result, DERC members have access to a centralized facility that makes available personnel, methodology, instrumentation, and quality control required to efficiently perform hormone assays relevant to diabetes.

Project Title: PILOT--JOINT REPLACEMENT SURGERY: SOCIAL SUPPORT, ETHNICITY AND GENDER Principal Investigator & Institution: Chang, Huan J.; Northwestern University Office of Sponsored Programs Chicago, IL 60611 Timing: Fiscal Year 2002; Project Start 15-FEB-2002; Project End 31-DEC-2006 Summary: (provided by applicant): Osteoarthritis (OA), the leading cause of disability in the United States, has a significant impact on quality of life. Knee OA alone affects approximately 6% of the US adult population. In patients with severe knee OA total joint replacement JJR) surgery is considered an extremely valuable intervention, which relieves chronic pain, restores lost function, and is cost effective. Recent reports, however, indicated that TJR may be underutilized and that utilization varies widely by race/ethnicity and gender. For instance, women have significantly worse preoperative functional status at time of TJR for OA, suggesting they choose TJR at a more advanced disease stage, possibly at the expense of quality of life. To date, findings to explain these disparities are inconclusive, but our preliminary data supports the view that differences in the amount of perceived social support may contribute to the different utilization patterns. Based on results of our pilot studies, we hypothesize that social support may be critical in understanding race/ethnicity and gender differences in TJR rates. Specifically, 1) prior to surgery, perceived and actual social support affect TJR acceptance rates differently and this difference varies by race/ethnicity and gender, and 2) more perceived social support is related to less self-reported disease severity, which ultimately affects the TJR acceptance rates. We will conduct a prospective longitudinal study of 320 subjects with severe knee OA who are TJR candidates to establish measures of social support, disease activity, and functional status. This team will use results from the proposed study to generate a future longitudinal study to aid in developing an intervention to promote earlier clinical treatment for those individuals who are prone to wait until more advanced stages of disease before considering TJR. The results of such a study could be applied to the understanding and treatment of other chronic conditions. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: POSTMENOPAUSAL HORMONE REPLACEMENT THERAPY AFTER CABG Principal Investigator & Institution: Ouyang, Pamela C.; Associate Professor of Medicine; Medicine; Johns Hopkins University 3400 N Charles St Baltimore, MD 21218 Timing: Fiscal Year 2001; Project Start 15-AUG-1996; Project End 31-JUL-2004 Summary: Coronary atherosclerosis is a major cause of death in women in the USA. Although coronary artery bypass surgery decreases symptomatic and clinical evidence of ischemia, it does not alter the underlying process. Patients may present several years later with recurrent symptoms that may be a result of occlusion of saphenous vein grafts, development of atherosclerotic disease in the vein grafts, or progression of underlying disease. Any intervention that can reduce the rate of progression of coronary atherosclerosis following bypass surgery would provide significant benefit for women following bypass surgery and possibly for other women with atherosclerotic disease.
46 Surgery
Observational studies suggest that postmenopausal estrogen replacement therapy is associated with a reduction in cardiac morbidity. However the benefit for hormone replacement therapy in women with established coronary disease has not been demonstrated. This randomized, double-blind controlled trial tests the hypothesis that postmenopausal hormone replacement therapy in women following coronary bypass surgery will reduce the occurrence of graft occlusion and delay the development of graft atherosclerosis. Women will be randomized to esnadiol with daily medroxyprogesterone or placebo within 4 weeks of bypass surgery. Graft occlusion and development of vein graft atherosclerosis will be measured by comparing quantitative coronary angiographic and intravascular ultrasonographic assessment of disease severity and extent performed at 6 months and 3.5 years after randomization. The primary outcome variables will be the occurrence of graft occlusion at 6 months and the change in severity and extent of atherosclerosis in the saphenous vein grafts over 3 years. The proposal will determine th influence of hormone replacement therapy on the primary outcome variables. The pathophysiologic mechanisms of interest in this proposal are platelet activation, fibrinogen binding to platelets, vascular reactivity, coagulation and fibrinolytic factors and lipoprotein composition. The proposal will test the hypothesis that these variables predict the occurrence of graft occlusion and rate o development of graft atherosclerosis. The proposal also tests the hypothesis that hormone replacement therapy exerts its beneficial effects by its effects on those risk factors in addition to more traditional risk factors including the lipids and lipoprotein profile.

Project Title: PRECONDITIONING IN OPEN HEART SURGERY Principal Investigator & Institution: Maulik, Nilanjana; Associate Professor; Surgery; University of Connecticut Sch of Med/Dnt Bb20, Mc 2806 Farmington, CT 060302806 Timing: Fiscal Year 2001; Project Start 01-FEB-1998; Project End 31-JAN-2003 Summary: (Investigator's abstract): "Myocardial preconditioning is believed to be the state of the art protective technique against ischemic injury. However, Preconditioning has not been applied in conjunction with open heart surgery. The mechanism of preconditioning is also not known. The proposed research will examine the mechanism of preconditioning and attempt to develop preconditioning modalities to salvage arrested heart during open heart surgery. The biochemical pathways activated by the preconditioning phenomenon and the molecular mechanism(s) of the gene expression will be studied. Hearts from the anesthetized rats and rabbits will be excised for isolated perfused heart preparation. To induce ischemic preconditioning, isolated hearts will be made globally ischemic for 5 minutes followed by 10 minutes of reperfusion. The process will be repeated four times. The hearts will then be made ischemic for 30 minutes followed by 60 minutes of reperfusion. To test our hypothesis that preconditioning occurs by tyrosine kinase receptor activation, we will use a tyrosine kinase blocker to inhibit preconditioning. To further explore whether the intracellular signaling occurs through tyrosine kinase-phospholipase D-protein kinase pathway, antiphospholipase D antibody will be used to inhibit phospholipase D activation associated with preconditioning. Activation of protein C kinase and its upstream regulators MAP kinase and MAPKAP kinase will be examined simultaneously. Biopsies and perfusate samples will be used to measure biochemical parameters which will include quantification of phospholipase C and D, diacyl glycerol, phosphatidic acid, protein kinase C, MAP kinase and MAPKAP kinase 2. The cellular injury will be monitored biochemically by measuring the LDH and CK releases. Functionally, both left

ventricular systolic and diastolic functional parameters will be continuously monitored on a beat to beat basis. These will include the left ventricular stroke work, elastance, and the time constant of isovolumic relaxation. Induction for the expression of stress-related genes will be studied by Differential Display Technique. The results of this study will not only enable us to understand whether tyrosine kinase-phospholipase D-protein C kinase-MAP kinase-MAPKAP kinase 2 signaling pathway is involved in preconditioning, but also will determine whether preconditioning occurs at the molecular level by reprogramming the gene expression. The results will be useful to develop treatment modalities for preconditioning the heart during open heart surgery." Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: PREDICTORS OF OUTCOME IN COLORECTAL CANCER Principal Investigator & Institution: Meyerhardt, Jeffrey A.; Dana-Farber Cancer Institute 44 Binney St Boston, MA 02115 Timing: Fiscal Year 2003; Project Start 01-AUG-2003; Project End 31-JUL-2008 Summary: (provided by applicant): In 2001, approximately 135,400 Americans are expected to develop colorectal cancer, and 56,700 individuals will die from the disease. Though 80% of patients present at a stage when all apparent diseased tissue can be surgically resected, up to 40% of these patients will suffer from recurrence. Depth of tumor invasion and nodal status are considered the most important predictors of recurrence, and are the primary factors used by clinicians in recommending to patients adjuvant therapy after surgery. However, there is considerable variation in the outcome of patients with colorectal cancer not explained by traditional prognostic factors. The candidate for this award will utilize databases from two large, randomized adjuvant therapy trials to study other prognostic factors on outcomes in colon and rectal cancer. Specifically, these databases provide an opportunity to study the influence of potential modifiable treatment and patient characteristics on short- and long-term outcomes in patients with potentially curable colon and rectal cancers treated with surgery and adjuvant therapy. The specific aims of this proposal are (1) to examine whether hospital surgical volume and hospital characteristics affect cancer recurrence, overall survival, and treatment-related toxicity in patients undergoing curative surgery and adjuvant therapy for stages II and III rectal cancer, and (2) to examine the impact of diet and lifestyle on colon cancer recurrence and survival. Completion of these projects will improve our understanding of how potentially modifiable factors affect outcomes in patients treated with curative surgery and standard adjuvant therapy. These projects will provide insight into dietary and lifestyle behaviors of patients with colon cancer and which behaviors impact outcomes. Finally, these projects will allow the candidate to gain invaluable experience in database analysis and clinical epidemiologic and health outcomes research. The candidate will complete a Masters in Public Health (MPH) degree and advanced courses at the Harvard School of Public Health during the first two years of the proposed award. The projects will be performed under the mentorship of Dr. Charles Fuchs, a well-established researcher in prevention and health services research. At the completion of the project, the candidate will have gained the experience to become an independent researcher in clinical epidemiologic and health outcomes research.

Project Title: PRESURGERY HYPNOSIS--BENEFITS ANALYSIS IN BREAST CANCER Principal Investigator & Institution: Montgomery, Guy; Ruttenberg Cancer Center; Mount Sinai School of Medicine of Nyu of New York University New York, NY 10029 Timing: Fiscal Year 2001; Project Start 17-AUG-2001; Project End 31-JUL-2004 Summary: Over 90% of the 184,000 women diagnosed with breast cancer in 2000 will undergo surgery as part of their curative treatment. Despite improvements in pharmacological management, surgical procedures under general anesthesia continue to be associated with clinically significant side effects, chief among which are pain and nausea. These clinical problems are particularly severe following surgical treatment for breast cancer and can require additional pharmacologic intervention, prolong recovery room stay, delay discharge, and lead to unanticipated readmission. Clinical research with other surgical populations has indicated that hypnosis can reduce intraoperative complications, reduce postoperative symptoms and enhance recovery (e.g., reduce pain, nausea, hospital stays), however, the treatment efficacy of hypnotic techniques with breast cancer surgical patients has yet to be established. A separate line of previous clinical research with surgery populations has indicated that preoperative psychological factors (emotional distress and cognitive expectations) are predictive of patients' postoperative experiences of side effects, but again research on breast cancer surgical patients is scant. The proposed research will bridge the two previous lines of research by combining a randomized clinical trial, (in which the effects of a preoperative hypnosis intervention to control side effects are compared to attention control), with a prospective quasi-naturalistic study, (in which the relations between preoperative psychological factors and patients' reactions to surgery are examined). In addition to establishing the applicability to breast cancer patients of findings in the general psychological, hypnosis and surgical literatures, the goal of proposed study is to make novel theoretical contribution by examining the potential role of psychological factors as the "active ingredients" in the beneficial effects of hypnosis. The proposed study will also make a novel practical contribution by examining cost-effectiveness of the hypnosis intervention, an approach which may have compelling implications for clinical practice as well as future behavioral research. The Specific Aims of the study are: 1) To investigate the impact of a presurgical hypnosis intervention on women scheduled for surgical treatment for breast cancer; 2) To investigate the contribution of preoperative emotional distress, and cognitive expectations to post- surgery side effects and recovery; 3) To determine whether the beneficial effects of the hypnosis intervention are accounted for (mediated) by differences in presurgery cognitive expectations and emotional distress; and 4) To investigate the cost-effectiveness of the presurgical hypnosis invention. o achieve these aims, 140 breast cancer patients scheduled for mastectomy will be randomly assigned to a hypnosis intervention group or an attention control group. The impact of the hypnosis intervention on postoperative nausea, pain, recovery from surgery, and cost- effectiveness will be analyzed within an experimental study design. The influence of presurgery distress and expectations of side effects will be analyzed within quasi-naturalistic study designs. The possible mediational role of these factors in hypnosis effects will be examined will classic statistical approaches. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: PRESURGICAL STRESS REDUCTION MENTAL HEALTH AND CANCER Principal Investigator & Institution: Cohen, Lorenzo; Associate Professor; Behavioral Science; University of Texas Md Anderson Can Ctr Cancer Center Houston, TX 77030
Studies 49
Timing: Fiscal Year 2001; Project Start 01-AUG-1998; Project End 31-JUL-2003 Summary: Stress associated with a life threatening illness contributes to poor adjustment and psychological and physiological consequences harmful to adaptation and recovery from surgical treatment. Cancer and its treatment are associated with considerable distress, impaired quality of life, poor mental health, and reduced physical function. This is particularly true for men with prostate cancer undergoing a radical prostatectomy (RP), the surgical treatment of prostate cancer. Recovery from RP is often associated with urinary and sexual dysfunction in addition to more common sources of stress associated with surgery. At least 50 percent of RP patients have permanent impotence and many experience prolonged periods of urinary incontinence. In addition to the distress associated with these quality of life changes, prostate cancer patients face the fear of recurrence, progression, and death. Recent research has found that psychosocial and psychoeducational interventions can increase quality of life and mental health of cancer patients, and may also improve immune status, pain indices, hospital costs, and length of survival. Despite the dramatic increase in research on psychosocial aspects of cancer and of interventions for cancer patients, relatively little work has considered prostate cancer or the specific impact of surgery for cancer. The proposed study will randomly assign prostate cancer patients undergoing RP to a presurgical stress management group, an attention control group, or a usual care control group. Dimensions of response to surgery and recovery will include measures of mental health and psychological status, quality of life, and immune, endocrine, and cardiovascular function, as well as pain, use of analgesic medication, and length of hospital stay post- surgery. This design will allow characterization of distress associated with prostate cancer and RP and examination of psychological, physiological, and quality of life changes associated with surgery and short- and long-term recovery. We will also evaluate a theoretical model developed to examine dispositional and environmental factors as predictors of response to surgery and long-term recovery. We hypothesize that pre-surgical stress management will reduce the negative impact of RP assessed by psychological, physiological, and quality of life measures.

Project Title: QUANTITATIVE IMAGING & TREATMENT WITH FOCUSED ULTRASOUND Principal Investigator & Institution: Sanghvi, Narendra T.; President; Interscience Research, Inc. 3940 Pendleton Way Indianapolis, IN 46226 Timing: Fiscal Year 2001; Project Start 01-FEB-1999; Project End 31-MAR-2003 Summary: (Verbatim from Applicant's Abstract): A vital component of a successful clinical application of HIFU surgery is an accurate assessment of the treated tissue volume. It would be most beneficial if the HIFU-created lesion could be visualized and controlled in real-time so that treatment protocols could be modified to accommodate local and variable conditions in individual patients. The goal of this proposal is to upgrade the Sonablate device that would guide and control HIFU surgery by analyzing backscattered ultrasound signals. In our Phase I in vitro studies, several signal processing algorithms were successfully developed that measured changes in tissue parameters due to HIFU exposures. In this Phase II application, we propose (1) to utilize the signal processing algorithms developed in Phase I to separate the effects of cavitation and heat during HIFU surgery, (2) to perform a series of in vitro experiments to validate our signal and image processing algorithms, (3) to modify the Sonablate device to incorporate these lesion-imaging and control algorithms in real time, (4) to perform a series of in vivo experiments in animals with the modified Sonablate that
50 Surgery
would test the effectiveness of these algorithms, and (5) to perform a human feasibility study based on safe and efficacious results from the animal studies. PROPOSED COMMERCIAL APPLICATION: Prostate cancer is becoming an ever-more-frequent malady for man. Current annual market for treatment of prostate cancer in the United States is estimated around $5 billion. Currently, Focus Surgery Inc. manufactures the Sonablate TM system, which makes use of HIFU technology to treat benign prostatic hyperplasia (BPH). To extend the application of this system to treat prostate cancer, a reliable non-invasive feedback mechanism is necessary. The current proposal directly addresses this challenge. Successful completion of this project will open the enormous market of prostate cancer treatment for our Sonablate TM device. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: RACE,TREATMENT AND ENDOMETRIAL CANCER SURVIVAL Principal Investigator & Institution: Armstrong, Katrina; Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, PA 19104 Timing: Fiscal Year 2003; Project Start 11-APR-2003; Project End 31-MAR-2006 Summary: (provided by investigator): Survival after the diagnosis of endometrial cancer varies significantly between African-American and Caucasian women. Between 1992 and 1998, five-year survival for African-American women after endometrial cancer diagnosis was 58.9%, compared to 85.8% for Caucasian women. The disparity in survival is greatest among older women, with an absolute difference in five year survival of 10% for women under 50 compared to 30% for women 50 years of age and older. Prior studies have identified several factors that contribute to the observed racial disparity in endometrial cancer survival, including stage at diagnosis and tumor grade. However, significant differences in survival between Caucasian and African-American women persist even after adjusting for these factors. There are several reasons to believe that differences in the prevalence and characteristics of treatment may contribute to this residual survival disparity. African- Americans have been shown to be less likely to undergo definitive treatment for many different medical and surgical conditions. Characteristics of treatment (including provider characteristics, hospital characteristics and intensity of therapy) are associated with outcome for other surgical conditions, including surgery for lung, pancreatic and breast cancer. Understanding the prevalence and outcomes of differences in treatment characteristics between African-American and Caucasian women offers a potentially promising new approach to improving endometrial cancer survival among African-American women. In this application we propose to use SEER-Medicare linked data to examine the outcomes of AfricanAmerican and Caucasian women diagnosed with endometrial cancer between 1991 and 1999. The primary outcome will be overall and disease-specific survival times (which may be censored) as assessed by Medicare vital statistics and SEER linkage to the National Death Index respectively. Analyses will adjust for comorbidity, socioeconomic status and tumor characteristics using information provided in the SEER-Medicare database. Provider and hospital characteristics will be determined by linkage to the AMA practitioner database and AHA annual survey respectively. Our three specific aims explore the contribution of differences in treatment to the higher mortality among African-American women diagnosed with endometrial cancer. We group differences in treatment into three categories: (1) differences in the rates of treatment; (2) differences in the extent/intensity of treatment; and (3) differences in the providers and hospitals/facilities who deliver the treatment. For each category, we will explore differences between African-American and Caucasian women, their association with outcome, and to what extent variations in treatment explain the excess mortality among

African-American women. In addition, within each category, we will investigate differences related to primary surgery and adjuvant radiation therapy. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: RADIOTHERAPY--PREVENT LAMINECTOMY
FIBROSIS
AFTER
LUMBAR
Principal Investigator & Institution: Gerszten, Peter C.; Neurological Surgery; University of Pittsburgh at Pittsburgh 350 Thackeray Hall Pittsburgh, PA 15260 Timing: Fiscal Year 2001; Project Start 30-SEP-2000; Project End 31-JUL-2003 Summary: Perineural scar formation, also known as peridural fibrosis, is a common occurrence after lumbar discectomy surgery. Peridural fibrosis can cause compression or tethering of the nerve root and has been implicated in recurrent radicular and/or low back pain after a lumbar discectomy. Fibrosis may be the underlying cause in as many as a quarter of all failed back surgery syndrome cases. Reoperation with the intention of excising this fibrous tissue often produces a poor surgical result and further scarring. Furthermore, a large variety of materials have been implanted onto the dura in animal models with the goal of preventing perineural fibrosis with only modest success. Low dose radiation has long been known to inhibit fibroblast and osteoblast activity. Perioperative radiation therapy has been demonstrated to be a useful method to prevent both keloid and heterotopic bone formation in human trials. Radiation has not previously been studied as a means to inhibit peridural fibrosis. Our previous studies investigating in both rat and dog models showed a significant reduction in peridural fibrosis after laminectomy using low dose external beam radiation (700 cGy) given 24 hours prior to surgery. Based on these preliminary data, we will test the hypotheses that (1) preoperative low dose external beam radiation given 24 hours prior to surgery will decrease the amount of peridural fibrosis in humans, and (2) this reduction in peridural fibrosis will lead to an improvement in patient outcome. For this study, patients will be enrolled in a randomized double-blinded controlled clinical investigation either to preoperative radiation (treatment group) or no preoperative radiation (control group) prior to surgery. Patients will be followed at 1, 3, 6, and 12 months with self- report instruments of function, measures of impairment, and magnetic resonance imaging. As more than 10,000 patients per year in the United States have failed back surgery syndrome thought secondary to peridural fibrosis, this novel treatment strategy would be efficacious to a large number of patients with this disease process.

Project Title: RISK FACTORS FOR VENOUS THROMBOEMBOLISM IN THE COMMUNITY Principal Investigator & Institution: Heit, John A.; Professor; Mayo Clinic Rochester 200 1St St Sw Rochester, MN 55905 Timing: Fiscal Year 2001; Project Start 01-APR-2001; Project End 31-MAR-2005 Summary: This is a study of genetic and environmental determinants of venous thromboembolism (VTE) in the Rochester Minnesota Olmsted County population. The specific aims of the study are: 1) to update the 1966-95 inception cohort to include Olmsted County residents with VTE during the five year period, 1996-2000; 2) to extend the analysis of risk factors for VTE by identifying two Olmsted County residents (controls) without VTE matched by age and gender to each definite or probable case within the 1996-2000 cohort, and to obtain plasma and genomic DNA from all cases and controls and perform a case-control study to test the hypothesis that first specific
52 Surgery
diseases are related to VTE and mutations of the factor five and prothrombin are independent risk factors for VTE in the community; and interactions between environmental and genetic factors. They will determine the population attributable risk for VTE associated with each risk factor, both individually and collectively for all significant risk factors. They will then compare two Olmsted County residents who received major surgery without developing VTE matched by date and type of surgery to a case with VTE within three months after surgery in order to look at risk factors related to surgery and genetic markers. They will do a similar analysis this time using two Olmsted County residents who were hospitalized for medical illness without developing VTE matched by gender and date of hospitalization to a case who developed VTE within three months after hospitalization and perform a case-control study to test the hypothesis again that risk factors and genetic markers are associated with elevation of risk of VTE. Finally, the investigators will plan to extend their analysis of current VTE in relationship to use of standard heparin and low molecular weight heparin.

Project Title: ROLE OF COAGULATION SYSTEM VARIABILITY: CARDIAC SURGERY Principal Investigator & Institution: Donahue, Brian S.; Anesthesiology; Vanderbilt University 3319 West End Ave. Nashville, TN 372036917 Timing: Fiscal Year 2002; Project Start 07-JAN-2002; Project End 31-DEC-2006 Summary: (provided by applicant): Hemostatic complications of cardiac surgery often occur for reasons that are not well understood. Despite efforts to limit blood loss and blood product transfusion, cardiac surgery patients consume 10-20% of the nation?s blood supply. Postoperative thrombotic events, such as coronary graft occlusion, are often unpredictable, and cause appreciable morbidity, resource utilization, such as need for additional revascularization. Many risk factors for these complications have been identified; among these, it is known that activation of the coagulation system occurs during cardiopulmonary bypass (CPB) and is responsible for mediating substantial postoperative hemostatic impairment. Although contact system activation unquestionably occurs during CPB, the role of the extrinsic system has not been characterized. Extrinsic system activation does occur on CPB, and may be the major contributor to thrombin generation. Furthermore, genetic variants within the genes for tissue factor, factor VII, and tissue factor pathway inhibitor have been described, and many of these significantly influence the activity of their respective protein gene products. However, the impact of these polymorphisms in contributing toward extrinsic system activation during CPB is undescribed. The overall goal of this study is to evaluate the contribution of extrinsic system variation toward observed variability in thrombin generation and impairment of hemostasis following CPB, and identify specific genetic variants in the extrinsic system that may place patients at increased risk for coagulation system abnormalities following CPB. This understanding will assist clinicians in identifying cardiac surgery patients at increased risk for hemostatic abnormalities, and target novel therapies toward those patients most likely to benefit. The project will make extensive use of data in the Vanderbilt Cardiac Surgery Registry, a valuable database of genetic and clinical data presently being prospectively collected on elective adult cardiac surgery patients.

Project Title: SURGERY
SENSORY
RE-TRAINING
FOLLOWING
ORTHOGNATHIC
Principal Investigator & Institution: Phillips, Ceib L.; Research Professor; Orthodontics; University of North Carolina Chapel Hill Office of Sponsored Research Chapel Hill, NC 27599 Timing: Fiscal Year 2001; Project Start 15-JUL-2001; Project End 31-MAY-2006 Summary: (provided by the applicant) Abnormal facial sensation has a negative impact on patient's oral behaviors and may adversely affect a patient's quality of life if the altered sensation persists. Many patients with abnormal sensations retain some sensory function and do not develop chronic pain, and for those individuals there are no currently evidence-based noninvasive therapies. The goal of this project is to evaluate sensory re-training, a rehabilitative therapy that offers significant potential for patients who experience impaired sensory function regardless of the cause. This behavior therapy approach has been used with substantial clinical success with hand injury patients since the 1970s. Re-training appears to enhance central reorganization of the impulses from an injured sensory nerve to the cerebral cortex so that the altered sensory signals can be interpreted and translated into functionally meaningful motor functions. Sensory re-training will be compared to a placebo jaw-opening exercise in a single blind, randomized two-arm parallel group stratified block clinical trial, using orthognathic surgery patients as subjects. Orthognathic surgery patients offer an uncompromised model for the evaluation of new rehabilitative therapies. These healthy patients, treated to correct dentofacial deformity, present for surgery with no neurosensory impairment, but yet routinely experience substantial alterations in facial sensation following the surgical procedure. The effcts of sensory re-training will be evaluated using three types of outcomes: patient-centered measures to assess the magnitude of the negative effect of altered sensation after surgery and the recovery time needed to reach little or no negative effect; neurosensory behavior measures to assess the patient's ability to learn alternate cues for touch perception and discrimination; and a conventional neurosensory contact threshold measure to assess the actual deficit. Our primary focus will be on the patient's perception of the negative impact of altered sensation on daily life. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: SIXTH INTERNATIONAL MARFAN SYNDROME SYMPOSIUM Principal Investigator & Institution: Byers, Peter H.; Professor; Pathology; University of Washington Seattle, WA 98195 Timing: Fiscal Year 2001; Project Start 10-AUG-2001; Project End 31-JUL-2002 Summary: (provided by applicant): The Sixth International Marfan Syndrome Symposium will be held in Seattle, WA from August 11 -14, 2001. This meeting will bring together investigators who represent the most advanced research directed toward determining the underlying basis of Marfan Syndrome, the fundamental biology of the fibrillin genes and their interacting partners, the identification of other matrix components that are important for the construction of the elastic fiber network, the mechanisms by which the mutations are translated into the phenotypic findings, the issues of locus heterogeneity and the relationship to other disorders that result from mutations in related genes, the natural history of the disorder, the change in natural history by medical or surgical intervention, and the manner in which analysis of these genes assist in clinical decision making. The theme of the Symposium will be "Current Controversies in Research in Pathogenesis and Treatment of Marfan Syndrome and Related Disorders". These issues will be examined in five scientific sessions of
54 Surgery
approximately 3 to 3.5 hours each. The first session will be devoted to the relationship of genotype to phenotype, the role of molecular diagnostics, and the effect of mutations on the fibrillin proteins. The second will examine the function of fibrillitts, the cell biology of the proteins, their processing and fibrillogenesis, and interaction with other components of the matrix, and how defects in these processes lead to Marfan and other phenotypes. The third will examine the organization of tissues, the tole of fibrillins in non-Marfan phenotypes, and of other disorders that may mimic some of the Marfan phenotypes. The fourth will be devoted to issues in medical therapy, including the use of P-blockers, calcium channel blockers, and inhibitors of matrix degradation to slow the rate of aortic enlargement, the major risk factor for premature death. The fifth will examine issues surrounding cardiac surgery and surgery for lens dislocation. These issues include the use of "valve-sparing" surgery in aortic foot replacement, the timing of aortic surgery, and the role of lens removal for treatment of visual disturbance. This will be the first major gathering of investigators in three years and will be held in conjunction with the National Marfan Foundation annual meeting. The expected 125 participants should galvanize research efforts for the next years. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: SOFTWARE TOOLKIT FOR IMAGE GUIDED SURGERY Principal Investigator & Institution: Cleary, Kevin R.; Associate Professor; Kitware, Inc. 469 Clifton Corporate Pky Clifton Park, NY 12065 Timing: Fiscal Year 2003; Project Start 15-MAY-2003; Project End 31-OCT-2004 Summary: (provided by applicant): This Phase I STTR application represents a partnership between a university-based research group (Imaging Science and Information Systems [ISIS] Center, Department of Radiology, Georgetown University) and a small business specializing in open-source software development (Kitware, Inc. of Clifton Park, NY). Over the past 1 1/2years, the ISIS Center has been developing a prototype image-guided surgery system called IGBiopsy to enhance the precision of instrument placement for minimally invasive abdominal interventions. This system incorporates a soon-to-be commercially available magnetic tracking system and specially designed needles whose tip position can be monitored. The software for this prototype is based on the Visualization Toolkit (VTK), an open-source software system developed and now supported by Kitware. This prototype software and hardware will be used as the starting point for the work proposed here. The specific aims are: 1. Integration. As a demonstration project, we will integrate the graphical user interface for image-guided abdominal interventions developed by Georgetown with the Insight Registration and Segmentation toolkit (ITK) developed by Kitware and others. 2. Preclinical evaluation. The software developed in Aim 1 will be evaluated in a pre-clinical study using a liver respiratory motion phantom already developed by Georgetown. The accuracy of the system in assisting the physician in placing a biopsy needle into a simulated liver lesion will be evaluated. These tests and Specific Aim 3 will also be used to evaluate the accuracy of the magnetic tracking hardware in the interventional suite. 3. Clinical evaluation. The system will be further evaluated using a cadaver study in the interventional suite. The accuracy of the system in assisting the physician in targeting selected points in the liver will be evaluated. If the Phase I work proposed here is successful, Kitware and Georgetown University will be in a position to develop an opensource software framework for image-guided surgery in a Phase II effort.

Project Title: SOLID STATE BETA IMAGING SENSOR FOR IMAGE GUIDED SURGERY Principal Investigator & Institution: Entine, Gerald; President; Radiation Monitoring Devices, Inc. 44 Hunt St Watertown, MA 02472 Timing: Fiscal Year 2002; Project Start 01-AUG-2002; Project End 31-JUL-2004 Summary: (provided by applicant): Nuclear Medicine imaging has been widely used to preoperatively image structures of interest for excisional biopsy. Radio-guided intraoperative procedures utilizing radiotracers have facilitated a cost-effective, highly specific means to locate suspect tissue and access it for pathologic analysis. The result of radio-guided surgery is increased tissue specificity obtained for biopsy, minimally accessed incisions, and the reduction of inpatient hospital utilization with an improved patient recovery. Nuclear medicine based surgical guidance with non-imaging gamma detector probes is gaining in acceptance and popularity. The main drawback of nonimaging guidance is the lack of ancillary information of the surveyed area, such as distinction between two neighboring radioactive regions, which can be overcome with an intraoperative imaging probe. Also, the highly penetrating gamma radiation arising from other parts of the body increases the background and limits the practical use of these probes. We propose to address these limitations by designing a new-generation intraoperative probe intended to rapidly image the tumor bed with short-range beta rays. This new design will be based on a solid-state, compact readout sensor coupled to a high resolution, high SNR converter. When developed, this detector will allow accurate delineation of the tumor, thus facilitating precise resection. PROPOSED COMMERCIAL APPLICATIONS: Advances in radiopharmaceuticals has dramatically escalated the use of intraoperative probes in surgery. The proposed research will provide a new class of digital imaging probes, which will exploit these advances allowing for complete and accurate tumor resection with enhanced quality of health care and increased lifespan of patients. This new imaging technology has enormous potential in both medical and non-medical applications. The estimated market size for probes is well over a hundred million dollars. A significant fraction of this market represents areas where the proposed technology will have a major impact. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: SPASTICITY AND STRENGTH AS INDICATORS FOR RHIZOTOMY Principal Investigator & Institution: Engsberg, Jack R.; Associate Professor; BarnesJewish Hospital Ms 90-94-212 St. Louis, MO 63110 Timing: Fiscal Year 2001; Project Start 15-AUG-1997; Project End 31-JUL-2002 Summary: (Adapted from the Applicant's Abstract): The long term goal is to improve function in children with cerebral palsy (CP). A selective dorsal rhizotomy (SDR) is performed to improve function by minimizing spasticity. A contraindication and limitation of the SDR is muscle weakness. Muscle weakness is related to reduced function. Thus, determining the degree of spasticity and strength/weakness in a child is a key consideration in the SDR selection process. Objective measures to assess spasticity and strength are not presently used in the process. In this study, objective measures to quantify spasticity and strength will be utilized to determine relationships between presurgery spasticity and strength and post-surgery functional measures. Based upon these relationships, an objective clinical tool to improve the selection of SDR candidates will be developed. In addition, comparisons of the measures among 4 different groups of children (n=40/group) will be made, those: 1) undergoing a SDR (SDR group), 2) undergoing physical therapy (PT) identical to the SDR group (PT group), 3) undergoing
56 Surgery
no change in current intervention (CP controls) and 4) having able bodies (AB controls). Specific Aim 1: Evaluate the importance of pre-surgery spasticity and strength as predictors of functional change due to SDR. Children from the SDR group will be tested on a dynamometer for spasticity and strength, evaluated using the Gross Motor Function Measure, have a gait analysis performed and answer a disability questionnaire. These assessments will be made 6 weeks and again 2 days prior to surgery, and at 8 and 20 months post surgery. Stepwise multiple regression with repeated measures will test the hypothesis that composite pre-surgery spasticity and strength from the ankles, knees, and hips in the SDR group will predict functional changes as a result of the SDR. Specific Aim 2: Compare impairment and functional measures among the SDR group, PT group and CP controls. The same assessments and testing sequence as the SDR group will be followed for these groups, but no surgery will be performed. ANOVA and ANCOVA will test the null hypotheses that the 3 CP groups will not change in impairment and function over all sessions and will not be different from one another. Specific Aim 3: Compare impairment and functional measures from 3 CP groups with those from AB controls. The children with able bodies will be assessed for spasticity, strength, and gait. ANOVA will test the null hypothesis that the CP groups will not be significantly different from the AB controls across all sessions. Descriptive statistics will describe the extent of differences from AP controls. The intent is that this investigation will improve the current methods for selecting SDR patients, thereby improving patient outcomes and reducing costs. It will also compare the efficacy of 3 modes of treatment for CP: SDR with intensive PT, intensive PT without SDR, and standard intervention.

Project Title: STUDY OF WOMEN WITH CONGENITAL ADRENAL HYPERPLASIA Principal Investigator & Institution: Migeon, Claude J.; Professor; Pediatrics; Johns Hopkins University 3400 N Charles St Baltimore, MD 21218 Timing: Fiscal Year 2001; Project Start 13-APR-2001; Project End 31-MAR-2005 Summary: (Adapted from the Investigator's Description): The principle goal of this study is to document long-term psychosexual development as it relates to excess androgen exposure during pre- and postnatal development in women with Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency. Additionally, the investigators plan to study the impact of genital surgery on psychosexual development in CAH women. Participants include 150 CAH women over 18 years of age. Comparison subjects include 50 unaffected female siblings or first cousins of CAH participants and 50 patients with polycystic ovary disease (PCO). The specific aims are as follows: (1) determine degree of androgen exposure at various developmental stages in women with CAH, (2) identify factors such as timing and type of genital surgery that influence psychosexual development in women with CAH, (3) assess psychosexual development in women with CAH and (4) investigate relationships between degree of androgen exposure, timing of androgen exposure and genital surgery with psychosexual development in women with CAH. Knowledge gained from this investigation will contribute to our understanding of androgenic influences on individual differences in development and expression of cognitive and sexual behaviors. Furthermore, information obtained from this study will contribute to improved medical and surgical treatment of CAH women. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen

Project Title: SUBTLE DISTURBANCES OF COBALAMIN STATUS Principal Investigator & Institution: Carmel, Ralph; Director of Research; New York Methodist Hospital 506 60Th St New York, NY 11215 Timing: Fiscal Year 2003; Project Start 01-SEP-1983; Project End 31-MAY-2008 Summary: (provided by applicant): Low cobalamin (vitamin B12) levels are frequent, especially in the elderly, several million of whom are affected. Most often the low levels reflect "subclinical cobalamin deficiency", an asymptomatic state marked only by metabolic evidence of cobalamin insufficiency. It is unclear if these persons need intervention because progression to clinical deficiency may be uncommon, and many people with low levels have no deficiency at all. The proposal aims to study whether nitrous oxide (N2O), used in most general anesthesia in the US, worsens cobalamin status in elderly people who have unrecognized subclinical cobalamin deficiency. The reason for concern is that N2O inactivates cobalamin and therefore can cause neurological dysfunction in some patients with underlying clinically expressed cobalamin deficiency. The elderly are known to have an increased risk of postoperative cognitive complications. The study will recruit patients >60 years old who are scheduled for elective surgery in which N2O use for more than 1 hour is planned. Patients will be randomized in a blinded fashion to receive a standard anesthetic regimen of several agents, in which N2O is either included or replaced by air; the two regimens are equally safe and effective. They will undergo cognitive function and depression scale testing, blood testing of cobalamin-related metabolism, and clinical evaluation before surgery and at 48 hours, 14 days and 28 days after surgery. Those with cognitive changes will be treated with cobalamin and reevaluated after 3 months. Statistical analysis will compare the subgroups' metabolic, neuropsychological, demographic, genetic and clinical data. The primary question is what effect routine N2O anesthesia has on metabolic and clinical status related to subclinical cobalamin deficiency. It will also resolve whether or not the combination of N2O and the deficiency can explain the increased rate of postoperative cognitive problems in the elderly, and thus if preoperative or postoperative attention to cobalamin is needed in the elderly. A secondary goal is to extensively study cobalamin-related and homocysteine-related metabolism in these patients and their conditions, particularly as changes evolve after N2O use and later improvement. The clinical study provides a unique opportunity to establish these metabolic details and to compare their interactions with common genetic mutations in the patients that affect enzymes relevant to cobalamin deficiency, N2O effects, and their contribution to the clinical outcomes.

The Committee has designated "disease-specific" program representatives (breast, colorectal, hepatic, and thoracic) from the Research Base. A newsletter has enhanced pre- and post-meeting communications. Future efforts will focus on developing a Liaison Program to enhance "disease- specific" community surgeon representation and a Direct Tailored Communication Network. 2) Scientific
58 Surgery
Contributions-Surgeons were listed as study chair (13) or co-chair (6) for a total of 19 diverse protocols in the last grant cycle, (5) Colorectal, (6) Hepatic Metastases Metastases, (2); Thoracic, (5); and Melanoma, (1). In the Breast Program, there are two protocols specifically addressing surgical questions: N9431 investigates the association between menstrual cycle phase, breast addressing surgical questions: N9431 investigates the association between menstrual cycle phase, breast cancer surgery, and disease-free survival. E5194 investigates results from local excision along for selected patients with ductal carcinoma in situ. 954-32-51 is a phase II follow-up study to the pilot studying Accelerated Hyperfractionated Radiation Therapy Following Lumpectomy and Axillary Lymph Node Dissection in Patients with Stage I/II Breast Cancer. Future plans include investigations into bone marrow analysis in breast cancer and how information on micrometastases can be used for staging and treatment. In the Colorectal Program, surgeons are study chairs on four protocols, two of which investigate independent surgical questions; 93-46-53(INT -0146) represents a unique effort to address whether laparoscopic surgery for colon cancer is oncologically is oncologically sound. 97-46-52 addresses the issue of surgeon variability in rectal cancer surgery in a communitybased USA practice. Future plans include additional adjuvant studies incorporating CTP-11 and 5-FU based chemotherapy, C89803. The Hepatic Metastases Program includes two important studies, 90-46-52 and 92-46-52, testing the role of adjuvant therapy and testing the ability to extend curative resections to patients with multiple metastases using systemic plus regional chemotherapy, respectively. A future study, 9746- 51, will study the possibility of rendering otherwise "unresectable" lesions "resectable" employing systemic oxaliplatin, 5-FU, and CF chemotherapy The Thoracic Program within surgery is new and promises to become active with esophageal and lung-protocols. Although most of these test surgical adjuvant therapies, one current protocol, C9334 (CALGB initiated), investigates a surgical question, whether Sclerosis of Pleural Effusions by Talc Thoracoscopy is good as Talc Slurry. NCCTG's success with 95-24-51, a phase II trial of preoperative paclitaxel and carboplatin in patients with resectable non-small cell lung cancer, puts the thoracic team in good position for future accrual to the phase III SWOG study (S9900). S9900 will test the paclitaxel/carboplatin preoperative adjuvant strategy against surgery alone. 3) Quality Assurance (QA)-In addition to surgical guidelines and a routine QL review process, unique aspects of NCCTG surgical QA include surgeon credentialing, video review audits, pre-enrollment surgical review, and standardized guidelines and data forms for colorectal cancer resulting from an NCI workshop organized by the NCCTG Surgical Scientific Coordinator. 4) Education-Symposia and workshops have become integral to the Surgery Committee meetings. Future efforts will focus on the training of new surgeons (residents in Cooperative Group activities. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •

The availability of an effective means of eradicating this arrhythmia in these patients at the time of surgery would permit control of rate and rhythm, limit embolic stroke, and improve cardiac performance, outcome, and the quality of life. Whereas the Maze and RIA assume randomly distributed and changing reentry which are eliminated without prior activation mapping, new data indicate that some forms of AF result from (spatially) stable reentry which can be identified by new mapping methods and focally ablated. Thus, a second project is directed toward map guided, focal cryoablation of AF. This could be performed off bypass as a more limited and rapid alternative to the more extensive and (bypass) time consuming RIA procedure. A third project is targeted at prevention and correction of postoperative atrial flutter (AFL) after the Fontan operation in congenital heart patients or after lung transplant surgery. Studies will be performed in both realistic animal models with atrial enlargement and patients with AF and AFL and will center about the use of new automated, 3-D mapping techniques and rapid numerical analysis of potentials recorded simultaneously from to 512 electrodes during the arrhythmias. Preliminary observations indicate that the proposed studies are feasible, will provide new information regarding the different mechanisms of AF and AFL that are related to atrial enlargement and/or atrial surgery, and this data will be used to develop the new surgical ablation techniques to control or prevent these arrhythmias.

Project Title: SYSTEMATIC INTEGRATION POR INTO CLINICAL PATHWAY OF HCC Principal Investigator & Institution: Schwartz, Myron E.; Surgery; Mount Sinai School of Medicine of Nyu of New York University New York, NY 10029 Timing: Fiscal Year 2002; Project Start 01-MAR-2002; Project End 31-JAN-2007 Summary: HCC Hepatocellular carcinoma (HCC) is an increasing pubic health problem in the United States. The Mount Sinai Hospital in New York has become a major referral center for this disease, with 231 new patients with HCC or suspected HCC first seen in 2000. Myron Schwartz, MD (the applicant) is Associate Professor of Surgery, Deputy Director of Liver Transplantation, and Chief of Hepatobiliary Surgery at Mount Sinai. Dr. Schwartz has proven record of patient-oriented research (POR), with 156 peerreviewed publications, and a long history of mentoring trainees who go on to successful careers in academic surgery, including 7 who are now directors of transplant programs. Dr.Schwartz's clinical and academic focus is on HCC, and he is an internationally recognized expert on HCC care. The central hypothesis of this proposal is that a program which seamlessly incorporates clinical care and POR will maximize quality of care, provide unparalleled research opportunities, and create an ideal setting for the training of clinician/researches. Dr.Schwartz's role is as director of the program, principal investigator for surgery-related projects, and mentor for trainees. The specific aims are to conduct projects exploring: 1. Etiology-" Gene Expression Profiles in HCC"; 2.Diagnosis-"Utility of AFP-L3% in Screening, Diagnosis, and Prognosis of HCC";3. Secondary prevention after resection- "Prevention of HCC Recurrence after Surgical Resection by Vaccination with Tumor-Derived Heat Shock Protein gp96 and Associated Peptides"; 4. Secondary prevention after transplantation- "Sirolimus vs Tacrolimus as the Primary Immunosuppressive Agent after Liver Transplantation for HCC"; and 5. "Treatment of unresectable HCC- "Cytokine Inhibition in HCC". Mount Sinai's

Project Title: THE ESOPHAGOGASTRIC JUNCTION IN HEALTH AND DISEASE Principal Investigator & Institution: Kahrilas, Peter J.; Professor of Medicine; Medicine; Northwestern University Office of Sponsored Programs Chicago, IL 60611 Timing: Fiscal Year 2001; Project Start 01-APR-2001; Project End 31-MAR-2006 Summary: (Verbatim from Applicant's Abstract): Gastroesophageal reflux disease (GERD) is a common disorder, affecting millions of Americans and caused by anatomical and physiological perturbations of the esophagogastric junction (EGJ). The economic impact of GERD in the US is evident by the annual expenditure of >$4 billion for pharmaceutical treatments. Although effective, medical therapy is by nature compensatory, as opposed to potentially curative surgery. However, a problem with antireflux surgery has been unpredictable postoperative dysphagia and bloating related to a diminished ability to belch. Thus, this revised RO1 application represents a collaborative effort by a gastroenterologist (Dr Kahrilas), a surgeon (Dr Joehl), and a mechanical engineer (Dr Brasseur) to study perturbations of the EGJ imposed by GERD and by surgical treatments of GERD (Nissen fundoplication). Specific aim #1 addresses antegrade EGJ function while specific aim #2 investigates mechanisms of reflux. Antegrade EGJ function will be quantified with an "esophageal stress test" using manometry with concurrent fluoroscopy while swallowing boluses of defined viscoelastic properties. These data will be complimented by a dysphagia questionnaire. Data from controls will be compared to that of GERD patients and patients after antireflux surgery. The underlying hypothesis of specific aim #1 is that a mathematical model of the EGJ, embedded within a "computer laboratory" and based on the best anatomical and physiological data obtainable will improve understanding and prevention of post-surgical dysphagia. Specific aim #2 is focused aboutextending our investigations into the interplay between anatomical and physiological factors in the pathophysiology of GERD. Investigational methodologies include using a barostat to create measured degrees of gastric distension and to ascertain EGJ compliance during fluoroscopy of the EGJ, using intragastric air insufflation to study the physiology of transient LES relaxations and high resolution manometry to map the geometry and mobility of the EGJ. An underlying hypothesis is that the optimal surgical management of a patient with tLESR induced reflux is different than of the patient with a patulous sphincter. The ultimate goal is to tailor the surgical management of GERD for the individual patient based on physiological studies of that patient with the hope that this will improve the efficacy and reduce the complications of antireflux surgery.

Project Title: THE MONOLITHIC FETAL PACEMAKER: PROTOTYPE AND DEPLOYMENT Principal Investigator & Institution: Zavitz, Daniel H.; Nanosignal, Llc. 33 N Stone Ave Tucson, AZ 85701
Studies 61
Timing: Fiscal Year 2001; Project Start 01-AUG-2001; Project End 31-JUL-2002 Summary: (Verbatim from the Applicant's Abstract): Advances in ultrasound have increased the frequency of antenatal diagnosis of complete heart block with heart failure and hydrops fetalis Because no cardiac pacemaker modality exists for intrauterine application, these patients die prenatally or postnatally. A Monolithic Fetal Pacemaker System has been designed, capable of intrauterine placement, that avoids the problems incident to an exposed lead This is applicable to fetal heart block, where pacing for 2- 4 weeks prior to Cesarean delivery should resolve hydrops fetalis permitting survival. This system can also be used prophylactically for avoiding death after fetal surgery. The pacemaker is novel because it employs an intrapleural electrode to pace heart through the pericardium, because it uses an extraordinary pathway of current passage, traversing fetal skin, and because its low profile monolithic character, permits minimally invasive implantation while avoiding cord complications. This proposed research (1) develops techniques of ultrasound-guided placement of the prototype Monolithic Fetal Pacemaker, (2) creates prototypes, and (3) in a study in pregnant sheep, leads to development of surgical techniques of deployment. If successful, this research will lead to important advances in fetal medicine and surgery, permitting survival of fetuses with complete heart block and enhancing survival of fetuses that undergo fetal surgery. PROPOSED COMMERCIAL APPLICATION: The Monolithic Fetal Pacemaker will be used by fetal interventionalists and perinatologists in fetuses with complete heart blocck. It may become a mainstay of fetal surgery, where it will be prophylactically placed at the time of fetal surgery. Broad opportunities for commercialization exit, because of the wide range of its use and the international network of clinicians in the fields of Obstetrics, Cardiac Surgery, Pediatric Cardiology, Electrophysiology and Fetal Surgery.

Project Title: TREATMENT OF DEPRESSION AFTER CORONARY BYPASS SURGERY Principal Investigator & Institution: Freedland, Kenneth E.; Professor of Medical Psychology; Psychiatry; Washington University Lindell and Skinker Blvd St. Louis, MO 63130 Timing: Fiscal Year 2001; Project Start 29-JUN-2001; Project End 31-MAY-2005 Summary: (Adapted from investigator's abstract): Depression is a common and persistent problem after coronary artery bypass graft (CABG) surgery that complicates recovery, increases the risk of cardiac events, and may exacerbate the neurocognitive deficits that are often observed in post-CABG patients. Although CABG is one of the most frequently performed operations in the United States, there have not been any randomized, controlled trials of treatments for depression in this population. The aims of this study are (1) to compare the efficacy of cognitive behavior therapy (CBT), stress management (SM), and usual care (UC) for major depression following CABG surgery; (2) to determine the effects of CBT on neurocognitive performance, psychosocial adjustment, functional status, employment status, and health-related quality of life; and (3) to collect pilot data on the relationship between the treatment of depression and the 12-month incidence of cardiac and cerebrovascular events following CABG. Consenting patients will be screened for depression 4 to 6 weeks after surgery. Those who screen positive will return for a psycho-diagnostic evaluation and additional testing approximately 1 week later. A sample of 165 patients with major depression who meet all other eligibility criteria will be randomized to 12 weeks of CBT, SM, or UC with no restriction on non-study antidepressants. Participants in all 3 arms will be monitored for
62 Surgery
worsening depression and will be referred for additional care if needed. Depression outcomes will be assessed 12 weeks post-randomization and 6 months after surgery (2 months after termination of CBT or SM.) The primary hypothesis is that the posttreatment severity of depression is lower in patients treated with CBT than with SM or UC, with baseline depression severity and non-study treatment as planned covariates. Secondary analyses will test the effects of treatment on remission, neurocognitive and functional recovery, quality of life, and examine the relationships between treatment process and outcome variables.

Project Title: TRIAL OF ANTIBIOTICS TO REDUCE RECURRENT TRICHIASIS Principal Investigator & Institution: West, Sheila K.; Professor; Ophthalmology; Johns Hopkins University 3400 N Charles St Baltimore, MD 21218 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-MAR-2005 Summary: Trachoma, caused by C. trachomatis, is the second leading cause of blindness worldwide, and control is a top priority of the blindness prevention community. In trachoma-endemic areas, 10% or more of adults have trichiasis, resulting from years of repeated infection, which is high risk for subsequent visual loss. Trichiasis can be corrected with surgery, but the recurrence rate at one year is disappointingly high, 17%, and it increases in subsequent years. There is strong evidence that ongoing exposure to infection with C. trachomatis, either from a persistent injection or exposure within families, drives ongoing scarring and trichiasis in these cases. The primary questions to be addressed by this investigation are: 1) Does post-surgical treatment of trichiasis cases with azithromycin reduce the one-year recurrence rate of trichiasis compared to standard care (topical tetracycline)? 2) Does post-surgical treatment of cases plus household members with azithromycin reduce the one-year recurrence rate of trichiasis compared to standard treatment? We propose a randomized, controlled clinical trial of 1425 adults with trichiasis scheduled for surgery in two health centers in the Lanfuro district of Ethiopia to address this questions. The three arm trial will have one arm in which cases receive a single dose of azithromycin post- surgery; a third arm in which cases will receive topical tetracycline post- surgery. Data on other risk factors will include baseline severity of trichiasis, surgery-related factors, and laboratory evidence and re- infection. Cases will be examined at 2 weeks and 2, 6, and 12 months postsurgery for recurrence of trichiasis. The results of this trial will have immediate public health impact by providing information for WHO recommendations for post-surgical treatment of trichiasis, as well as by guiding policy on azithromycin use for the 22 countries beginning National Trachoma Control programs worldwide.

Project Title: TRIAL TO REDUCE ANTIMICROBIAL PROPHYLAXIS ERRORS Principal Investigator & Institution: Kritchevsky, Stephen B.; Preventive Medicine; University of Tennessee Health Sci Ctr Health Science Center Memphis, TN 38163 Timing: Fiscal Year 2002; Project Start 16-AUG-2002; Project End 31-JUL-2006 Summary: (APPLICATION ABSTRACT): Both epidemiologic studies and randomized trials have shown that many surgical site infections (SSI) are preventable with appropriately timed antimicrobial prophylaxis. Patients receiving prophylaxis either well before or well after surgery are up to five times more likely to develop an SSI than those receiving appropriate therapy (Classen et al., 1992). Unfortunately, errors in antimicrobial prophylaxis timing are extremely common, with error rates typically
Studies 63
reported to be between 35 and 40 percent. Given that errors in antimicrobial prophylaxis are so common and the consequences of error so grave, identifying methods to assist hospitals in improving prophylaxis must be a high priority. We propose to evaluate a multifaceted, theory-based intervention to assist hospitals in progressing through stages of organizational change to improve the prophylaxis process. We will test the impact of the intervention using a rigorous group-randomized, nested, pretest-posttest design (Murray, 1998). Our specific aims over the four-year project period are: 1) Determine the incidence of medication errors related to antimicrobial prophylaxis for cardiovascular surgery, joint replacement surgery, and hysterectomy in 40 hospitals recruited to participate in the study; 2) identify organizational and system factors associated with error rates; and 3) randomize the 40 hospitals to evaluate the effectiveness of a multifaceted intervention. The intervention consists of a) the promotion of two specific process changes (the elimination of "on-call" ordering and the use of preprinted prophylaxis orders); b) a site visit; c) customized process feedback; d) facilitated benchmarking; and e) peer consultation. The 20 intervention hospitals will be compared with 20 hospitals that receive written feedback of their error rates only. The study has 80-percent power to detect a 12- to 15-percent improvement in the timing of prophylaxis in the full intervention group compared with the group that receives written feedback only. Data collection will be done at each participating hospital, and the medical records of 100 surgical patients before and after the intervention will be abstracted at each hospital to establish performance rates. Changes in the processes of care and the evolution through stages of organizational change will also be assessed. This application represents the combined efforts of three organizations devoted to improving patient care through error reduction: the Society for Healthcare Epidemiology of America, the Joint Commission on Accreditation of Healthcare Organizations, and the Centers for Disease Control and Prevention.

Each organization is providing unique abilities and expertise to address the important issue of antimicrobial prophylaxis errors. Website: http://crisp.cit.nih.gov/crisp/Crisp_Query.Generate_Screen •
Project Title: ULTRASONIC SYSTEM FOR OCULAR VISUALIZATION AND BIOMETRY Principal Investigator & Institution: Wiseman, George D.; Ultralink, Llc 2083 Hawaii Ave Ne Saint Petersburg, FL 33703 Timing: Fiscal Year 2002; Project Start 01-FEB-2002; Project End 31-JUL-2002 Summary: (Provided by Applicant): The long-term objective of this program is a commercially viable system that will play a key role in restoring and preserving vision for millions of patients in this country and abroad. The system will couple highfrequency ultrasound (40 MHz) with novel signal processing to provide accurate, precise biometry of the cornea and anterior chamber. Measurements will be used by ophthalmologists to: 1) plan refractive laser surgery of the cornea (for vision correction and restoration); 2) select the appropriate type and size of recently developed intraocular lenses (IOL) to correct refractive errors or restore vision following cataract surgery; and, 3) document causes of undesired side-effects following laser and IOL procedures, so that corrective actions can be initiated promptly. The system will incorporate advanced, patented methodology developed by the Weill Medical College of Cornell University (WMC) and Riverside Research Institute (RRI). Ultralink, Inc. has already implemented an initial "proof-of-concept" system that successfully demonstrated the practicality of these objectives. This innovative system functioned extremely well, but it also identified several practical issues that will be addressed in

this program so that these techniques can realize their full clinical and commercial potentials. The program will integrate system design (Phase I), and development and testing (Phase II) at Ultralink, WMC, and RRI.

Project Title: VENTRICULAR FUNCTION DURING CARDIAC SURGERY Principal Investigator & Institution: Spotnitz, Henry M.; Humphreys Professor of Surgery; Surgery; Columbia University Health Sciences New York, NY 10032 Timing: Fiscal Year 2001; Project Start 01-MAY-1992; Project End 31-MAY-2006 Summary: (Provided by Applicant): These studies will examine the effect of surgical correction of acquired and congenital heart disease on the systolic and diastolic properties of the left and right ventricles in human adults, children, and infants. State of the art measuring devices and algorithms will be employed for intraoperative measurements and long-term followup. Improved pump function during corrective surgery will be correlated with changes in myocardial properties, since impaired contractility and compliance can be hidden by improved hemodynamics. For specific operations in which the pathophysiology of surgical correction is not well understood, mechanisms that promote a successful long term result will be defined. Outpatient studies will examine chronic changes in ventricular size and function, which will be related to intraoperative events. Laboratory studies will develop advanced methods for intraoperative study and reduce the cost of such studies, making the technology widely available. Intraoperative measurements will include pressure by micromanometer, flow by electromagnetic or ultrasonic flowmeter, and dimensions by sonomicrometry, twodimensional echocardiography, and ventricular conductance. End-diastolic volume will be correlated with end-diastolic pressure to measure compliance, and with pressurevolume stroke work to measure contractile function (preload recruitable stroke work). Contractility will also be measured from pressure-volume loops (end-systolic pressurevolume relation). End-diastolic pressure-ventricular performance relations will also be measured, since these directly influences patient symptoms. These goals will be accomplished by a dedicated faculty with the right combination of clinical experience and laboratory background to conduct such studies effectively and safely. Results will improve care of patients undergoing cardiac surgery, will clarify deficiencies of current management, will expand understanding of the pathophysiology of heart surgery, and will make low cost methods for the study of systolic and diastolic properties generally available to cardiac surgeons and laboratory scientists.

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print.

The National Library of Medicine: PubMed One of the quickest and most comprehensive ways to find academic studies in both English and other languages is to use PubMed, maintained by the National Library of Medicine.6 The advantage of PubMed over previously mentioned sources is that it covers a greater number of domestic and foreign references. It is also free to use. If the publisher has a Web site that offers full text of its journals, PubMed will provide links to that site, as well as to sites offering other related data. User registration, a subscription fee, or some other type of fee may be required to access the full text of articles in some journals. To generate your own bibliography of studies dealing with surgery, simply go to the PubMed Web site at http://www.ncbi.nlm.nih.gov/pubmed. Type “surgery” (or synonyms) into the search box, and click “Go.” The following is the type of output you can expect from PubMed for surgery (hyperlinks lead to article summaries): •

PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND SURGERY Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and surgery.
Finding Nutrition Studies on Surgery The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only. Now that you have selected a database, click on the “Advanced” tab. An advanced search allows you to retrieve up to 100 fully explained references in a comprehensive format. Type “surgery” (or synonyms) into the search box, and click “Go.” To narrow the search, you can also select the “Title” field.

Adapted from http://ods.od.nih.gov. IBIDS is produced by the Office of Dietary Supplements (ODS) at the National Institutes of Health to assist the public, healthcare providers, educators, and researchers in locating credible, scientific information on dietary supplements. IBIDS was developed and will be maintained through an interagency partnership with the Food and Nutrition Information Center of the National Agricultural Library, U.S. Department of Agriculture.

CHAPTER 3. ALTERNATIVE MEDICINE AND SURGERY Overview In this chapter, we will begin by introducing you to official information sources on complementary and alternative medicine (CAM) relating to surgery. At the conclusion of this chapter, we will provide additional sources.
The Combined Health Information Database The Combined Health Information Database (CHID) is a bibliographic database produced by health-related agencies of the U.S. federal government (mostly from the National Institutes of Health) that can offer concise information for a targeted search. The CHID database is updated four times a year at the end of January, April, July, and October. Check the titles, summaries, and availability of CAM-related information by using the “Simple Search” option at the following Web site: http://chid.nih.gov/simple/simple.html. In the drop box at the top, select “Complementary and Alternative Medicine.” Then type “surgery” (or synonyms) in the second search box. We recommend that you select 100 “documents per page” and to check the “whole records” options. The following was extracted using this technique: •

Ayurveda: A Historical Perspective and Principles of the Traditional Health Care System in India Source: Alternative Therapies in Health and Medicine. 7(2): 36-42. March 2001.
166 Surgery
Summary: This journal article provides an overview of the history and principles of Ayurveda, the traditional medical system of India. Ayurveda, the science of life, has been the traditional system of health care in India for more than 5,000 years. This medical system was well established by 2500 to 600 BC, when it evolved into two schools, the School of Physicians and the School of Surgeons, similar to allopathy. 'Charak Samhita,' 'Susrut Samhita,' and 'Ashtang Hridaya Samhita' are the Senior Triad texts, and 'Madhav Nidan Samhita,' 'Sarangdhar Samhita,' and 'Bhavprakash Samhita' are the Junior Triad texts. Around 600 BC, Ayurveda branched into eight specialties: internal medicine; pediatrics; psychiatry; surgery; toxicology; geriatrics; eugenics and aphrodisiacs; and eye, ear, nose, and throat. According to Ayurveda, a person is composed of three body 'doshas,' three mental 'doshas,' seven 'dhatus,' and 'malas.' Harmony among the body 'doshas' of 'vata' (nervous system), 'pitta' (enzymes), and 'kapha' (mucus) and the mental 'doshas' constitutes health, and their disharmony constitutes disease. The management of illness requires balancing the 'doshas' back into a harmonious state through lifestyle interventions, spiritual nurturing, and herb-mineral formulas based on the individual's mental and bodily constitution. The article has 1 table and 14 references. (AA-M).

CHAPTER 5. CLINICAL TRIALS AND SURGERY Overview In this chapter, we will show you how to keep informed of the latest clinical trials concerning surgery.
Recent Trials on Surgery The following is a list of recent trials dedicated to surgery.8 Further information on a trial is available at the Web site indicated. •
Chemoradiotherapy Followed By Surgery and Docetaxel in Treating Patients With Pancoast Tumors Condition(s): stage II non-small cell lung cancer; stage IIIA non-small cell lung cancer; stage IIIB non-small cell lung cancer Study Status: This study is currently recruiting patients. Sponsor(s): Southwest Oncology Group; National Cancer Institute (NCI); Eastern Cooperative Oncology Group; American College of Surgeons; National Cancer Institute of Canada Purpose - Excerpt: RATIONALE: Drugs used in chemotherapy such as cisplatin, etoposide, and docetaxel use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining cisplatin and etoposide with radiation therapy may shrink the tumor so it can be removed by surgery. Giving docetaxel after surgery may kill any remaining tumor cells. PURPOSE: Phase II trial to study the effectiveness of chemoradiotherapy with cisplatin and etoposide followed by surgery and docetaxel in treating patients who have newly diagnosed Pancoast tumors, a type of non-small cell lung cancer. Phase(s): Phase II Study Type: Interventional Contact(s): see Web site below Web Site: http://clinicaltrials.gov/ct/show/NCT00062439

Image Guided System for Orthopaedic Surgery Condition(s): Orthopaedic trauma; Hip Fracture Study Status: This study is not yet open for patient recruitment. Sponsor(s): National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) Purpose - Excerpt: This project focuses on the further development and clinical testing of an image-guided surgical system. The system will help surgeons perform procedures that involve inserting a screw, guide pin, drill bit, or other straight object into bone-for example, inserting screws in a broken hip bone. These surgeries are currently done with the help of a mobile x-ray device called a C-arm, which provides the surgeon with x-ray images during the procedure. C-arms have some disadvantages, including image distortion, radiation exposure, and the need for time-consuming adjustments of the Carm during the surgery. The new method would deal with these shortcomings with a computer-based system that adds to the existing C-arm system. It would provide the surgeon with a real-time view of the insertion process, and could improve the accuracy and speed of certain surgical procedures. Disadvantages associated with C-arms include image distortion, radiation exposure, and time consuming reconfiguration of the C-arm during the insertion process. The proposed system would address these shortcomings with a computer-based system that augments the existing C-arm system.

CHAPTER 6. PATENTS ON SURGERY Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.9 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “surgery” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on surgery, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Surgery By performing a patent search focusing on surgery, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We

will tell you how to obtain this information later in the chapter. The following is an example of the type of information that you can expect to obtain from a patent search on surgery: •
Access and cannulation device and method for rapidly placing same and for rapidly closing same in minimally invasive surgery Inventor(s): Spence; Paul A. (Louisville, KY), Williamson, IV; Warren P. (Loveland, OH), Christakis; George (Toronto, CA) Assignee(s): Origin Medsystems, Inc. (Menlo Park, CA) Patent Number: 6,488,692 Date filed: March 7, 2000 Abstract: An access and cannulation device includes a mounting element such as the anastomosis mounting element disclosed in U.S. application Ser. No. 08/714,615 (now U.S. Pat. No. 5,868,763) and U.S. application Ser. No. 09/200,796. The device is used to provide access therethrough and via an incision to the interior of a hollow anatomical structure such as a vessel, an organ or the like during surgery, especially minimally invasive surgery. It includes a flexible sleeve with a suture therein for closing the sleeve and locating edges of the structure adjacent to the incision in position for proper healing after completion of a surgical procedure. A tool is also disclosed for manipulating the device to configure it for the surgery and to close it after completion of the surgery whereby the edges of the wall of the structure adjacent to an incision are approximated to promote proper healing. Excerpt(s): The present invention relates to the general art of surgery, and to the particular field of minimally invasive surgery... As discussed in the incorporated documents, there is current interest in surgical techniques that are less invasive than previous techniques. This current interest has engendered interest in many areas that were previously abandoned including coronary fastening and valve placement among other areas that will occur to those skilled in the surgical art... Furthermore, many of these procedures include use of cardiopulmonary bypass for their execution. Cardiopulmonary bypass removes the venous blood from the heart and returns it to the circulation system of the patient through the patient's aorta or through one of its branches after it has been oxygenated. This bypass procedure makes it possible to remove the heart from the circulation system in order to perform corrections on the heart and also makes it possible to arrest the heart so that there is a non-moving field that is relatively free of obstructions for the surgeon to work.

Apparatus and method for determining the relative position of bones during surgery Inventor(s): Chan; Kwan-Ho (4803 1st Pl., Lubbock, TX 79410) Assignee(s): none reported Patent Number: 6,632,226 Date filed: February 27, 2001 Abstract: A measuring gauge for measuring the relative position of two bones during surgery, the measuring gauge comprising an anchor, an adapter, an outrigger and a locking joint.
Patents 233
Excerpt(s): This invention relates to surgical apparatus and procedures in general, and more particularly to surgical apparatus and procedures for determining the relative position of bones during surgery, and still more particularly to surgical apparatus and procedures for determining the distal displacement and lateral offset of a patient's femur relative to that patient's ilium during total hip replacement surgery... Unacceptable leg length inequalities, mis-sized lateral offsets, and joint dislocations are possible adverse outcomes of total hip replacement surgeries. Leg length inequalities and mis-sized lateral offsets (including, particularly, insufficient lateral offsets) can result in a persistent limp for patients who have undergone total hip replacement surgeries. Also, joint dislocations are more likely to occur if the soft tissue tension across the replaced joint is too lax as a result of a shortened limb and/or an insufficient lateral offset... It is, therefore, generally desirable to maintain the leg length, and the amount of lateral offset, which existed prior to the total hip replacement surgery. Sometimes, however, it may he desirable during total hip replacement surgery to change the leg length, and/or the amount of lateral offset, so as to compensate for deficiencies existing in the hip joint prior to the total hip replacement surgery.

(Aichi, JP) Patent Number: 6,607,521 Date filed: August 21, 2001 Abstract: An apparatus for corneal surgery to correct a refractive error by ablating corneal tissue with a laser beam emitted from a laser source and delivered onto a cornea of a patient's eye with a light delivering optical system, the apparatus comprising an irradiation area limiting device for limiting an irradiation area of the laser beam and for varying the irradiation area, a first control device for controlling the irradiation area limiting device so as to reduce an ablation amount as the laser beam irradiates further away from a flattest meridian of astigmatism whereby effecting astigmatic correction, a second control device for controlling the irradiation area limiting device so as to increase an ablation amount as the laser beam irradiates further away from a steepest meridian of astigmatism whereby effecting astigmatic correction, and an arithmetic device for dividing a refractive power required for astigmatic correction into halves approximately-equally so that an approximately half of the astigmatic correction is achieved by the first control device and the residual astigmatic correction is achieved by the second control device. Excerpt(s): The present invention relates to an apparatus for corneal surgery to correct a refractive error by ablating corneal tissue with a laser beam, and more particularly to an apparatus suitable for astigmatic correction... An apparatus for corneal surgery to correct an refractive error of an eyeball by ablating a corneal surface with an excimer laser is conventionally known... However, astigmatic correction, especially myopic astigmatic correction, performed by using this kind of apparatus has a problem that is a hyperopic shift of spherical component often occurs after such a correction. To address this problem, two methods have been suggested: one is to minimize a size of ablation area in a meridian direction for correction so as to reduce affect of the hyperopic shift,

Apparatus for the simulation of image-guided surgery Inventor(s): Chui; Chee-Kong (Singapore, SG), Chen; Percy (Singapore, SG), Wang; Yaoping (Singapore, SG), Ang, Jr.; Marcelo H. (Singapore, SG), Cai; Yiyu (Singapore, SG), Mak; Koon-Hou (Singapore, SG) Assignee(s): Kent Ridge Digital Labs (SG), The National University of Singapore (SG), Tan Tock Seng Hospital Pte Ltd. (SG) Patent Number: 6,538,634 Date filed: December 18, 1998 Abstract: An apparatus for use in simulated image guided surgery comprises a positional transducer, clamping means located proximate to the transducer, and a processor. The transducer is responsive to a thin flexible member that can be manipulated by a user, and produces signals representative of displacement and rotation of the thin flexible member. The clamping means responds to a controlling signal to apply a predetermined variable clamping force to the flexible member. The processor receives these displacement and rotation signals, and is programmed to plot the path of the flexible member therefrom as it is manipulated by the user. Additionally, the processor produces the controlling signal to the clamping means in response to the instantaneous position along the path. The processor may be coupled to a display device for displaying an image of the instantaneous position of the flexible wire therealong, or other information. The invention also includes a related method for the simulation of image guided surgery. Embodiments of the invention can be used to simulate the manual positioning of a catheter and guidewire, as well as the haptic forces exerted by the user's hand and fingers in that positioning, or can simulate the process of balloon angioplasty, including stent deployment. Excerpt(s): The present invention relates to the field of image-guided surgery, and particularly to apparatus for the simulation of such surgery, such as may be used for pre-planning, teaching or research purposes... Minimally invasive therapeutic procedures, including surgery and interventional radiology, reduce patient discomfort, hospital stay, and medical costs. The socioeconomic impact of compensation for lost work time is also reduced. Interventional radiology began as a tool for diagnosing and treating vascular disease (defects, notably narrowing in arteries) by catheters that move along the blood vessel and guided by fluoroscopy. The interventional radiologist uses a catheter passed into a blood vessel through a puncture in the skin to gain internal access to the site of disease. The catheter is then used as a conduit to pass therapeutic devices to treat the condition. Its principle advantages include direct surgical exposure by cutting through the flesh is not needed, and many of the procedures are performed on an outpatient basis. This reduces cost and the discomfort to the patient, as well as the time of convalescence... Such procedures are typically carried out in a cardiac CathLab, where a physician wishes to assess the functions of the heart and coronary artery anatomy, or to perform procedures such as coronary angioplasty.

Applicator for laparoscopic or endoscopic surgery Inventor(s): D'Alessio; Keith R. (Cary, NC), Mainwaring; Lawrence H. (Raleigh, NC) Assignee(s): Closure Medical Corporation (Raleigh, NC) Patent Number: 6,494,896 Date filed: November 30, 1999 Abstract: A hand-held applicator delivers liquid or semi-liquid compositions, such as adhesives, to an internal tissue or organ in an even and controlled manner. The applicator includes a pump, a tubular extension that is thin enough to pass through an endoscopic pathway or trocar, a proximal end of the tubular extension being sealingly connected to the pump, and an applicator tip that attaches to the distal end of the tubular extension. The tip includes the liquid and the pump pumps the liquid to the internal tissue in an even and controlled manner without contact of the liquid by the pump. The pump is preferably a micropipetter that includes a hand-held portion having a hand-actuatable plunger that does not come in direct, physical contact with the liquid to be dispensed. The composition may be an adhesive such as an alpha-cyanoacrylate. The device may further include a wound closure device including at least two closure pins extending from the distal end of the tubular extension. The wound closure device retracts from the applicator device and orients and aligns a wound or incision target tissue site immediately prior to application of the medical composition. The device provides improved control, ergonomics, and convenience. The device is particularly useful in the field of surgery, especially in the field of laparoscopic or endoscopic surgery, where an even and controlled amount of a medically-acceptable adhesive is to be applied to a target site on an internal tissue or organ. Excerpt(s): This invention relates to the field of surgery and wound closure. More particularly, this invention relates to devices for applying medically-acceptable adhesives, such as 1,1-disubstituted ethylene monomers, to surgical sites... Medical adhesives are used as alternates and/or adjuncts to sutures and staples as wound closure devices. As used herein, "wound" encompasses all disruptions of animal tissue, regardless of manner inflicted, and includes, for example, wounds that are inflicted unintentionally, through surgery, and through natural causes (e.g., degeneration of tissue, infection, etc.) One group of medical adhesives is the monomeric forms of 1,1disubstituted ethylene monomers, such as .alpha.-cyanoacrylates. Members of this group are disclosed in, for example, U.S. Pat. Nos. 5,328,687 to Leung et al; U.S. Pat. No. 3,527,841 to Wicker et al.; U.S. Pat. No. 3,722,599 to Robertson et al.; U.S. Pat. No. 3,995,641 to Kronenthal et al.; and U.S. Pat. No. 3,940,362 to Overhults... Applying medically acceptable adhesives to surgical sites for wound closure requires that the adhesive be dispensed in a precise and controlled manner to the site. Medical practitioners have encountered problems in applying this type of adhesive to internal organs and other deep tissues due to the current limited ability to evenly and controllably dispense an appropriate and accurate amount of the desired adhesive to the site to be closed. Although devices for delivering substances to wound sites are known in the art, none of the devices provide an adequate means for delivering a predetermined amount of adhesive to the site in a controlled and even manner.

Corneal surgery apparatus Inventor(s): Sumiya; Toshifumi (Aichi, JP) Assignee(s): Nidek Co., Ltd. (Aichi, JP) Patent Number: 6,585,723 Date filed: September 2, 1999 Abstract: In a corneal surgery apparatus, a corneal shape measurement unit for measuring a three-dimensional shape of a cornea includes a measurement light projecting optical system for projecting measurement light onto the cornea and its convergent point is shifted by moving a focusing lens along an optical axis, a measurement light receiving optical system including a photo-detector for receiving reflected light from the cornea and its convergent point is shifted by moving a focusing lens along an optical axis, a scanning unit for shifting a projection spot of the measurement light on the cornea in XY directions and an arithmetic unit for performing arithmetic to obtain the three-dimensional shape of the cornea from a position of the projection spot, a result detected by the photo-detector and a position to which the focusing lens is moved. Excerpt(s): The present invention relates to a corneal surgery apparatus for ablating a part of a cornea of a patient's eye to correct a refractive error of the eye or to remove a lesion therefrom... Conventionally known is a corneal surgery apparatus that ablates a corneal stroma of a patient's eye with an excimer laser or the like to change a refractive power of the eye to correct ametropia including myopia, hypermetropia, astigmatism and the like, or to remove an affected part of the cornea such as opacity. Also known is a corneal shape measurement apparatus (hereinafter referred to as a topography apparatus) that projects a placido ring onto a cornea and photographs an image of the placido ring to measure the corneal surface shape. Further, it has also been suggested to input the corneal shape data obtained by the topography apparatus to a corneal surgery apparatus. An amount to be ablated is calculated from the data and also the postoperative refractive power to be obtained. The ablation is carried out in accordance with the calculated ablation amount... However, the above-described way presents the following problems. One of the problems lies in the case of measuring a corneal shape of a patient's eye by a topography apparatus first, and then performing surgery to correct the refractive power by a separate corneal surgery apparatus based on the data captured from the topography apparatus. In this case, the positional relationship between the topography apparatus and the patient's eye is not necessarily the same as the positional relationship between the corneal surgery apparatus and the patient's eye. It is especially
238 Surgery
so, when the measurement by the topography apparatus is carried out with the patient being sit and fixed by the face, while the surgery by the corneal surgery apparatus is carried out with the patient being laid on his back. Due to the inclination of the face, the gravity and other various factors, it is often the case that the patient's eye is not in a uniform state. This results in the possibility of ablating an unintended part of the cornea. In this case, the post-operative corneal shape may differ from the expected one and the refractive error may not be corrected as expected. Web site: http://www.delphion.com/details?pn=US06585723__ •
Coronary stabilizer for performing beating heart surgery Inventor(s): Paolitto; Anthony (St. Leonard, CA), Valentini; Valerio (Montreal, CA), Cartier; Raymond (Town of Mount Royal, CA) Assignee(s): Coroneo, Inc. (Montreal, CA) Patent Number: 6,488,618 Date filed: April 14, 2000 Abstract: The present invention provides an improved coronary stabilizer for use in cardiac surgery, and more particularly during a coronary artery bypass graft (CABG) surgery performed directly on a beating heart. The coronary stabilizer is comprised of a body contact member and a handle. An opening or arterial window is provided in the body contact member, in order to allow surgical access to a target coronary artery which is exposed through said arterial window. In a first embodiment, the body contact member is a bifurcated hand comprising first and second body contacting portions, for placement alongside a target artery. Each of said body contacting portions is contoured to provide a coronary stabilizer with a substantially saddle-shaped body contacting surface, thereby tending to promote the extrusion of immobilized myocardium tissue through the arterial window generally disposed between first and second contacting portions. The coronary stabilizer according to this first embodiment preferably has a pull-type handle and is best suited to immobilize a posterior or inferior portion of the beating heart surface, during posterior coronary artery revascularizations. In a second embodiment, a coronary stabilizer with a substantially cup-shaped body contacting surface is provided and preferably configured with a push-type handle. It is best suited to immobilize an anterior portion of the beating heart surface, during anterior coronary artery revascularizations. The coronary stabilizers according to the present invention are preferably configured with an array of surgical wire attachment fittings for engaging an elastic surgical wire, that may be looped about a target artery, in order to create a substantially bloodless surgical field during a beating heart anastomosis. The contact surfaces of the coronary stabilizers preferably have a tread or tissue-engaging texture which may be configured to provide a tractive gradient. Excerpt(s): The present invention relates to the field of surgical apparatus, and more specifically to tissue stabilizers such as may be used, for example, to perform cardiac surgery on a beating heart... The growing interest in less invasive surgery has placed emphasis on cardiac surgery as well. The main difference in heart surgery with respect to other organ surgeries, gall bladder for instance, is that the beating motion of the heart tends to complicate the delicate surgical interventions that are normally performed in cardiac surgery... Cardiac surgery has been traditionally performed with the support of a cardio-pulmonary machine, whereby the patient's blood is oxygenated outside the body through extracorporeal circulation (ECC). This allows the surgeon to perform surgical procedures on a perfectly still heart, while the patient's life support is
Patents 239
maintained by cardiopulmonary assistance. During traditional coronary artery bypass graft (CABG) surgery, the surgeon or assistant may manually or otherwise manipulate the arrested heart into a position and orientation that yields the best access to a target coronary artery requiring a bypass graft, or coronary artery revascularization.

Device for photorefractive cornea surgery in higher-order visual disorders Inventor(s): Seiler; Theo (Zell, DE), Mrochen; Michael (Dresden, DE), Kaemmerer; Maik (Dresden, DE) Assignee(s): Wavelight Laser Technologie AG (Erlangen, DE) Patent Number: 6,530,917 Date filed: September 28, 2000 Abstract: A device for photorefractive cornea surgery, in particular LASIK and PRK, of the eye for the correction of sight defects of a higher order provides for the following devices:an aberroscope (12, 14, 16, 22, 24, 28) for measuring the wave-front aberration of the entire optical system of the eye to be corrected in relation to a specific eye position,means (48) for deriving a photoablation profile from the measured wave-front aberration in such a way that a photoablation in accordance with the photoablation profile minimises the wave-front aberration, anda laser radiation source (30) and means (32, 38, 40, 48) for controlling the laser radiation in relation to the specific eye position in accordance with the photoablation profile. Excerpt(s): The invention relates to a device for photorefractive surgery on the cornea of the eye for the correction of sight defects of a higher order... Photorefractive keratectomy is a hitherto widely established procedure for correcting defective vision of a lower order, i.e. for example of myopia, hyperopia, astigmatism, myopic astigmatism and hyperopic astigmatism. The term "photorefractive keratectomy (PRK)" is usually understood to mean that an intervention on the surface of the cornea is only intended after the so-called corneal epithelium has been removed. After removal of the epithelium the Bowman's membrane or the corneal stroma is exposed and can be removed by a laser. The LASIK procedure (laser in situ keratomileusis) is generally distinguished from PRK. In the LASIK procedure an approximately 100 .mu.m to 200 .mu.m thick cornea slice (so-called "flap") with a diameter of 8 to 10 mm is cut down to a small remnant serving as a "hinge" with a so-called microkeratome. This slice (flap) is folded to the side and ablation (removal) of material is then effected by laser radiation directly in the stroma, i.e. not on the surface of the cornea. After laser treatment the lid is folded back to its original position again and healing generally takes place relatively quickly... The invention described below is suitable both for the above-described PRK as well as in particular the LASIK technique. Web site: http://www.delphion.com/details?pn=US06530917__

Devices and methods for port-access multivessel coronary artery bypass surgery Inventor(s): Boyd; Stephen W. (Redwood City, CA), Rapacki; Alan R. (San Francisco, CA), Vaska; Matthias (Palo Alto, CA), Donlon; Brian S. (Los Altos Hills, CA), Peters; William S. (Woodside, CA) Assignee(s): Hearport, Inc. (Redwood City, IA) Patent Number: 6,478,029 Date filed: August 5, 2000 Abstract: Surgical methods and instruments are disclosed for performing port-access or closed-chest coronary artery bypass (CABG) surgery in multivessel coronary artery disease. In contrast to standard open-chest CABG surgery, which requires a median sternotomy or other gross thoracotomy to expose the patient's heart, post-access CABG surgery is performed through small incisions or access ports made through the intercostal spaces between the patient's ribs, resulting in greatly reduced pain and morbidity to the patient. In situ arterial bypass grafts, such as the internal mammary arteries and/or the right gastroepiploic artery, are prepared for grafting by thoracoscopic or laparoscopic takedown techniques. Free grafts, such as a saphenous vein graft or a free arterial graft, can be used to augment the in situ arterial grafts. The graft vessels are anastomosed to the coronary arteries under direct visualization through
Patents 241
a cardioscopic microscope inserted through an intercostal access port. Retraction instruments are provided to manipulate the heart within the closed chest of the patient to expose each of the coronary arteries for visualization and anastomosis. Disclosed are a tunneler and an articulated tunneling grasper for rerouting the graft vessels, and a finger-like retractor, a suction cup retractor, a snare retractor and a loop retractor for manipulating the heart. Also disclosed is a port-access topical cooling device for improving myocardial protection during the port-access CABG procedure. An alternate surgical approach using an anterior mediastinotomy is also described. Excerpt(s): The present invention relates generally to devices and methods for performing thoracoscopic cardiac procedures. More particularly, the present invention relates to devices and methods for performing coronary artery bypass graft (CABG) surgery for multivessel coronary artery disease through port-access or closed-chest thoracoscopic methods... Coronary artery disease remains the leading cause of morbidity and mortality in Western societies. Coronary artery disease is manifested in a number of ways. For example, disease of the coronary arteries can lead to insufficient blood flow resulting in the discomfort and risks of angina and ischemia. In severe cases, acute blockage of coronary blood flow can result in myocardial infarction, leading to immediate death or damage to the myocardial tissue... A number of approaches have been developed for treating coronary artery disease. In less severe cases, it is often sufficient to treat the symptoms with pharmaceuticals and lifestyle modification to lessen the underlying causes of disease. In more severe cases, the coronary blockage(s) can often be treated endovascularly using techniques such as balloon angioplasty, atherectomy, laser ablation, stents, hot tip probes, and the like.

Distractor for use in spinal surgery Inventor(s): Michelson; Gary K. (438 Sherman Canal, Venice, CA 90291) Assignee(s): none reported Patent Number: 6,565,574 Date filed: January 23, 2001 Abstract: A distractor for use in spinal surgery for urging two adjacent vertebral bodies apart is disclosed. The distractor includes a disc penetrating portion having a hollow with an open leading end configured to facilitate insertion of the distractor into at least a portion of the disc space. The hollow is adapted to contain disc material within the extension as the distractor is being inserted at least in part between the adjacent vertebral bodies. Excerpt(s): This invention relates generally to intervertebral spinal surgery, and more particularly to surgical instrumentation and to a method for creating one or more spaces between adjacent vertebral bodies in which the space has a shape and vertebral surfaces adapted in size to receive an implant or implants to be implanted in the space, and the method of implanting those implants... The spinal disc that resides between adjacent vertebral bodies maintains the spacing between those vertebral bodies and, in a healthy spine, allows for relative motion between the vertebrae. With disease and/or degeneration a disc may become painful and/or mechanically insufficient warranting surgical fusion across the affected disc. Where fusion is intended to occur between adjacent vertebral bodies of a patient's spine, the surgeon typically prepares an opening at the site of the intended fusion by removing some or all of the disc material that exists between the adjacent vertebral bodies to be fused. Because the outermost layers of bone of the vertebral endplate are relatively inert to new bone growth, the surgeon must work on the endplate to remove at least the outermost cell layers of bone to gain access to the blood-rich, vascular bone tissue within the vertebral body. In this manner, the vertebrae are prepared in a way that encourages new bone to grow onto or through an implant that is placed between the vertebrae. An implant or insert may or may not promote fusion of the adjacent vertebral bodies, may be an artificial spinal disc, may permit surface ingrowth, and may be made of bone or inert material, such as titanium. All of these examples and more are implants... Present methods of forming this space between adjacent vertebrae generally include the use of one or more of the following: hand held biting and grasping instruments known as rongeurs; drills and drill guides; rotating burrs driven by a motor; and osteotomes, chisels, and scraping implements. Surgeons often prefer a drilling technique due to its being ease, quick, and accurate. Sometimes the vertebral endplate must be sacrificed as occurs when a drill is used to drill across the disc space and deeper into the vertebrae than the thickness of the endplate. Such a surgical procedure is typically used to prepare a space in the spine for an implant having a circular cross section and necessarily results in the loss of the hardest and strongest bone tissue of the vertebrae, the endplate, and thereby robs the vertebrae of that portion of its structure best suited to absorbing and supporting the loads placed on the spine by everyday activity. Where the surgeon chooses to forego drilling a large bore across the disc space in an attempt to preserve that good bone he must nevertheless use one of the above instruments to work upon the endplates of the adjacent vertebrae to
Patents 243
access the vascular, cancellous bone that is capable of participating in the fusion and causing active bone growth, and also to attempt to obtain an appropriately shaped surface in the vertebral bodies to receive the implant, which means and method are unreliable for that purpose.

Double endobronchial catheter for one lung isolation anesthesia and surgery Inventor(s): Amar; David (Hillcrest, NY) Assignee(s): Memorial Sloan-Kettering Cancer Center (New York, NY) Patent Number: 6,520,183 Date filed: June 11, 2001 Abstract: A double endobronchial catheter that is suited for one lung isolation anesthesia and surgery that has an outer sheath that is adapted to be introduced into the patient such that the distal end of the sheath is positioned within the patient and the proximal end remains exterior of the patient. A pair of catheters are slidingly retained in separate lumens within the outer sheath lumen. Each of the catheters has an inflatable balloon at the distal end thereof with the proximal ends extending outwardly from the proximal end of the outer sheath. A stylet is removably positioned within each of the catheters so that each catheter can be manipulated independently of the other catheter within the confines of the outer sheath so that the distal ends of the catheters can be positioned at a site within the bronchi of the patient and, upon inflation of the balloons, one of the patient's lungs can be isolated and ventilation and anesthesia administered to the other lung. Excerpt(s): The present invention relates to catheters, and more particularly, to a double endobronchial catheter that is used to isolate one lung of a patient during anesthesia and surgery... There are many operations that are carried out or performed today on a patient that require one lung of that patient to be isolated, that is, one of the patient's lungs must be kept relatively immobilized during the operation so that the surgery can be performed. Typical of such operations include thoracoscopic lung surgery, minor or major lung resection, thoracic aorta repair or reconstruction, esophageal surgery and anterior thoracic spine surgery... The need to isolate such lungs in order to operate stem from the very nature of a surgical operation performed under general anesthesia. In such operations, an anesthesia apparatus actually breathes for the patient by means of an anesthesia ventilator that acts in conjunction with an anesthesia machine. The anesthesia ventilator provides a timed, intermittent flow of gas to the patient to force that gas into the patient to expand the lungs, while the gas is expelled from the lungs as the lungs deflate. The anesthesia machine adds the anesthetic, in the form of a vapor, to the gas so that the anesthetic laden gas is provided to the patient to carry out the induction and maintenance of anesthesia in the patient during the operation. Thus under normal operation, both lungs are continually expanded and contracted during the inhalation and exhalation of the anesthetic laden gases in accordance with the normal cycling of the anesthesia ventilator.

Efficient magnet system for magnetically-assisted surgery Inventor(s): Creighton, IV; Francis M. (St. Louis, MO), Ritter; Rogers C. (Charlottesville, VA), Hall; Andrew F. (St. Charles, MO), Hastings; Roger N. (Maple Grove, MN) Assignee(s): Stereotaxis, Inc. (St. Louis, MO) Patent Number: 6,630,879 Date filed: February 3, 2000 Abstract: A system for magnetically assisted surgery includes a magnetic support structure, a patient support structure and a magnet having at least four poles attached to the magnetic support structure so that the magnet provides a near-field magnetic field in an operating region of a patient supported by the patient support structure. The magnet is moveable so that the direction of the magnetic field lines in the operating region is adjustable. The magnet may include a pair of essentially semicircular halfsegments permanently magnetized and joined in an extremely stable disk configuration. The magnetic field and gradient field provided by the magnet is such that movement of the disk in one plane combined with rotation of the disk is sufficient to orient the magnetic field during surgical use, thereby reducing interference to medical imaging devices needed during surgery. An example of a medical delivery device that may be used for surgery in conjunction with this system is a flexible endoscope or catheter having a series of magnetically permeable rings. Excerpt(s): This invention relates to systems for magnetically-assisted surgery and more particularly to systems for producing the magnetic fields required to guide surgically implanted magnetic medical devices... Several magnet systems to provide guidance for magnetic medical devices for navigation within a patient have been devised or are under development. An example of such a system is disclosed in commonly assigned application Ser. No. 09/189,633, "Articulated Magnetic Guidance System," which is hereby incorporated by reference in its entirety. A device disclosed therein includes a bed, a bed articulation system, a pair of x-ray sources, a coil or magnet articulation system, and an optional pair of additional magnets. The magnet articulation system comprises an articulation support, servo control mechanisms to provide movement of a coil or a permanent magnet along an arcuate arm both through a polar angle and in a radial direction. Optionally, the entire arm may also be pivoted through an azimuthal angle. The arm itself may comprise a track and gimbal assembly. Additional embodiments described in the referenced application include one in which the arm itself is moveable via an articulation support, another in which the magnet or coil is mounted on a pivotable ring support, and another in which the magnet or coil is mounted as an effector on a robotic arm. In the latter embodiment, it is desirable for the effector and all other parts of the robotic arm to be provided with exclusion zones to prevent accidental contact with a patient, with medical personnel, and, of course, with other items that might be damaged by such contact... Still other magnetic systems providing guidance for magnetic medical devices navigated within a patient are disclosed in commonly assigned Provisional App. Ser. No. 60/095,710, filed Dec. 14, 1998, "Method and Apparatus for Magnetically Controlling Catheters for body Lumens and Cavities," which is also incorporated by reference in its entirety. The apparatus of the invention disclosed therein generally comprises a magnet system for applying a magnetic field to a magnet-tipped distal end of a medical device. The magnetic field provides a field that can navigate, orient, and hold the distal end of the medical device in the body. The apparatus also includes a computer for controlling the magnet system. Imaging devices connected to the computer provide images of the body part through which the catheter is being navigated. Displays are provided of these images. A controller connected to the
Patents 245
computer has a joystick and a trigger to enable a user to input points on the displays for two-point and three-point navigation. The magnet system itself is preferably a set of electromagnetic coils that can be disposed around the body part to create a magnetic field of variable direction and intensity. Magnet systems suitable for such use are disclosed in U.S. Pat. Nos. 4,869,247, issued Sep. 26, 1989, "Video Tumor Fighting System," and 5,125,888, issued on Jun. 30, 1992, entitled "Magnetic Stereotactic System for Treatment Delivery," the disclosures of both of which are also incorporated by reference in their entirety.

Electrode leads for use in laparoscopic surgery Inventor(s): Greenstein; Robert J. (Tenafly, NJ) Assignee(s): Transneuronix, Inc. (Mt. Arlington, NJ) Patent Number: 6,510,332 Date filed: August 16, 2000 Abstract: This invention relates to an implant device which is designed and adapted use in laparoscopic surgery. This implant device is especially adapted for electrostimulation and/or electrical monitoring of endo-abdominal tissue or viscera. The implant device has an elongated body having on, or near, its distal end a flexible attachment member which can be folded back on to the elongated body and attached to the elongated body thereby forming a closed loop around the tissue of interest. By "looping" around or through the tissue of interest, the attachment member and the elongated body are securely attached to the tissue and will resisted displacement even in cases where the tissue is subject to vigorous, periodic peristaltic movement within the body (e.g., digestive organs). One preferred implant device of this invention has an elongated body equipped with two or more electric poles that are electrically connected to an electric connection terminal for connection to a power source, mechanism to penetrate the tissue or viscera to be treated, quick-release connecting devices to separate the penetration device from the elongated body, and a locking or attachment device which is capable of folding back and attaching to the elongated body whereby the locking device and the elongated body forms a secure and essentially continuous loop around the tissue or viscera to be treated. Excerpt(s): This invention relates to a medical implant device for electrostimulation and/or electrical monitoring of endo-abdominal tissue or viscera. More specifically, this invention provides a medical implant device having electrode leads which can be attached or affixed to the enteric or endo-abdominal tissue or viscera such that the electrode leads resist detachment in spite of the vigorous and/or periodic action or movement of the enteric or endo-abdominal tissue or viscera. The medical implant device of this invention is especially adapted for location or implantation in the endoabdominal cavity over extended periods of time... It is well known that more than 70% of illnesses affecting the digestive tract are of a functional nature. Today such illnesses are treated predominantly using pharmacological means. Since drugs generally have side effects, particularly when the drugs cure the symptom and not the underlying problem or dysfunction, they must often be administered temporally. Indeed, if the side effects are sufficiently serious, the drug may have to be discontinued before full benefit to the patient is realized; in many cases the underlying illness remains... The important role played by electrophysiology in controlling gastrointestinal activity has become increasingly apparent in recent years. Thus, the possibility exits of correcting

dysfunction by means of electrostimulation applied at specific frequencies, sites, and modalities and with regard to the self-regulating electromotor physiology of the gastrointestinal organs or tract. It has recently been shown, for example, that changes occur in the motility and electromotor conduct of the gastric tract in eating disorders (e.g., obesity, thinness, bulimia, anorexia). Disturbances in electromotor activity in diabetic gastroparesis, reflux in the upper digestive tract, and numerous other gastroenterological functional pathologies have also been observed.

Hyaluronic acid esters, threads and biomaterials containing them, and their use in surgery Inventor(s): Bellini; Davide (Montegrotto Terme, IT), Callegaro; Lanfranco (Thiene, IT) Assignee(s): Fidia Advanced Biopolymers S.r.l. (Abano Terme, IT) Patent Number: 6,632,802 Date filed: August 28, 2001 Abstract: The application discloses esters of hyaluronic acid, wherein a first part of the carboxylic functions is esterified with an araliphatic alcohol and a second part is esterified with at least one long-chain, straight aliphatic alcohol with between 10 and 22 carbon atoms. The possible remaining non-esterified carboxylic functions, if present, are salified. The application further discloses biocompatible threads having a multifilament conformation comprising filaments formed by the aforesaid esters, and their use in the fields of medicine and surgery. Excerpt(s): The present invention concerns the preparation of a new series of ester derivatives of hyaluronic acid, biocompatible threads in a multifilament conformation comprising filaments constituted by such derivatives, and their use in the fields of medicine and surgery... Suture threads are now widely used in modern surgical practice and can be made of a wide range of materials, according to the type of surgery to be performed (Abraham R. Katz et al. "A new synthetic monofilament absorbable suture made from polytrimethylene carbonate" Surgery, Gynecology & Obstetrics, September 1985, vol. 161, pages 213-222; Abraham R. Katz et al. "Evaluation of tensile and absorption properties of polyglycolic acid sutures" Surgery, Gynaecology & Obstetrics, October 1970, vol. 131, pages 701-716). It is possible, therefore, to imagine different types of suture thread with different characteristics of gauge, tensile strength, biocompatibility and biodegradability, according to whether they are intended for extensive lacerations (abdominal wall, thorax, lower limbs), or for small cuts and wounds as on the face, mouth and soft tissues. Some conditions require the material to be biocompatible but not biodegradable (as in cardiovascular surgery), while others necessitate both these characteristics (as in surgery to the urinary tract). The suture threads currently on the market vary first and foremost in the type of polymer with which they are made. Indeed, they vary from non-reabsorbable threads based on polyester, polypropylene, nylon and silk, such as Surgilene.RTM., Surgilon.RTM., Novafil.RTM. and Dermalon.RTM. by DG (Davis+Geck--American Cyanamid Company), to reabsorbable threads based on glycolic acid and collagen, such as Vicryl.RTM. and Catgut.RTM. by Ethicon (A. Pavan et al. "A Comparative Study of Poly(Glycolic acid) and Catgut as Suture Materials. Histomorphology and Mechanical Properties", Journal of Biomedical Materials Research, vol. 13, pages 477-496, 1979). As these materials all have a synthetic polymeric matrix, they are poorly biocompatible and only some of them are biodegradable, so they may cause inflammatory reactions at the lesion site where they
Patents 247
are applied (E. A. Bakkum et al. "Quantitative analysis of the inflammatory reaction surrounding sutures commonly used in operative procedures and the relation to postsurgical adhesion formation" Biomaterials 1995, vol. 16, No. 17, pages 1283-1289) and may necessitate a second surgical operation to remove them from the application site. In particular the materials used to date to stitch wounds have given rise to an inflammatory response and hyperfibrotic process, because the organism recognises that they are foreign bodies. On account of this phenomenon, hypertrophic scars and keloids are prone to form around the stitches any of the anatomical or functional characteristics of healthy tissues. Apart from being unsightly, such scars may. If they are external, cause impairment of the motor functions. For examples if they occur on the joints such as the elbow or knee. When internal organs are stitched, the hyperfibrotic process may cause the formation of adhesions with the tissues surrounding the operation site... Lastly, the use of ester derivatives of hyaluronic acid is known in the preparation of biomaterials, including suture threads, in the medical-surgical sector (European Patents EP 341745 and EP 216453).

Imaging modality for image guided surgery Inventor(s): Zylka; Waldemar (Hamburg, DE), Proksa; Roland (Hamburg, DE), Van Der Brug; Willem P. (Eindhoven, NL) Assignee(s): Koninklijke Philips Electronics N.V. (Eindhoven, NL) Patent Number: 6,490,477 Date filed: April 30, 1999 Abstract: An imaging modality, in particular a mobile CT system, comprises an imaging system for imaging an object to be examined. The imaging modality is also provided with an image guided surgery system which includes a position measuring system for measuring positions within the object and a data processor for deriving a transformation between positions within the object and the corresponding positions in the image. The position measuring device is also arranged to measure the position of the imaging system and the data processor is arranged to derive the transformation from the position and/or orientation of the imaging system. The position measuring system is notably an optical position measuring system which is arranged to measure the position of the gantry of the CT system. The data processor is arranged to derive the transformation from the measured position of the gantry. A highly accurate result is obtained when a calibration is carried out which links the position of the CT gantry to the position of the scanning plane. Excerpt(s): The invention relates to an imaging modality, including an imaging system for forming an image of an object to be examined, and an image guided surgery system, including: a position measuring system for measuring positions within the object, and a data processor for deriving a transformation between positions in the image of the object and corresponding positions within the object. The invention also relates to a method of forming an image of an object to be examined by means of an imaging system wherein a position and/or orientation in the object to be examined is measured. The invention further relates to a method of determining the position of a slice in an imaging system which forms slice images of an examination zone... Imaging systems of this kind, capable of forming a slice image of an examination zone for medical purposes, are, for example X-ray computer tomography apparatus, MR apparatus or ultrasound apparatus. Since recently systems of this kind are also used for image guided surgery in
248 Surgery
order to reproduce or track surgical instruments during an intervention in the body of a patient. The exact position of the surgical instruments can then be determined by means of a position measuring system which measures the position of markers, for example light-emitting diodes (LEDs), provided on the instruments... An imaging modality of this kind is particularly suitable for use in conjunction with image guided surgery. The image guided surgery system is used to show a position and/or orientation of a surgical instrument in an operating zone within the body of the patient to a user, such as a surgeon, during a surgical intervention. For these applications the object to be examined is a patient to be examined. The patient is examined notably so as to enable a surgical operation to be carried out as well as possible. Such a surgical operation is, for example a (radiological) intervention during which a surgical instrument is introduced into the body of the patient. The surgical instrument introduced into the body of the patient can be used to examine or treat the patient. For the introduction of the surgical instrument use is made of images made before and/or during the operation or intervention, for example X-ray images, computer tomography images or magnetic resonance images. The image guided surgery system includes the position measuring system for measuring the position and/or orientation of the surgical instrument. The image guided surgery system also includes the data processor which is provided with a computer for deriving corresponding positions in a relevant image from the measured positions of the surgical instrument. During the operation the position measuring system measures the position and/or orientation of the surgical instrument relative to the patient and the computer calculates the position and/or orientation corresponding to the measured position and/or orientation of the surgical instrument in such a previously made image. Said previously made image is displayed on a monitor, the actual position and/or orientation of the surgical instrument also being shown therein. The surgeon can observe the image on the monitor so as to see the position of the surgical instrument in the operating zone without having a direct view thereof. For example, the surgeon can observe the image on the monitor so as to determine how to move the surgical instrument in the operating zone without high risk of unnecessary damaging of tissues and notably without risk of damaging vital parts.

incorporated herein by reference... In general, these image guided systems use images of a body part or other surgical object, obtained from a scan, such as CT or MRI scan, taken before surgery to generate images on a display screen during surgery. The images of the body are correlated with a synthesized image of a surgical instrument and are used to produce, on a display screen, a real-time representation of the surgical instrument used by a surgeon with respect to the body. Prior to the scan of the body to produce body images, markers such as fiducial scanning markers are placed on the parts of the body to be scanned in order to produce fiducial image points on the scanned part of the body. The locations of the fiducial markers represented on the scanned image are correlated with the fiducial scanning markers on the body to provide a coordinate registration to be used by the computer system in determining the relative location of the various objects that the computer tracks. The surgical instrument is also registered with respect to the fiducial scanning markers, as known to those skilled in the art, by positioning the surgical instrument at each of scanning markers and recording the relative location of the instrument and markers.

Instrumented and actuated guidance fixture for sterotactic surgery Inventor(s): Franck; Joel I. (Durham, ME), Haer; Frederick C. (Brunswick, ME), Franklin; Ronald J. (Bowdoinham, ME) Assignee(s): Neutar L.L.C. (Bowdoinham, ME) Patent Number: 6,529,765 Date filed: May 24, 1999 Abstract: A method and apparatus for stereotactic surgery on a body, such as surgery on the brain or spine. A guidance fixture is used that includes a mounting base having a central axis, a controllable instrument drive for moving a surgical instrument along a constrained trajectory in response to a drive control signal, an actuated adjustment mechanism coupled between the mounting base and the controllable instrument drive, and a sensor system coupled to the adjustment mechanism. The mounting base of the guidance fixture is attached to the body and a location of the mounting base in a threedimensional image of the body is determined, for example, using a remote sensing device, such as a camera, and tracking markers, such as LEDs, attached to the guidance fixture. Sensor signals encoding the orientation of the constrained trajectory and encoding a position of the surgical instrument along the constrained trajectory are generated and transmitted from the guidance fixture. An adjustment control signal is received and the orientation of the constrained trajectory relative to the mounting base is adjusted in response to the received adjustment control signal. Excerpt(s): This invention relates to instrument guidance for stereotactic surgery... Stereotactic localization is a method for locating a target within a three-dimensional object. This method is used in the medical arts and sciences to locate a target in the human body, in particular in the brain or spine, for medical and surgical treatment. Stereotactic surgery has a history dating back to the turn of the century, when the Horsely-Clark Apparatus was described as a mechanical frame system in which an animal was immobilized. This frame system permitted reproducible targeting within the animal's brain for physiological experiments. This and similar technology found application in 1948 in the work of Wycis and Speigel. In their work, a frame was attached to a human skull. The frame permitted targeting of sites within the human brain for neurosurgical treatment. A detailed survey of the field of stereotactic surgery
Patents 251
can be found in Textbook of Stereotactic and Functional Neurosurgery, P. L. Gildenberg and R. R. Tasker (eds.), McGraw-Hill, June 1997 (ISBN: 0070236046)... One approach to stereotactic surgery involves the following steps. Fiducial scanning markers are attached to the body in one of a variety of manners, including using an attachable frame or attaching the markers to the skin with an adhesive. A scan is then taken of a body, for example of the head, to produce a three-dimensional image of the body. Scanning can be done using a variety of techniques including CT, MRI, PET, and SPECT. Images of the fiducial scanning markers that are located around the body are then located in the threedimensional image at fiducial image points. Points of interest, such as the location of a tumor, are located in the three-dimensional image with reference to these fiducial image points. The body and the image are registered by matching the locations of the scanning markers and the coordinates of the fiducial image points. In an approach to stereotactic brain surgery, a three-dimensional frame is screwed to the patient's skull prior to scanning the head. This frame serves as a mechanical reference mechanism that supports scanning fiducial markers at fiducial points around the body. The frame remains attached to the patient's skull from before scanning until after surgery is complete. Prior to surgery, a mechanical guide assembly is attached to the frame. The relative location in the image of the point of interest with respect to the fiducial image points is determined, and this relationship is used to adjust the mechanical guide assembly with respect to the fiducial points on the frame. Using the adjusted mechanical guide assembly, a surgical instrument is then guided to a location in the body that corresponds to the point of interest in the image.

Interface for laser eye surgery Inventor(s): Cowperthwaite; Michael (Mountain View, CA) Assignee(s): Visx, Incorporated (Santa Clara, CA) Patent Number: 6,558,373 Date filed: March 28, 2000 Abstract: A laser surgery system having a computer control system coupled to a laser subsystem and a patient seat. The control system is coupled to the laser through a laser alignment system. The control system can be coupled to the patient seat through a patient alignment system. The control system sends a nominal position signal to move the patient seat, laser subsystem, or both so that the patient's first eye is moved into substantial alignment with the laser beam axis. The control system can send a second nominal signal to move the patient's second eye into substantial alignment with the laser beam axis. The control system can optionally comprise both an operator display and an assistant display. The assistant display provides real-time information to an assistant positioned at an assistant station adjacent the patient seat. The control system can be programmed to display edit fields with different colors to provide an obvious indication of the refractive information of the eye. The control system can comprise an operator input for providing a pre-determined secondary ablative treatment. If it is determined that the first ablative treatment did not completely remove the epithelial layer from a target region, the operator actuates the operator input to deliver the secondary ablative treatment. Excerpt(s): The present invention relates generally to methods, systems and devices for performing corrective eye surgery. More particularly, the present invention relates to improved computer and laser system interface methods, computer interface programs,
252 Surgery
and operator system interfaces. The present invention is particularly useful for enhancing the speed, ease, safety, and efficacy of laser eye surgical procedures such as photorefractive keratectomy (PRK), laser in situ keratomileusis (LASIK), and the like... Laser eye procedures typically employ ultraviolet or infrared lasers to remove a microscopic layer of stromal tissue from the cornea to alter its refractive power. Excimer lasers (i.e. ultraviolet laser), such as the VISX STAR.TM. or STAR S2.TM. laser system, use argon and fluorine gas to create a non-thermal laser light to break molecular bonds, in a process known as photoablation. Ultraviolet laser ablation results in the photodecomposition of the corneal tissue, but generally does not cause significant thermal damage to adjacent and underlying tissues of the eye. The photoablation removes stromal tissue to change the contour of the cornea to correct myopia (nearsightedness), hyperopia (far-sightedness), and astigmatism... In general, existing laser eye surgery systems have included an operator interface for use by the laser system operator in setting-up, controlling, monitoring, and generally directing the laser treatment of the patient's eyes. The safety and efficacy of a photorefractive procedure depends in part on the operator's ability to interact with the laser control system using the operator interface. The costs of each surgical procedure are significantly affected by any unnecessary time delays in setting-up or directing the procedure. Unfortunately, existing operator interfaces are less than ideal in a number of aspects. Web site: http://www.delphion.com/details?pn=US06558373__ •
Lamp, especially a surgery lamp, with at least two bulbs Inventor(s): Maier; Stefan (Weiterstadt, DE), Wasow; Soren (Freigericht, DE) Assignee(s): Heraeus Med GmbH (Hanau, DE) Patent Number: 6,572,234 Date filed: October 3, 2000 Abstract: To achieve great security against failure in lamps for medical applications, especially lamps for surgery, two electric bulbs are placed each in a concave mirror of ellipsoidal shape as part of a reflector, the two concave mirrors having focal points which are aligned with one another along an optical axis. The concave mirror provided to serve as the main lamp is configured as a ring reflector, while the concave mirror designed to operate as a reserve lamp closes off the reflector on the side facing away from the direction of emergence of the light. Thus, in the event of a change from main lamp operation to reserve lamp operation, the illuminated field is maintained at least approximately in its size and the location does not change (X and Y directions). Excerpt(s): The invention relates to a lamp, especially a surgery lamp, with at least two electrical bulbs which can be positioned at the focal point of at least one concave mirror serving as reflector... In German Gebrauchsmuster G 93 11 156.8 there is disclosed an apparatus for the positioning on alternate sides of at least two bulbs in a predetermined position, especially in a focal point of a lamp having a concave mirror, the bulbs being disposed on an apparatus bearing a bistable mechanical position memory. The apparatus can be shifted automatically upon receiving a signal (bulb failure), whereupon a first bulb is brought away from the focal point and a second bulb is moved into the focal point, circuitry producing the movement being associated with the apparatus... Even though in this case, when a first bulb as the main bulb fails, an equally strong additional illumination without lateral shifting of the cone of light is made possible by a second bulb as a reserve bulb, the changeover requires a controlling signal which, on the basis of the shifting mechanism, does not bring about a changeover to the
Patents 253
reserve bulb without a certain delay. The result is an at least slight time-delay during some operation, which should be prevented if possible (the action of the anaesthetic decreases). In addition, there is possible wear due to natural movement, so that constant inspection of the positioning mechanism is necessary. Web site: http://www.delphion.com/details?pn=US06572234__ •
Mattress for support of a patient recovering from surgery Inventor(s): Erickson; Tomiko (10100 E. Calusa Club Dr., Miami, FL 33186) Assignee(s): none reported Patent Number: 6,516,481 Date filed: February 5, 2001 Abstract: A mattress assembly generally designed for use in hospitals and the like which is structured to effectively and comfortably support a patient during a period of recovery from a predetermined surgical procedure. The mattress assembly includes an elongated support platform having a corresponding dimension to that of a conventional hospital or like medical-type mattress and includes an opening formed therein and preferably extending therethrough. The opening is disposed in aligned, at least partially receiving relation to a predetermined portion of the patient's body directly involved in an invasive surgical procedure such as prostate surgery. More specifically, the opening is disposed, dimensioned and configured to receive and maintain portions of the patient's body, including external body parts, in an at least partially protected orientation and specifically out of supported engagement with a remainder of the support platform of the mattress. The opening may include a completely closed or at least partially open periphery, wherein the support platform may include an open area of access to facilitate positioning of medical equipment or instrumentation. The support platform preferably also includes an inclined portion disposed and configured to orient and support the head and upper torso portion of the patient's body in a partially inclined position. Excerpt(s): Virtually all health care facilities including hospitals, clinics, out-patient emergency rooms, etc. utilize substantially conventional mattresses intended for use with a hospital bed, gurney, stretcher, etc. These medical-type mattress are typically designed to include an elongated support platform of generally standard length and width, dependent upon whether the support platform is to be mounted on a hospital bed or gurney, stretcher, etc. More specifically, conventional hospital mattresses, particularly of the type designed to be mounted on an electrically powered, mechanically adjustable hospital bed have a length of substantially 80 inches and a somewhat standard width or transverse dimension of substantially 36 inches. The support platform normally includes two primary outer walls, each of which may include a supporting surface. One of the supporting surfaces is disposed in supporting relation to the frame of the hospital bed and the other is disposed in supporting relation to the patient. In addition, the interior structures of such mattresses typically include a number of coils or springs alone or in combination with a compressible, foam or other cushion like material, in order to provide a predetermined amount of support to the patient's body while at the same time allowing the mattress to be selectively disposed between a complete horizontal or flat orientation and a partially inclined orientation. The latter orientation of the support platform is typically defined by the head or proximal end of the mattress being oriented at any one of a plurality of inclined angles, which serves to orient the head, shoulders, and generally upper torso region of the
254 Surgery
patient's body in an upwardly, partially inclined position. This inclined orientation of the upper portion of the patient's body is frequently accomplished to make the patient more comfortable or to allow the patient to better view his or her surroundings and to communicate with medical personnel, visitors, etc. There are, however, a few situations wherein the patient is instructed to maintain as much as possible, the upwardly, inclined orientation described above, in order to help alleviate swelling, assist with drainage of a wound, etc... As mentioned above, the mattresses used in hospitals or like health care facilities usually comprise a standard structure which is intended to provide adequate support to the patient while resting or sleeping in a fully reclined position or in an at least partially inclined position, as set forth above. However, it is believed that medical institutions have never provided a mattress or like support platform, which is structurally adapted to more readily accommodate certain medical conditions for which the patient is being treated... More specifically, patients which have been involved in surgery or other invasive procedures frequently must remain in the hospital or like medical facility during a somewhat prolonged period of recovery. During such a recovery period the patient often experiences considerable pain or discomfort, directly associated with the surgical procedure. Such discomfort is experienced until the healing of the patient's body progresses at least to a sufficient degree to where pain is no longer an acute problem. In typical fashion, a patient recovering from surgery is placed on a conventional hospital mattress and oriented in either a fully reclined or partially reclined position, as set forth above. However, it is well known by medical personnel that forced engagement with the supporting surface of the mattress or direct contact of certain portions of the patient's body, which are directly associated with the attendant surgical procedure, frequently results in considerable pain. Because of the generally standardized design of medical type mattresses, as set forth above, the patient is forced to be oriented into a position which almost certainly results in added and oftentimes unnecessary discomfort. This is particularly true when the portion of the patient's body directly related to the surgery comes in direct supported engagement with an adjacently disposed portion of the support platform of the medical mattress on which the patient is disposed.

Method and apparatus for collecting and processing physical space data for use while performing image-guided surgery Inventor(s): Galloway, Jr.; Robert L. (Nashville, TN), Chapman; William C. (Nashville, TN), Stefansic; James D. (Nashville, TN), Herline; Alan J. (Nashville, TN), Pinson; Candice D. (Mountain View, CA) Assignee(s): Vanderbilt University (Nashville, TN) Patent Number: 6,584,339 Date filed: June 27, 2001 Abstract: A method and apparatus for collecting and processing physical space data used while performing image-guided surgery is disclosed. Physical space data is collected by probing physical surface points of surgically exposed tissue. The physical space data provides three-dimensional (3-D) coordinates for each of the physical surface points. Based on the physical space data collected, point-based registrations used to indicate surgical position in both image space and physical space are determined. The registrations are used to map into image space, image data describing the physical space of an ablative instrument used to perform the image-guided surgery, an ablation zone of
Patents 255
the instrument, the surgically exposed tissue, and a particular portion of the tissue to be resected or ablated. The image data is updated on a periodic basis. Excerpt(s): The present invention relates to using image-guided surgery techniques to collect data to insure accurate tracking of an ablation device... For over fifty years, diagnostic images have been used for surgical guidance, especially in the field of neurosurgery. Image-guided surgery implements two fundamental ideas: first, the concept of an image-space to physical-space mapping or registration, and second, the use of an extracranial device for accurate surgical guidance without direct visualization. Such ideas gave birth to stereotactic neurosurgery, a technique for locating targets of surgical interest within the brain relative to an external frame of reference. This is traditionally defined as the temporary attachment of a mechanical frame to the skull or scalp in order to define a 3-D frame space around a patient. With the advent of computed tomography (CT), the coordinates of a target (i.e. tumor) in image space could be assigned coordinates in frame space if the CT images were obtained with the attached frame. Unfortunately, frames are uncomfortable to patients, must be applied prior to imaging, and are cumbersome in the imaging environment and the operating room... These factors led to the development of frameless stereotactic surgical systems, or interactive, image-guided surgery (IIGS) systems. In traditional IIGS systems, present surgical position is tracked during an operation and displayed on pre-operatively obtained tomographic images. As the surgeon changes the current surgical position, displayed images are updated in real time. In one of the earliest IIGS systems, physical space surgical position was determined using articulated arms. The position of an articulated pointer was calculated using a personal computer (PC) and overlayed on tomographic images. Magnetic resonance images (MRI) and CT negative films were scanned into the computer and displayed as images on a video interface. Other early image-guided surgical systems also used electromechanical 3-D coordinate digitizers to indicate present surgical position on various representations of patient data, including 2-D transverse, coronal and sagittal CT or MRI slices, and on image renderings of the physical object surface. Since it was necessary to have computers capable of managing large volumes of image information (>100 Mbytes) and updating the display quickly, most early IIGS systems were developed with VME bus devices running UNIX.

Method and apparatus for improved eye-hand co-ordination during videoscopic surgery Inventor(s): Street; Graham S. B. (Impstone House, Pamber Road, Silchester, Reading, Berkshire, GB) Assignee(s): none reported Patent Number: 6,547,720 Date filed: May 5, 1999 Abstract: A stereoscopic image acquisition and display system and associated method, suitable for effective eye-hand co-ordination during videoscopic surgery, is provided. The problems of previous three-dimensional acquisition and display systems are addressed by ensuring that the convergence angle for image acquisition lies within the range of 3 to 16 degrees and that the observer's visual convergence is set within similar limits. Simultaneous display of left and right eye images avoids the problems of field sequential displays. By providing the observer with a displayed image which is sufficiently bright and ensuring that the binocular disparity between corresponding
256 Surgery
points in the left and right eye images is correct, the system allows the observer to fuse a pair of stereo-images, without causing conflict between visual accommodation and convergence. The location of the displayed image may be adjusted. Excerpt(s): This invention is concerned with the field of three-dimensional imaging and in particular with the provision of a natural three-dimensional image of an operative site via, inter alia, an endoscope, thereby improving the eye-hand co-ordination of a surgeon, whilst he/she carries out such a surgical procedure... The field of Minimally Invasive Endoscopic Surgery (MIES) has, for a period in excess of 10 years, been dependent on the use of small diameter viewing devices, collectively known as endoscopes. Some of these are flexible and a majority rigid in construction. A typical working length of the insertion portion of such an instrument would be in excess of 30 cm. The diameter of this part of the instrument will typically vary from 10 mm to as low as 1 mm or less. Small diameter optics or a coherent fibre-optic bundle transfers an image of the operative site, via the distal tip of the insertion portion located inside the patient, to an external CCD camera. The image acquired in this way is displayed on a conventional television monitor placed at a comfortable viewing distance from the surgeon... We are used to viewing live imagery on a television screen from a distance of between 6 to 12 feet. Such a screen is of considerable size and typically provides a convenient viewing window, at such a distance. Conventional television quality is sufficient to provide the definition required within this window for such passive viewing. Web site: http://www.delphion.com/details?pn=US06547720__ •
Method and system for planning corrective refractive surgery Inventor(s): Halpern; Barton L. (175 Delp Rd., Lancaster, PA 17601), Gallagher; Shawn P. (Lancaster, PA) Assignee(s): Halpern; Barton L. (Lancaster, PA) Patent Number: 6,582,078 Date filed: February 27, 2001 Abstract: The invention provides a system and method which include receiving inputs from the surgeon based upon patient data and eye measurements, calculating precise corrective settings for laser equipment utilized in the surgery, and outputting the precise corrective settings along with recommendations and cautions for the surgical procedure. It should be understood by those reasonably skilled in the art that the nomograms and formulas described in the invention are dynamic formulas subject to change over time. Changes in the nomogram are required to customize a nonogram for an individual surgeon. In addition, as the art advances, adjustments in the nomograms, including addition and removal of variables, and changes in constants will be required to keep the nomogram consistent with the rapidly evolving state of the art. These changes can be accomplished through upgrades in computer programs. However, it is this very rapidly changing art and changing industry standards, as well as the need to customize nomograms to allow for individual surgeon variability, that make this invention ideally suited for use over the internet. Excerpt(s): This invention is related to refractive eye surgery, and more particularly to a software tool for assisting surgeons in planning this surgery... Refractive errors result when the optical elements of the eye, namely the cornea and the lens, do not focus a clear image onto the retina. An eye is considered emmetropic if it has no refractive error.
Patents 257
Most eyes have at least some degree of refractive error. In myopia, the optical elements are too strong for the length of the eye, and the image is focused in front of the retina. In hyperopia, the optical elements are too weak for the length of the eye, and the image is focused behind the retina. In astigmatism, the optical elements cannot focus an image to a single point, and the image is split and focused at two separate points... When a refractive error is present, a lens may be used to refocus light onto the retina. This lens may be in the form of a spectacle lens or contact lens. Additionally, a lens surgically implanted within the eye (intrastromal or intraocular) can be used. Web site: http://www.delphion.com/details?pn=US06582078__ •
Method for minimally invasive surgery in the digestive system Inventor(s): Freeman; Lynetta J. (West Chester, OH) Assignee(s): Ethicon Endo-Surgery, Inc. (Cincinnati, OH) Patent Number: 6,543,456 Date filed: May 31, 2002 Abstract: A method for intraluminally performing a gastric bypass surgery is provided. Two anastomosis members are inserted transorally and located in a proximal position and a distal position within the digestive system. The stomach and the small intestine are transected to create a gastric pouch, a drainage loop, and a Roux limb. The distal anastomosis member joins the drainage loop to a distal portion of the intestine, and the proximal anastomosis member joins the Roux limb to the gastric pouch. Excerpt(s): The present invention relates, in general, to surgery and, more particularly, to a method of performing a surgical procedure on the digestive system... The percentage of the world population suffering from morbid obesity is steadily increasing. Severely obese persons are susceptible to increased risk of heart disease, stroke, diabetes, pulmonary disease, and accidents. Because of the effect of morbid obesity to the life of the patient, methods of treating morbid obesity are being researched... Numerous non-operative therapies for morbid obesity have been tried with virtually no permanent success. Dietary counseling, behavior modification, wiring a patient's jaws shut, and pharmacologic methods have all been tried, and, though temporarily effective, failed to correct the condition. Nonsurgical approaches using mechanical devices, such as esophago-gastric balloons to fill the stomach have also been used to treat the condition. Such devices cannot be employed over a long term, however, as they often cause severe irritation, necessitating their periodic removal and hence interruption of treatment. Thus, the medical community has evolved surgical approaches to treatment of morbid obesity. Many surgical procedures for treatment of morbid obesity may generally be classified as being directed toward creation of a smaller stomach, also known as gastro-restrictive surgery, or toward the prevention of absorption of food, the most common of which is the gastric bypass. In variations of the gastric bypass, the stomach is divided into two pouches, with the upper pouch connected to the esophagus and having a small food capacity. The lower pouch remains in situ connected to the duodenum. The upper pouch is then surgically attached to a portion of the small intestine, called the jejunum, through a small opening. The opening restricts the passage of food by the greatly reduced useable stomach. The smaller stomach causes a feeling of fullness, or early satiety, with less food consumption, causing the patient to eat less food overall. Web site: http://www.delphion.com/details?pn=US06543456__

Method for use in cataract surgery Inventor(s): Holmen; Jorgen (Kulla, Ballefors, S-549 93 Moholm, SE) Assignee(s): none reported Patent Number: 6,533,769 Date filed: May 3, 2001 Abstract: A method for treatment of residual lens epithelial cells is disclosed. The method provides increased safety during local treatment in ocular surgery by improved administration of active agents. The method is particularly useful in treatment of proliferative events in ocular surgery, such as posterior capsular opacification. Excerpt(s): The present invention relates to cataract surgery, specifically to a method for preventing proliferation of remaining lens epithelial cells after cataract surgery... The crystalline lens of the human eye is located in the posterior chamber between the posterior iris surface and the vitreous body. It is a biconvex transparent tissue without nerves and blood vessels, weighing approximately 0.2 g. The lens is enveloped in a capsule, a structureless, transparent and elastic membrane bag. Approximately 80 zonular fibres, extending between the capsule and the ciliary body, suspend the lens. The inside of the lens capsule consists of lens epithelial cells and lens fibres. The lens epithelial cells form a monolayer underlying the capsule from the anterior pole to the equator of the lens. These cells continue to undergo cell mitosis throughout life in the area located between the anterior pole and the lens equator. The lens epithelial cells that underwent cell mitosis gradually move toward the lens equator and differentiate into lens fibres. These cells make up the rest of the lens. New layers of fibre cells are constantly formed on top of those previously formed. The older fibre cells become denser and during the 3.sup.rd decade of life a hard nucleus is formed in the middle of the human lens, consisting of old dehydrated fibre cells... A cataract is defined as every form of opacity in the lens or its capsule; the lens becomes cloudy, resulting in a loss of visual ability. A cataract is a painless phenomenon, but decreases the quality of life if the lens is not surgically extracted and replaced by an artificial lens.

Method of laser cosmetic surgery Inventor(s): Keller; Gregory S. (2323 De La Vina, #104, Santa Barbara, CA 93105) Assignee(s): Keller; Gregory S. (Santa Barbara, CA) Patent Number: RE36,903 Date filed: July 26, 1999 Abstract: Laser surgery is utilized to perform cosmetic surgery. A quartz fiber is used to direct the laser energy to the target area for the incision, division or resection of tissue. An endoscope may be utilized in conjunction with the quartz fiber to perform the cosmetic surgical techniques. One application utilizes laser energy to eliminate glabellar frown lines and/or forehead wrinkles. Another application employs laser energy to rectify brow descent. A further application uses laser energy to perform a neck lift. In yet another application, laser energy is utilized to reduce nasolabial folds. The use of laser energy in cosmetic surgical procedures greatly reduces the size of the incision
Patents 259
required in the skin to perform cosmetic surgical procedures, and as a result greatly reduces the risks of potential complications. Excerpt(s): The field of the present invention is cosmetic surgery... In recent years, laser technology has been utilized in a variety of applications in industry, surveying, communications and the medical field. In the field of cosmetic surgery, however, standard procedures typically involve extensive use of scalpels for incising, dividing and resecting tissue. Depending upon the particular procedure, disadvantageous complications may result including scarring, nerve damage and reduced blood flow to the affected area which can result in skin slough... For example, to remove glabellar frown lines (between the eyebrows) and forehead wrinkles, standard cosmetic surgical technique involves an extensive procedure called a forehead lift which entails a large incision that extends from ear to ear over the top of the forehead. The forehead lift is particularly disadvantageous because it opens the patient up widely requiring the physician to stop bleeders and risk cauterizing nerves. Since this procedure creates a large thin skin flap and reduces the blood supply to the skin, there is also an increased risk of skin slough and alopecia (balding). An alternate procedure for removing glabellar frown lines and forehead wrinkles is collagen treatment. However, this treatment is temporary at best and also involves a risk of allergic reaction. Moreover, collagen has been reported to cause autoimmune disease and blindness. Web site: http://www.delphion.com/details?pn=US0RE36903__ •
Method of using matrix metalloproteinase inhibitors in filtering blebs following glaucoma filtering surgery and in the treatment of ischemic damage to the retina and optic nerve Inventor(s): Schuman; Joel S. (Wayland, MA), Fini; M. Elizabeth (Milton, MA), Chintala; Shravan K. (Quincy, MA) Assignee(s): New England Medical Center Hospitals Inc. (Boston, MA) Patent Number: 6,503,892 Date filed: April 25, 2001 Abstract: This invention provides a method of inhibiting, preventing, and/or treating conjunctival filtering bleb leaks that may occur following glaucoma filtering surgery by administering Matrix Metalloproteinase inhibitors to glaucoma patients who have undergone such surgery. The invention additionally includes a method of using Matrix Metalloproteinase inhibitors to inhibit, prevent, and/or treat ischemic damage to the retina and optic nerve in patients in need of such treatment. Excerpt(s): The invention relates to methods of using matrix metalloproteinase inhibitors in glaucoma filtering surgery and in the treatment of ischemic damage to the retina and optic nerve... The retina is comprised of a network of light sensitive nerve cells that line the back of the eye. Located at the innermost cell layer are the ganglion cells. Long filamentous extensions from the axons of these cells wind their way across the retinal surface to a central location at the back of the eye, where they turn and bunch together to form the optic nerve leading to the brain. Light-induced signals are transmitted to produce our perception of sight. The place where the axons turn is called the optic nerve head. The term glaucoma describes a group of diseases that involve optic nerve damage at the level of the optic nerve head. Glaucoma results in a progressive loss of sight and may eventually lead to blindness... Elevated intraocular pressure (IOP) is the major risk for patients who suffer from glaucoma. In a normal subject's eye, a fluid,
260 Surgery
known as the aqueous humor, circulates freely through the anterior chamber of the eye. This fluid, which is continuously produced by the eye's ciliary body, is drained from the eye, through the trabecular meshwork, back into the bloodstream. When the fluid drains properly, an appropriate fluid pressure is maintained in the anterior chamber, maintaining the shape of the cornea. Elevated IOP develops when the filtration mechanism of the trabecular meshwork is no longer adequate, leading to an increase in fluid within the anterior chamber. This increase in fluid, in turn, leads to an increase in the IOP. It is this increase in IOP that subsequently causes pressure on the optic nerve at the level of the optic nerve head. This causes damage to the optic nerve, which, in turn, may lead to blindness. Web site: http://www.delphion.com/details?pn=US06503892__ •
Methods of protecting a patient from embolization during surgery Inventor(s): Tsugita; Ross S. (Mountain View, CA), Maahs; Tracy D. (Redwood City, CA), Jang; Yue-Teh (Fremont, CA) Assignee(s): Embol-X, Inc. (Mountain View, CA) Patent Number: 6,537,297 Date filed: June 26, 2001 Abstract: A method for open surgery using a flexible elongate member having a filter on a distal region thereof. The flexible elongate member is introduced into a peripheral artery. The flexible elongate member is advanced to a site within the aorta upstream of a branch vessel from the aorta. The filter is deployed. The aorta is manipulated by diret access. The filter is removed from the aorta. Embolic material is generated and filtered before the flexible elongate member is removed from the aorta. Excerpt(s): The present invention relates generally to treating plaque deposits and occlusions within major blood vessels, more particularly to an apparatus and method for preventing detachment of mobile aortic plaque within the ascending aorta, the aortic arch, or the carotid arteries, and to an apparatus and method for providing a stent and a filter in a percutaneous catheter for treating occlusions within the carotid arteries... Several procedures are now used to open stenosed or occluded blood vessels in a patient caused by the deposit of plaque or other material on the walls of the blood vessels. Angioplasty, for example, is a widely known procedure wherein an inflatable balloon is introduced into the occluded region. The balloon is inflated, dilating the occlusion, and thereby increasing intraluminal diameter. Plaque material may be inadvertently dislodged during angioplasty, and this material is then free to travel downstream, possibly lodging within another portion of the blood vessel or possibly reaching a vital organ, causing damage to the patient... In another procedure, stenosis within arteries and other blood vessels is treated by permanently or temporarily introducing a stent into the stenosed region to open the lumen of the vessel. The stent typically comprises a substantially cylindrical tube or mesh sleeve made from such materials as stainless steel or nitinol. The design of the material permits the diameter of the stent to be radially expanded, while still providing sufficient rigidity such that the stent maintains its shape once it has been enlarged to a desired size.

Multi-function surgical instrument for facilitating ophthalmic laser surgery Inventor(s): LaHaye; Leon C. (566 Sand Pit Rd., Arnaudville, LA 70512) Assignee(s): none reported Patent Number: 6,569,153 Date filed: September 21, 2001 Abstract: A multi-function surgical instrument for facilitating ophthalmic surgery of the eye by laser means. Included are a lower ring and an upper ring. One or two intermediate rings may also be included. The lower ring includes a central aperture to capture the limbus and aid in positioning of the eye. Protuberances on the lower surface of said ring, application of vacuum between the lower surface of the ring and the eye, or both may be used to more firmly grip the eye. Ports disposed on the upper surface of the lower ring and connected to a vacuum source may be used to control hydration of the surgical field. Attached to and extending above the upper surface of the lower ring is a sterile platform for reposing temporarily removed tissues during the administration of laser pulses to other tissues. The upper ring is disposed above the surgical bed. Ports disposed along said upper ring and connected to a vacuum source may be used to control smoke and splatters resulting from the ablative procedure and create additional airflow to further control hydration of the surgical field. One, or two, intermediate rings, proximate the upper ring, may be employed to dispense irrigating liquids, gases such as air or oxygen, or both liquids and gases as may be desired onto open tissues of the eye proximate to the lower ring below. Excerpt(s): The new matter disclosed and claimed herein relates to disclosure of two additional rings, one of which may be used to dispense liquids, and the other which may be used to dispense gas, onto opened tissues of the eye during ophthalmic surgery... In the field of ophthalmic surgery the use of lasers is well known. In laser assisted in-situ kerotomileusis pulses of laser light are used to ablate desired portions of the stromal bed following temporary removal of the outer tissues of the cornea. After replacement of the temporarily removed tissues the cornea is reshaped. During such procedure, and other ophthalmic procedures involving ablation of eye tissue, positioning and fixation of the eye against movement is important, as is proper tissue hydration, control of smoke, plume and splatter, maintaining cleanliness of open tissues, etc. The invention disclosed and claimed herein relates to a multifunction instrument placed on the surface of the eye during ablative eye surgery to assist the ophthalmic surgeon to perform laser ablative eye surgery... In corneal surgery the use of lasers is well known. In such procedures precisely controlled pulses of laser light are used to remove thin layers of tissue by ablation. For instance, in photorefractive keratectomy ("PRK") the cornea is reshaped by first removing the epithelium and Bowman's layer (by various means) and ablating the stromal bed by laser (after which the epithelium and Bowman's layer are left to re-form by healing). In laser assisted in-situ kerotomileusis ("LASIK") the cornea is reshaped by temporarily removing the outer layers (epithelium, Bowman's layer and a portion of the stromal bed) thereof by sharp instrument, ablating selected areas of the underlying stromal bed by laser and then replacement of the removed tissues. Various other corneal surgery is also performed using a laser to ablatively remove selected eye tissue. Web site: http://www.delphion.com/details?pn=US06569153__

Non-invasive methods for surgery in the vasculature Inventor(s): Unger; Evan C. (Tucson, AZ) Assignee(s): ImaRx Therapeutics, Inc. (Tucson, AZ) Patent Number: 6,576,220 Date filed: May 10, 2001 Abstract: Novel methods of non-invasive intravascular surgery are disclosed, which include the intravascular administration of a composition comprising gas or gaseous precursor filled vesicles, followed by application of ultrasound in an amount sufficient to induce activation or rupture of the vesicles. The methods optionally also include the step of scanning the patient with diagnostic imaging to determine the presence of the vesicles in the region. Excerpt(s): This invention relates to the field of magnetic resonance imaging, more specifically to the use of stabilized gas filled vesicles as contrast media for magnetic resonance imaging (MRI) directed ultrasound surgery... There are a variety of imaging techniques that have been used to diagnose disease in humans. One of the first imaging techniques employed was X-rays. In X-rays, the images produced of the patients' body reflect the different densities of body structures. To improve the diagnostic utility of this imaging technique, contrast agents are employed to increase the density of tissues of interest as compared to surrounding tissues to make the tissues of interest more visible on X-ray. Barium and iodinated contrast media, for example, are used extensively for Xray gastrointestinal studies to visualize the esophagus, stomach, intestines and rectum. Likewise, these contrast agents are used for X-ray computed tomographic studies (that is, computer assisted tomography or CAT) to improve visualization of the gastrointestinal tract and to provide, for example, a contrast between the tract and the structures adjacent to it, such as the vessels or lymph nodes. Such contrast agents permit one to increase the density inside the esophagus, stomach, intestines and rectum, and allow differentiation of the gastrointestinal system from surrounding structures... Magnetic resonance imaging (MRI) is a relatively new imaging technique which, unlike X-rays, does not utilize ionizing radiation. Like computer assisted tomography (CAT), MRI can make cross-sectional images of the body, however MRI has the additional advantage of being able to make images in any scan plane (i.e., axial, coronal, sagittal or orthogonal). Unfortunately, the full utility of MRI as a diagnostic modality for the body is hampered by the need for new or better contrast agents. Without suitable agents, it is often difficult using MRI to differentiate the target tissue from adjacent tissues. If better contrast agents were available, the overall usefulness of MRI as an imaging tool would improve, and the diagnostic accuracy of this modality would be greatly enhanced.

Patents 263
includes: a laser irradiating unit having a laser beam source which emits the treatment laser beam, and an irradiating optical system which optically guides the treatment laser beam emitted from the laser beam source onto the portion; an ocular movement detecting unit which detects a potential difference between a cornea and a retina, and detects an ocular movement of the patient's eye based on the detected potential difference; and an irradiation controlling unit which controls the irradiating unit based on a result of detection by the detecting unit. Excerpt(s): The present invention relates to an ophthalmic surgery apparatus for performing treatment by irradiating a treatment laser beam to a subject's eye, and more particularly to a mechanism for aligning the irradiation optical axis of a laser irradiating optical system for applying a treatment laser beam, with a patient's eye, and also to a laser irradiation controlling mechanism associated with the alignment... As an ophthalmic surgery apparatus for performing treatment by irradiating a laser beam for treatment to a patient's eye, a corneal surgery apparatus using an excimer laser beam, for example, is known. This apparatus is used for refractive correction by changing the curvature of the cornea with an excimer laser beam irradiated to the corneal surface... In this apparatus, the patient is caused to gaze at a fixation target to fix the position of the patient's eyeball, and the irradiation optical axis of the laser irradiating optical system and the patient's eye are brought into alignment in a desired state by using an alignment target or the like. After completion of the alignment, a part of the cornea is ablated at a set amount within an intended area. Web site: http://www.delphion.com/details?pn=US06585724__ •
Ophthalmic surgery method using non-contact scanning laser Inventor(s): Lin; J. T. (Winter Springs, FL) Assignee(s): LaserSight Technologies, Inc. (Winter Park, FL) Patent Number: RE37,504 Date filed: May 27, 1998 Abstract: A refractive laser surgery process is disclosed for using compact, low-cost ophthalmic laser systems which have computer-controlled scanning with a non-contact delivery device for both photo-ablation and photo-coagulation in corneal reshaping. The basic laser systems may include flash-lamp and diode pumped UV solid state lasers (193-215 nm), compact excimer laser (193 nm), free-running Er:glass (1.54 microns), Ho:YAG (2.1 microns), Q-switched Er:YAG (2.94 microns), and tunable IR lasers, (7501100) nm and (2.5-3.2) microns. The advantages of the non-contact, scanning device used in the process over other prior art lasers include being safer, reduced cost, more compact and more precise and with greater flexibility. The theory of beam overlap and of ablation rate and coagulation patterns is also disclosed for system parameters. Lasers are selected with energy of (0.01-10) mJ, repetition rate of (1-10,000), pulse duration of 0.01 nanoseconds to a few hundreds of microseconds, and with spot size of (0.05-2) mm for use with refractive laser surgery. Excerpt(s): The present invention relates to laser ophthalmic surgery using a compact, low-cost, low-power laser system with a computer-controlled, non-contact process and corneal topography to perform corneal reshaping using either surface ablation or thermal coagulation... Various lasers have been used for ophthalmic applications including the treatments of glaucoma, cataract and refractive surgery. For non-refractive treatments (glaucoma and cataract), suitable laser wavelengths are in the ranges of
264 Surgery
visible to near infrared. They include: Nd:YAG (1064 nm), doubled-YAG (532 nm), argon (488, 514 nm), krypton (568, 647 nm), semiconductor lasers (630-690 nm and 780860 nm) and tunable dye lasers (577-630 nm). For refractive surgeries (or corneal reshaping), ultraviolet (UV) lasers (excimer at 193 nm and fifth-harmonic of Nd:YAG at 213 nm) have been used for large area surface corneal ablation in a process called photorefractive keratectomy (PRK). Corneal reshaping may also be performed by laser thermal coagulation currently conducted with Ho:YAG lasers using a fiber-coupled, contact-type process. However, the existing ophthalmic lasers as above described have one or more of the following limitations and disadvantages: high cost due to the highpower requirement in UV lasers for photorefractive keratectomy; large size and weight; high maintenance cost and gas cost (for excimer laser), and high fiber-cost for contacttype laser coagulation... In light of the above, it is an object of the present invention to provide ophthalmic laser systems which offer the advantages of: low-cost, reduced size and weight, reliability, easy-operation and reduced maintenance. Another object of this invention is to provide a computer-controlled scanning device which enables use of a low-cost, low-energy laser for photorefractive keratectomy currently performed only by high-power UV lasers.

The body unit is provided with an indented upper face defined by a longitudinally extending, centrally located channel and chamfered downwardly inclined patient positioning surfaces on opposite sides of the central channel. Converging, inclined side surfaces of the body unit are configured and strategically located to accommodate the axilla areas of a patient while the patient is
Patents 267
supported on the body unit. A removable cover that substantially conforms to the configuration of the body unit is provided in full covering relationship to the body unit. Excerpt(s): This invention relates to an improved surgical pillow especially adapted to support, cushion and position a patient while in a prone position on an operating table during rectal surgery... At the present time, positioning of a patient for rectal surgery on a conventional operating table is most usually accomplished by making up rolls of blankets, towels or other similar items which are then placed along opposite sides of the patient's torso. That technique has many disadvantages including the tendency for the rolled support to shift and tend to be displaced from the original patient supporting locations thereof, and the fact that the rolls do not provide optimum patient cushioning and positioning. Furthermore, it is difficult to arrange the blanket or towel rolls in this position such that the patient's arms can be placed comfortably hanging over the edges of the operating table. Equally as significant, although support is provided by the rolls, blanket or towels for the patient's torso, the patient is still lying flat on the table in a prone positions such that pressure is inherently applied to the central part of the patient's body. The result is a tendency for the compressive forces on the patient's torso to impede veinous blood return to the patient's heart... Efforts to solve the problem of providing comfortable and effective support and positioning of a patient in a prone position during rectal surgery have not found widespread acceptance and universal usage in part because of the complexity and cost of prior devices, the inability of the supporting devices to adequately accommodate patients of different sizes and weights, and the inordinate setup and adjustment time encountered with certain units.

The head rest is adjustably movable relative to the head frame. The head frame is adjustably movable relative to the back frame. The back frame is adjustably movable relative to the seat frame. Excerpt(s): The present invention relates to a hospital stretcher, and particularly, to a surgical stretcher used for eye surgery... Hospital stretchers having head rests that support the head of a patient during eye, head, or neck surgery are known. For example, U.S. Pat. No. 6,076,208 issued to Heimbrock et al. describes a stretcher suitable for such surgeries, which patent is hereby incorporated herein in its entirety by reference. See also U.S. Pat. No. 4,882,797 to Failor et al. Many eye surgery procedures approaching a side of the patient while seated in a surgeon's chair. In addition, it is common for a microscope or other surgical equipment to be located above the patient's eye during eye surgery. Hence, there is a limited amount of space between a surgeon's lap and a microscope or other surgical equipment used by the surgeon during eye surgery. Therefore, surgeons would appreciate a surgical stretcher having a minimum amount of
268 Surgery
structure beneath the patient's shoulder, neck, and head area thereby permitting comfortable placement of the surgeon's legs beneath the patient while, at the same time, allowing ergonomic access to the surgical equipment located above the patient. In addition, it would be desirable for any stretcher controls used to adjust the position of the patient to be readily accessible to the surgeon while the surgeon is seated alongside the patient... According to one aspect of the illustrative embodiment, the back frame defines a first, generally horizontal, upwardly facing support surface. The head frame angles upwardly to define a second, generally horizontal, upwardly facing support surface that is raised relative to the first, generally horizontal, upwardly facing support surface defined by the back frame to provide room for comfortable placement of the surgeon's legs beneath the patient.

System for performing port off-pump beating heart coronary artery bypass surgery Inventor(s): Castaneda; Javier E. (Miami, FL), Francese; Jose Luis (Miami, FL), de la Torre; Ralph (Charlestown, MA), Palmer; Matthew A. (Miami, FL) Assignee(s): Medcania, Inc. (Miami, FL) Patent Number: 6,554,823 Date filed: December 8, 2000 Abstract: A system for performing through port off-pump coronary artery bypass surgery includes a port insertable between ribs into a chest wall of a patient, a heart stabilizer extendable through and stably couplable to the port, and an instrument stabilizer adapted to dampen extraneous movement to which a surgical instrument extending through the stabilizer is subject. Excerpt(s): This invention relates broadly to surgical instruments. More particularly, this invention relates to a system of surgical instruments for performing port beating heart coronary artery bypass surgery... Substantially all coronary artery bypass (CAB) procedures are performed via an open chest method. In the procedure, the chest is opened through an incision in the middle of the chest, called a sternotomy, and the ribs are retracted and held stably open with a retractor. This provides a sufficient amount of access to the heart. The heart is then arrested and the blood flow is rerouted through a heart-lung machine. The bypass procedure is then performed, and once complete, the heart is then restarted and blood is permitted to flow through the "bypass". While this procedure is the norm, it is far from desirable. First, arresting the heart is a dangerous procedure and can lead to serious complications and even death. Second, the procedure requires a sternotomy, which is painful and traumatic. Because of this incision the recovery time is relatively long and the patient is left with a permanent large scar... More recently, some surgeons have performed coronary artery bypass surgery on a beating heart. The chest is opened via a sternotomy and retracted. Using a device called a heart stabilizer, the surgical site on the heart is essentially immobilized for suturing. The heart stabilizer is typically anchored to the retractors which are in turn anchored to the walls of the chest at the site of the incision. Direct access to the surgical site as well as immobilization of the surgical site are key to the surgery. These factors allow the surgeon to perform a suture or other operation with precision. While the methodology is effective and eliminates the potential complications of arresting the heart, the drawbacks associated with the sternotomy remain.

Transvaginal tube as an aid to laparoscopic surgery Inventor(s): McCartney; Anthony John (Swanbourne, AU) Assignee(s): Gynetech Pty Ltd. (AU) Patent Number: 6,572,631 Date filed: November 19, 1999 Abstract: A transvaginal tube adapted for insertion into the vaginal tract of a patient for use during performance of a laparoscopic hysterectomy or other laparoscopic surgery on the patient. The tube has a diameter greater than the patient's cervix opening and has a distal end and a proximal end. The proximal end is cut in a plane non-normal to its tubular axis being adapted to define the patient's cervico-vaginal junction. The tube further includes a sealing structure capable of forming a seal at the distal end of the tube during the surgery. The tube is capable of maintaining the pneumoperitoneum when inserted into the vaginal tract of the patient with the seal formed at the distal end of the tube. Excerpt(s): This invention relates to transvaginal tube which is particularly useful in laparoscopic surgery, and also to a procedure for the use of such a tube... Modern advances in laparoscopic surgical equipment have meant that surgeons are able to remove the uterus and/or ovaries laparoscopically, removing the need for a long abdominal incision... A laparoscopic radical hysterectomy for cancer has evolved from the efforts of a few oncology centres with an interest in minimising invasive surgery. The operative technique is analogous to a modification of the operation originally described by Wertheim and Meigs. The laparoscope surgeon passes a 10 mm laparoscope trans-abdominally through a sub-umbilical incision after establishing a pneumoperitineum. Using two lateral portals the ovarian pedicles are divided down to the level of the uterine arteries. The ureter is isolated and protected and the uterine vessels and parametrium are divided after mobilising the bladder. The next stage is to remove the uterus and close the vaginal vault so the pneumoperitoneum can be reestablished for the lymphadenectomy. The lymph nodes are removed by plucking them from their bed and dragging them out of the abdomen through the trans-abdominal wall port used for the grasping forceps.

deflections by adjusting the angular position of the imaging lens about complementary stage. Excerpt(s): The present invention is generally related to ophthalmic instruments and surgery. In a particular embodiment, the invention provides a mechanism and method for scanning a laser beam over a surface of a patient's eye to effect resculpting... Laserbased systems are now used in ophthalmological surgery on the surface of the cornea to correct vision defects. These systems use lasers to achieve a desired change in corneal shape, with the laser removing thin layers of corneal tissue using a technique generally described as ablative photodecomposition. These laser eye surgery techniques are useful in procedures such as photorefractive keratectomy, phototherapeutic keratectomy, laser insitu keratomileusis (LASIK), and the like... The ability to track or follow movements of a patient's tissue is recognized as a desirable feature in laser eye surgery systems. Movements of the eye include both voluntary movements and involuntary movements. In other words, even when the patient is holding "steady" fixation on a visual target, eye movement still occurs. Tracking of the eye during laser eye surgery has been proposed to avoid uncomfortable structures which attempt to achieve total immobilization of the eye. Tracking may enhance known laser eye surgery procedures, and may also facilitate new procedures, such as treatment of irregular astigmatism. Web site: http://www.delphion.com/details?pn=US06488676__

Apparatus and method for performing spinal surgery Inventor(s): Cooper, Doug Wayne ; (Redwing, MN), Buttermann, Glenn Robin ; (Mahtomedi, MN) Correspondence: FOLEY AND LARDNER; SUITE 500; 3000 K STREET NW; WASHINGTON; DC; 20007; US Patent Application Number: 20030135217 Date filed: January 14, 2002 Abstract: A cutting guide for use in spinal surgery includes a sidewall defining an internal cavity. A chisel guide, for use with the cutting guide, includes a first block member to be inserted into the internal cavity of the cutting guide to position the first block member adjacent the vertebral body. The chisel guide also includes a second block member connected to the first block member. An apparatus for creating a cavity in a vertebral body endplate and in an intervertebral disc may be a compressor or a distractor having at least one cutting implement thereon. A tensioner determines a proper elongation distance in a prosthesis implanted in a vertebral body. Excerpt(s): This invention relates to the field of spinal surgery. More specifically, this invention relates to apparatuses for creating cavities in vertebral bodies and in intervertebral discs located between the vertebral bodies. This invention also relates to methods for creating such cavities. Once the cavities are created with the apparatuses and according to the methods of the present invention, an intervertebral prosthetic device, designed to replace a damaged intervertebral disc, can be implanted in the cavities. Moreover, the implanted device may be used in vertebral body fusion or in reconstruction of mobile discs through spinal arthroplasty (i.e., disc replacement)... The human spine is a flexible structure comprised of twenty-five vertebrae. Intervertebral discs separate and cushion adjacent vertebrae. The intervertebral discs act as shock absorbers and allow bending between the vertebrae... An intervertebral disc comprises two major components: the nucleus pulposus and the annulus fibrosis. The nucleus pulposus is centrally located in the disc and occupies 25-40% of the disc's total crosssectional area. The nucleus pulposus usually contains 70-90% water by weight and mechanically may function like an incompressible hydrostatic material. The annulus fibrosis surrounds the nucleus pulposus and resists torsional and bending forces applied to the disc. Thus, the annulus fibrosis serves as the disc's main stabilizing structure. A healthy disc relies on the unique relationship of the nucleus and annulus to one another. The top and bottom surfaces of intervertebral discs abut vertebral body endplates.

The present invention will advantageously be used in laser eye surgery where accurate control of the laser beam is
Patents 273
crucial for patient safety and successful vision correction. In one embodiment, a first beam of laser energy is directed through a scanning mechanism toward an eye to ablate the eye, and a second beam of laser energy is directed through the scanning mechanism toward a sensor. When the scanning mechanism is moved by a laser eye surgery system to move the first beam across the eye, the scanning mechanism also moves the second beam across the sensor. Movement of the beam across the sensor can be used to monitor movement of the first beam across the eye. If actual movement of the first beam across the eye does not match desired movement of the beam, one or more components of the laser surgery system will shut down in order to stop the laser eye surgery procedure, thus preventing undesirable ablation of the eye. Excerpt(s): The present invention relates generally to methods, apparatus and systems for performing laser eye surgery. More particularly, the present invention relates to laser beam position monitoring methods, apparatus and systems for enhancing safety of laser eye surgery systems... Photorefractive keratectomy (PRK) and phototherapeutic keratectomy (PTK) employ laser beam delivery systems for directing laser energy to a patient's eye to selectively ablate corneal tissue to reform or sculpt the shape of the cornea and, thereby, to improve vision. Present commercial systems often employ excimer lasers. In a first type of system, positioning of the beam is generally fixed and the beam has a cross-sectional area generally corresponding to an entire surface area of a surgical site on the cornea. Cross-sectional portions of the beam are then sequentially masked or adjusted so as to selectively vary the amount of energy exposure of different portions of the surgical site so as to effect the desired sculpting. This can typically be achieved by using an iris or other exposure control mechanism. While highly effective and relatively easy to control, employing a laser beam having a cross-sectional area generally equal to the area of the treatment or surgical site (typically having a diameter of 5.0 mm to 10.0 mm) often involves the use of relatively large amounts of energy. This is typically relatively expensive, and leads to relatively large laser systems... As an alternative to such large beam diameter systems, laser "scanning" systems can be employed for corneal ablation. Such scanning systems typically employ a laser beam having a smaller cross-sectional area, thereby decreasing energy requirements. Accordingly, laser scanning systems delivering laser beams of relatively small crosssectional area can be more economic to use and normally are of smaller construction than laser systems having larger diameter beams. However, the use of such small beams complicates certain aspects of the treatment protocols required to perform the sculpting. For example, to achieve a desired level of volumetric tissue removal or ablation from the eye, the treatment beam is scanned over or otherwise moved across the eye from one position to a next during the surgical procedure. Movement of the beam is typically achieved through motorized scanning mechanisms, devices, or the like. These scanning mechanisms often regulate the position of an optical element, such as the angle of a mirrored surface, the lateral position of an offset imaging lens or the like, so as to adjust the lateral position of the beam across the treatment site. In a related type of system, the laser beam is scanned over the corneal surface while varying the cross-section of the laser beam. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Excerpt(s): The present invention relates to a biocompatible, injectable aqueous solution for use in high intensity ultrasound energy assisted surgery. More specifically the irrigation solution of the present invention contains a gas selected from the group consisting of carbon dioxide, nitrogen and mixtures thereof for the reduction and limitation of cavitation and the reduction and limitation of sonoluminescence and sonochemistry... Ultrasound energy has been extensively used in the medical field, mainly for diagnostic and therapeutic purposes it has been utilized for diagnosis in medicine mainly at a sonar pulse mode of very short duration and of high frequency and peak intensity, or at low intensities of 10.sup.-2 to 10.sup.-3 W/cm.sup.2 CW, and at a high frequency in dopier mode. Ultrasound is used in physical therapy in intensities of up to 3-5 W/Cm.sup.2 CW, for a short exposure time. Ultrasonic ablative surgery instrumentation, such as those used in phacoemulsification in ophthalmology, recanalization and thrombus dissolution in peripheral arteries, in neurosurgery, hepatic, renal, prostate and bladder resections, as well as in extracorporeal shock wave lithotripter, utilize higher power intensities that are above 10W/cm.sup.2CW. The longterm safety of diagnostic ultrasonic equipment in clinical use was questioned and evaluated with no significant effects demonstrated at intensities below 100 mW/cm.sup.2 spatial and temporal peak average intensity... High-intensity ultrasound energy (HIUE) has been used in the last three decades in a wide range of surgical procedures for the extraction of tissues such as soft tissues and other target tissues, said target tissues including kidney tissues, brain tissues, liver tissues, cataracts, etc. In the last ten years, HIUE has been utilized for aesthetic surgery in Ultrasound-Assisted Lipoplasty (UAL). In UAL, subcutaneous fatty tissue in the human body is irrigated with wetting solution, emulsified by exposure to HIUE through a probe via a stab wound in the skin, and can be evacuated simultaneously or immediately following, by the application of low-vacuum suction.

Abstract: A blade for corneal surgery for separating a corneal epithelium in a flap shape, includes: upper and lower blade surfaces; and an edge surface connecting the upper and lower blade surfaces, the edge surface having a height of 1 to 70 .mu.m and a connecting portion with each of the upper and lower blade surfaces having a curved surface. Excerpt(s): The present invention relates to a blade for corneal surgery which is suitable for separating (incising) a corneal epithelium like a flap and a corneal surgical apparatus comprising the blade... There has been known LASIK (Laser in Situ Keratomileusis) for the keratorefractive surgery in which a flap is formed by incising a corneal portion with a thickness of about 0.15 mm ranging from a corneal epithelium to a corneal stroma with a part of the cornea remaining connected like a hinge, ablating the corneal stroma in a refractive correction amount by a laser beam, and returning the flap. In the LASIK, there is used a corneal surgical apparatus called a microkeratome which serves to incise the cornea in a layered form... In recent years, attention has been paid to a method of LASEK (Laser Epithelial Keratomileusis) in which a corneal epithelium except a hinge is cut in an annular by an epi-trephine, and the corneal epithelium is immersed in alcohol and is swollen, and a flap is formed by separating the corneal epithelium from a Bowan's membrane by means of a golf knife, and a corneal stroma is ablated by a laser beam and the flap into an original position is returned. The LASEK cart also be applied to a thin cornea to which the LASIK cannot be applied. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

CURVED SURGICAL INSTRUMENTS AND METHOD OF MAPPING A CURVED PATH FOR STEREOTACTIC SURGERY Inventor(s): NOWINSKI, WIESLAW LUCJAN ; (SINGAPORE, SG), POSTON, TIMOTHY ; (SINGAPORE, SG) Correspondence: LADAS & PARRY; 26 WEST 61ST STREET; NEW YORK; NY; 10023; US Patent Application Number: 20030149351 Date filed: July 12, 1999 Abstract: The method of mapping a curved path for stereotactic surgery involves the selection of a helical-shaped path. The first step is to obtain an accurate image of the pertinent structures of the patient's internal areas. The image includes the lesion or target region and a potential opening site. Using the image, the non-target areas surrounding the lesion area are determined and evaluated for the medical acceptability of passing through them. A curved path which is substantially helical in shape is then selected within the image such that the curve avoids these non-target areas but intersects the target region and the opening site. The corresponding surgical instrument which will be used to follow the selected curved path has a rigid body having a shape which is substantially identical to the path. Excerpt(s): This invention relates to the field of stereotactic surgery, and particularly to curved instruments and method of mapping a curved path for stereotactic surgery for situations where a straight path is impossible or would be more invasive or risky than a curved path... Currently, stereotaxis is generally associated with neurosurgery, and particularly with intracranial surgery. However, in the following description, the terms "stereotaxis" or "stereotactic surgery" or "stereotactic surgical procedure" shall not be used in that limited sense; rather it should be understood that the term shall be used more generally to distinguish it from the "conventional" surgical procedures where a large incision is made in a patient. Hence, the terms "stereotaxis", "stereotactic surgery", "stereotactic surgical procedure" shall encompass those clinical procedures where a rigid instrument is inserted into a small opening and is navigated, by control of the part that remains outside, to a pre-determined area of a patient's body. However, frequent references will be made to intracranial surgery as a way of illustrating the invention and
Patents 277
its mode of operation, and therefore, such references should not be construed as a limitation on the present invention... Stereotactic surgery (also known as "stereotaxis") is well known to those skilled in the art. It is a special surgical procedure for treating an interior portion of a patient, usually the brain and other intracranial structures, by inserting a rigid probe into a small opening. In conventional open surgery, the surgeon makes an incision large enough for the surgeon to see the path leading to the area of pathology. Stereotaxis, on the other hand, does not require the surgeon to actually see the entire path, so a small opening, only big enough to insert the probe, is required. Hence, stereotactic surgical procedures offer the advantage of minimizing the damage to the tissues surrounding the lesion area, and promotes faster recovery of the patient.

Devices and methods for percutaneous surgery Inventor(s): Smith, Maurice Mell ; (Cordova, TN), Foley, Kevin Thomas ; (Germantown, TN), Clayton, John B. ; (Germantown, TN), Moctezuma, Joseph ; (Memphis, TN) Correspondence: Woodard, Emhardt, Naughton,; Moriarty and McNett LLP; Bank One Center/Tower; 111 Monument Circle, Suite 3700; Indianapolis; IN; 46204-5137; US Patent Application Number: 20030139648 Date filed: February 6, 2003 Abstract: Devices and methods for performing percutaneous spinal surgery under direct visualization and through a single cannula are shown. A device (10) is provided which includes an elongated cannula (20) having a first inner diameter (D.sub.I) and an outer diameter (D.sub.O) sized for percutaneous introduction into a patient. The cannula (20) defines a working channel (25) between its ends (21, 22) which has a second diameter (D.sub.2) equal to the diameter (D.sub.I) of the cannula sized for receiving a tool therethrough. An elongated viewing element (50) is engageable to the cannula (20) adjacent the working channel (25), preferably by a fixture (30). The fixture (30) includes a housing (31) attachable to the proximal end (22) of the cannula (20) that defines a working channel opening (35) which is in communication with the working channel (25). The housing (31) also defines an optics bore (60) adjacent the working channel opening (35). In certain embodiments, the fixture (30) supports the viewing element (50) for translation and/or rotation within the optics bore (60) along the longitudinal axis of the bore, and for rotation of the housing (31) relative to the cannula (20) so that the longitudinal axis of the optics bore (60) will rotate about the longitudinal axis of the working channel (25). Methods are also provided for performing spinal surgeries percutaneously with direct visualization and without the requirement for a fluidmaintained workspace. Excerpt(s): The present invention relates to devices, instruments and methods for performing percutaneous surgeries, particularly at locations deep within the body. One specific application of the invention concern devices, instruments and techniques for percutaneous, minimally invasive spinal surgery. In another aspect of the invention, the percutaneous surgery is performed under direct vision at any location in the body... Traditional surgical procedures for pathologies located deep within the body can cause significant trauma to the intervening tissues. These open procedures often require a long incision, extensive muscle stripping, prolonged retraction of tissues, denervation and devascularization of tissue. Most of these surgeries require a recovery room time of several hours and several weeks of post-operative recovery time due to the use of general anesthesia and the destruction of tissue during the surgical procedure. In some cases, these invasive procedures lead to permanent scarring and pain that can be more severe than the pain leading to the surgical intervention... Minimally invasive alternatives such as arthroscopic techniques reduce pain, post-operative recovery time and the destruction of healthy tissue. Orthopedic surgical patients have particularly benefitted from minimally invasive surgical techniques. The site of pathology is accessed through portals rather than through a significant incision thus preserving the integrity of the intervening tissues. These minimally invasive techniques also often require only local anesthesia. The avoidance of general anesthesia reduces postoperative recovery time and the risk of complications.

A retractor includes a working channel formed by a first portion coupled to a second portion. The first and second portions are movable relative to one another from an unexpanded configuration to an expanded configuration to increase the size of the working channel along the length of the working channel while minimizing trauma to skin and tissue. Excerpt(s): The present invention relates to devices, instruments and methods for performing percutaneous surgeries... Traditional surgical procedures for pathologies located deep within the body can cause significant trauma to the intervening tissues. These open procedures often require a long incision, extensive muscle stripping, prolonged retraction of tissues, denervation and devascularization of tissue. These surgeries can require operating room time of several hours and several weeks of postoperative recovery time due to the use of general anesthesia and the destruction of tissue during the surgical procedure. In some cases, these invasive procedures lead to permanent scarring and pain that can be more severe than the pain leading to the surgical intervention... The development of percutaneous procedures has yielded a major improvement in reducing recovery time and post-operative pain because minimal muscle and tissue dissection is required and the procedures can be performed under local anesthesia. For example, minimally invasive surgical techniques are desirable for spinal and neurosurgical applications because of the need for access to locations deep within the body and the danger of damage to vital intervening tissues. While developments in minimally invasive surgery are steps in the right direction, there remains a need for further development in minimally invasive surgical devices and techniques.

The chamber is held in place by a suction ring or the like and contains a window that is transparent to necessary ultraviolet radiation, visible light and infrared radiation wavelengths. The chamber is connected to a control system that controls the temperature and humidity within the chamber and provides for the evacuation of ablation by-products from the surgical site. Excerpt(s): This invention relates generally to the field of laser refractive surgery and, more particularly, to a device for controlling the environment at the surgical site during laser refractive surgery... The human eye in its simplest terms functions to provide vision by transmitting light through a clear outer portion called the cornea, and focusing the image by way of a crystalline lens onto a retina. The quality of the focused image depends on many factors including the size and shape of the eye, and the transparency of the cornea and the lens... The optical power of the eye is determined by the optical power of the cornea and the crystalline lens. In the normal, healthy eye, sharp images are formed on the retina (emmetropia). In many eyes, images are either formed in front of the retina because the eye is abnormally long (axial myopia), or formed in back of the retina because the eye is abnormally short (axial hyperopia). The cornea also may be asymmetric or toric, resulting in an uncompensated cylindrical refractive error referred to as corneal astigmatism. In addition, due to age-related reduction in lens accommodation, the eye may become presbyopic resulting in the need for a bifocal or multifocal correction device.

Fluoroscopic image guided orthopaedic surgery system with intraoperative registration Inventor(s): Barrick, Earl Frederick ; (McLean, VA) Correspondence: HARNESS, DICKEY & PIERCE, P.L.C.; P.O. BOX 828; BLOOMFIELD HILLS; MI; 48303; US Patent Application Number: 20030060703 Date filed: August 29, 2002
284 Surgery
Abstract: A fluoroscopic image guided surgery system, comprising a C-arm fluoroscope for obtaining fluoroscopic images of an object bone, the C-arm fluoroscope including at least one set of emitters; a reference bar capable of attaching to an object bone, the reference bar including emitters; a surgical instrument for performing an operation, the instrument including emitters; a digitizer system in communication with the at least one set of emitters of the C-arm fluoroscope, the emitters of the reference bar, and the emitters of the surgical instrument so that the digitizer system can determine a position of each of the C-arm fluoroscope, the reference bar, and the surgical instrument; and a single fiducial marker for attachment to an object bone, the single fiducial marker being visible in the fluoroscopic images for determining a position of an object bone relative to the digitizer system. Excerpt(s): In orthopaedic surgery it is often necessary to insert a guide pin for a cannulated screw, drill bit, or other screw (hereafter referred to as a fixation device) into a bone at a predetermined trajectory. Pre-operative planning depends on twodimensional radiographic images which typically consist of two views taken at approximately right angles to one another. From these two views it is possible to determine the shape and structure of a long bone. Using that method, the path of insertion for a guide pin for a cannulated screw, drill bit, or screw is accurately determined. However, in practice the actual aiming of a fixation device is an inaccurate art, as the object bone is often seen only at one surface or is not seen at all and, therefore, positioning is dependent on fluoroscopic visualization. This method is also time consuming as the C-arm images must be taken separately and the drapes must be rearranged each time an image is taken. As bony tissue is unyielding, the track of the pin or drill bit is determined by the angular approach before entering the object bone. This angular approach is difficult to determine under normal circumstances and often multiple attempts are needed, as feedback is obtained from repeated fluoroscopic images. Existing methods of calculating the proper angle of guide pin for a cannulated hip screw insertion for hip pinning involve placing data manually into a computer program, which in turn outputs an angle of guide pin for a cannulated hip screw insertion... Radiation exposure is a necessary part of any procedure for calculating the proper angle of a guide pin, drill bit, or screw insertion. Radiation exposure is considered to be a hazard. Ionizing radiation has no safe threshold of exposure below which it ceases to have adverse effects, although an arbitrary level is assumed. There has been a recent upward revision of risk estimates of radiation exposure, but absolute levels of safe exposure remain unknown. Exposure to the surgical team as well as the patient during orthopaedic procedures using fluoroscopy is a universal concern. Consequently, a reduction in the amount of radiation exposure is highly desirable... Operative stereotactic localization using either frames or three-dimensional digitizers is currently being used in neurosurgery or otoloaryngology. Those methods require the use of computed axial tomography (CT) or magnetic resonance imaging (MRI) prior to surgery. They also involve placing markers on the scalp prior to the imaging study of the head. The markers must be left in the same position until surgery is performed in order to confirm intraoperative registration. Such imaging studies are routinely performed for most intracranial procedures but are impractical for most orthopaedic procedures, especially those involving long bones. A probe marked with light emitting diodes (LEDs) or other digitizing emitters is used to localize these markers or pins using a three-dimensional digitizing device at the time of surgery. A disadvantage of this system is that the images are normally obtained hours before use; thus, the images used are not up to date (real time) and are often not reflective of the current condition of the object bone.

Hand, wrist and forearm device for patients during surgery Inventor(s): Atwater, Kim A. ; (Washington, DC), Bryant, Marian J. ; (Silver Spring, MD) Correspondence: KILE GOEKJIAN LERNER & REED PLLC; THE EVENING STAR BUILDING; 1101 PENNSYLVANIA AVE, N.W.; SUITE 800; WASHINGTON; DC; 20004; US Patent Application Number: 20030056793 Date filed: September 23, 2002 Abstract: A hand, wrist and forearm device for patients during surgery, comprising a pair of mating shells which fit about the patient's hand, and wrist and forearm. Each shell has a generally accurate lateral section wrist and forearm channel and a larger, generally accurate longitudinal section hand enclosure. The two shells are loosely hinged together along one edge, with a mutually mating closure provided along the edge generally opposite the hinges. The interior is preferably lined with removable padding, such as gel packs, visco-elastic material in order to apply light pressure to the hand and stabilize the position of surgical device on the hand. The pressure of the removable padding also provides a light outward pressure to stabilize the two halves of the assembly during use. Excerpt(s): Surgical procedures have evolved into a broad range of different types of operations, with patient positioning depending upon the specific procedure to be accomplished. While most general surgery is performed on a supine patient under the influence of a general anesthetic, other types of surgery require the patient to be positioned in other than a supine position, with hands and arms extended beside or tucked along the side of the patient. An example is the lithotomy position, wherein a patient is generally positioned in a modified supine position with the hips and knees flexed and the legs supported by canvas straps or stirrups, the arms and hands being placed beside the patient, often on arm boards, or loosely cradled over the lower abdomen and secured by the lower end of a blanket. Occasionally the patient may incur injury to the hands through improper positioning of the arms and hands, through pressure when a surgeon leans over and inadvertently bears against the hand, or through crush injuries when the leg portion of the surgical table is raised after the surgery is completed. During surgery a patient is unusually very vulnerable, as the patient is under anesthesia and normal pain warning reactions are blocked... The bones and other structure of the hands are some of the more fragile components of the human body, and oftentimes inadvertent pressure upon one or both hands, can lead to damage to the hands in the form of a broken bone or pulled tendon, soft tissue, or nerve damage, in addition to transient ischemic problems due to loss of circulation. Such problems are, of course, extremely difficult for a patient, who is often bedridden after surgery and who may have no significant ability to perform any physical act other than with his or her hands and arms. Injury to a patient's hands may deprive the patient of the only other physical activity available until the primary surgical healing process is well underway. Of course, such extra incapacity is a distraction to a positive emotional attitude of the patient during recovery. The cost of inadvertent hand and arm injuries to patients during surgery can be considerable, as the medical profession has a duty of great care during such operations, when the unconscious patient is totally at the mercy of the medical staff performing the procedure... Accordingly, a need exists for a device which may be applied to the hand(s), wrist(s) and lower arm(s) of a patient who is to experience general anesthesia in order to isolate the extremities of the patient from

Implant system for glaucoma surgery Inventor(s): Patel, Anilbhai S. ; (Arlington, TX) Correspondence: ALCON RESEARCH, LTD.; R&D COUNSEL, Q-148; 6201 SOUTH FREEWAY; FORT WORTH; TX; 76134-2099; US Patent Application Number: 20030153863 Date filed: February 13, 2002 Abstract: An implant system which facilitates and improves the non-penetrating deep sclerectomy/canalostomy surgery by assured maintenance of the scleral aqueous filled space by a basic permanent chamber which can be easily connected into the opening of the Schlemm's canal by adjustable connecting tubes. This implant system also provides surgical options for penetrating through Descemet's membrane as well as for outflow into the subconjunctival space though the superficial scleral layer. Excerpt(s): This invention relates generally to the field of glaucoma surgery and, more particularly, to an implant for glaucoma surgery... Glaucoma is a disease of the eye that causes blindness in millions of people. The disease is not understood totally, and many do not even categorize glaucoma as a single disease. Glaucoma is more accurately identified as an optic neuropathy characterized by a specific pattern of optic nerve head and visual field damage, which are the end result of a number of different conditions that can affect the eye. Elevated intraocular pressure (IOP) is an important risk factor for the development or progression of glaucomatous damage. Elevated IOP can be caused either by elevated production of aqueous humor in the eye or by restricted flow of the aqueous from the eye. There are several pharmaceutical treatments for glaucoma, including beta-blockers and prostaglandin analogs but in extreme cases, surgical intervention to increase aqueous outflow is used... There are several and confusing terms used for the glaucoma surgery involving deep sclerectomy. They include viscocanalostomy, non-penetrating deep sclerectomy, and penetrating conversions of these operations. Deep sclerectomy is the term commonly used for the non-penetrating glaucoma surgery in which deep layers of sclera are removed after the deep scleral delamination down to the Descemet's membrane without penetrating into the anterior chamber. This delamination is carried out carefully up to and including the transition zone into the anterior trabecula up to about 1 mm in front of Schwalbe's line, resulting in a window for the controlled outflow of the aqueous humor through the trabeculaDescemet's membrane and the controlled reduction in the IOP, thus avoiding postsurgical hypotony. Schlemm's canal is also excised for the width of the removed deep sclera. Also removed if necessary is the juxta-canalicular trabecular meshwork tissue with a fine forceps, leaving behind the innermost bulk of the trabecular meshwork. This is done to assure sufficient percolation of the aqueous humor. This additional step has also been called "ab externo trabeculectomy" and is also considered non-penetrating because no direct entry in the anterior chamber is done as is the case with trabeculectomy which removes the entire trabecular meshwork.

A swivel member is attached to the patient's head by a cranial structure. A port in the swivel member is oriented to the reference planes by inserting a coupling member into the horizontal slot of the teeth indexing member and into the port of the swivel member, aligning the coupling member to the scribe lines on the teeth indexing member, and securing the oriented swivel member in place. The port thereby records the reference planes. With the teeth indexing member removed and the coupling member reinserted into the oriented port of the swivel member, the coupling member can measure an original position of the teeth and jaws and indicate desired changes to the original position of the teeth and jaws relative to the reference planes in x-, y-, and z-dimensions. An indicator member when independently inserted into the slot of the teeth indexing member assists in designing osteotomies relative to the reference planes. Excerpt(s): The applicant's invention is a method and apparatus for use in orthognathic surgery. This type of surgery involves the correction of dentofacial deformities and is also referred to as maxillofacial surgery, reconstructive jaw surgery or surgical orthodontics... During orthognathic surgery teeth and jaws of a patient are repositioned. Prior to surgery, desired changes to an original position of the patient's teeth and jaws can be determined by clinical evaluation of the patient's head, evaluation of the patient's head X-ray, and evaluation of articulator mounted dental models. The desired changes to the teeth and jaws can be measured in three dimensions, parallel and perpendicular to reference planes. Three reference planes that can be used are a horizontal plane, a sagittal plane and a frontal plane. The horizontal plane is defined by three points on the patient's head. The sagittal and frontal planes are perpendicular to each other as well as to the horizontal plane. The reference planes are common to the patient's head, head Xray and articulator mounted dental models. The desired changes to the teeth and jaws
Patents 291
can be described in terms of x-, y-, and z-dimensions. The surgeon attempts to make actual changes to the original position of the teeth and jaws that are identical to the desired changes... Prior art has been published by G. Wylie, B. Epker and J. Mosop in the International Journal of Adult Orthodontics and Orthognathic Surgery, 1988; 3:143-147. A technique is described to assist in designing osteotomies using a maxillary measuring appliance. The device consists of a horizontal table indexed to the teeth and having an adjustable calibrated vertical pillar that can slide along the length of the horizontal table. This technique is deficient in that orientation of the horizontal table is limited to a row of teeth as a reference line. Also, it is limited to one side of a dental arch at a time. Measuring as well as marking osteotomy lines is inaccurate due to parallax problems. Osteotomies cannot be designed in a continuous manner on both sides of a jaw. In addition, the device is limited to designing osteotomies and cannot measure and record an original position of or actual changes to teeth and jaws relative to reference planes.

Method for treating nerve injury caused as a result of surgery Inventor(s): Steiner, Joseph P. ; (Mount Airy, MD), Burnett, Arthur L. ; (Baltimore, MD), Snyder, Solomon ; (Baltimore, MD) Correspondence: GUILFORD PHARMACEUTICALS C/O; FOLEY & LARDNER; 3000 K STREET, NW; WASHINGTON; DC; 20007-5143; US Patent Application Number: 20030203890 Date filed: May 29, 2002 Abstract: The present invention relates generally to methods for treating or preventing nerve injury in a warm-blooded animal caused as a consequence of surgery by administering neurotrophic compounds described below. The invention relates more specifically to methods for treating or preventing nerve injury caused as a consequence of prostate surgery as well as erectile dysfunction. Excerpt(s): The invention relates generally to methods for treating nerve injury caused as a consequence of surgery. The present invention relates more specifically to methods for treating nerve injury caused as a consequence of prostate surgery, or for methods of neuroprotection of penile innervation, by administering a neurotrophic compound to a patient in need thereof... The peptidyl-prolyl isomerases ("PPIases") are a family of ubiquitous enzymes which catalyze the interconversion of cis and trans amide bond rotamers adjacent to proline residues in peptide substrates. See, for example, Galat, A., Eur. J. Biochem. (1993) 216:689-707 and Kay, J. E., Biochem. J. (1996) 314:361-385. The PPIases have been referred to as "immunophilins" because of their interaction with certain immunosuppressant drugs. Schreiber, S. L., Science (1991) 251:283-287; Rosen, M. K. and Schreiber, S. L., Angew. Chem. Intl. Ed. Engi. (1992) 31:384-400... The PPIase, cyclophilin A, was found to be the intracellular protein target for the potent immunosuppressant drug cyclosporin A. Subsequently, the structurally unrelated macrolide immunosuppressant FK506 was discovered to bind to a different PPIase enzyme which was named FK506-binding protein, or FKBP. Rapamycin, another macrolide drug which is a structural analogue of FK506, also interacts with FKBP. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Method of interventional surgery Inventor(s): Seward, Kirk Patrick ; (Dublin, CA), Pisano, Albert P. ; (Danville, CA) Correspondence: FISH & RICHARDSON P.C.; 500 ARGUELLO STREET, SUITE 500; REDWOOD CITY; CA; 94063; US Patent Application Number: 20030055400 Date filed: September 20, 2001 Abstract: A method of interventional surgery is described. The method may include inserting an actuator within a body of a vascularized organism and positioning the actuator adjacent a target region within a vessel of the body. The actuator is operated to cause a needle thereof to move in a substantially perpendicular direction relative to a wall of the vessel to produce an opening therein. A therapeutic or diagnostic agent may be delivered by the needle to the target region via the opening in the vessel wall. Excerpt(s): The present relates generally to surgical devices, and more particularly to microfabricated surgical devices for use in catheter-based interventional procedures... Biological and surgical microelectromechanical systems (MEMS), useful for their ability to be placed into and easily maneuvered within a patient's body, are touted as the fastest growing area of micro-systems. For example, microcatheters are used in many medical applications for minimally invasive surgery. There are presently over one million surgical uses of catheters per year in the United States, representing a huge market... As surgeons continue to adopt and perform advanced surgical procedures, the miniaturization of medical devices is taking place, allowing surgery with small external incisions and catheter-based microsurgical tools. With roots in laparoscopic surgery (entering the abdomen through the navel and small holes in the midsection), minimally invasive surgery can be performed by inserting catheters in the femoral artery at the base of a patient's thigh, navigating the blood vessels in the patient's body, and arriving at problem areas like the heart or brain. Once the distal tip of the catheter is precisely positioned inside the body, a microsurgical procedure like balloon angioplasty, stent placement, localized cauterization, or drug delivery can take place. With the reduced bodily reaction to microsurgery and the minimization of scar tissue, these procedures are highly preferred over more typical "macro" surgeries.

Method of minimizing damage to heart tissue during cardiac surgery and cardiac transplantation Inventor(s): Blevins, Roger D. ; (Apex, NC), Molina-Viamonte, Victor ; (Buenos Aires, AR), Mentzer, Robert M.

Prior to removing the heart from the body, adenosine or adenosine A.sub.1 or A.sub.3 receptor
Patents 293
agonists can be administered to the patient in a manner which provides cardioprotection to the heart. When the heart is removed from the body, it can be stored in a cardioplegic solution which contains adenosine, hypoxanthine and/or adenosine A.sub.1 or A.sub.3 receptor agonists. After the heart is reimplanted or transplanted, reperfusion injury can be minimized by administering adenosine or adenosine A.sub.2 receptor agonists to the patient in a manner which minimizes reperfusion injury. Preferably, all three steps are taken in order to minimize the amount of ischemic damage and reperfusion injury to the heart. Excerpt(s): This invention is generally in the area of minimizing ischemic damage and/or reperfusion injury to heart tissue during cardiac surgery where the heart is removed from the body and then re-implanted into the same body, as well as cardiac transplantation, where the heart is removed from one body and transplanted into another body... There are many surgical procedures for correcting complex congenital heart abnormalities, placing cardiac valvular prostheses, repairing defective valves, and bypassing obstructed coronary vessels which require the body to be supported with a heart-lung machine while the heart is rendered quiescent by interrupting its blood supply and briefly perfusing it with a cold solution of electrolytes with a relatively high potassium concentration (known as a cardioplegic solution). Placing the heart in a cardioplegic solution allows the surgeon to perform intricate surgical procedures on the heart without the distraction of having the heart pumping while the surgeon is operating, and the absence of blood also allows the surgeon to see more clearly... When the heart is placed in cardioplegic solution, the surgeon only has a limited amount of time to perform the surgery before irreversible ischemic damage is incurred. That amount of time is approximately 20 to 30 minutes. With the onset of ischemia, the supply of substrates for energy production ceases, and the high energy phosphate adenosine triphosphate (ATP) (which provides energy for contraction and operation of ion pumps in the myocardial cell) is degraded over time to its precursors ADP and AMP. AMP can undergo further degradation at the myocardial membrane to the diffusable purine nucleoside adenosine. Adenosine is also rapidly metabolized to inosine, hypoxanthine and xanthine. With the restoration of blood flow, these nucleosides are washed out of the heart via the circulation. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Invasive Cardiac Surgery of Atrial Fibrillation," the entire contents of which is hereby incorporated by reference... The present invention relates generally to medical devices and methods. More specifically, the invention relates to devices and methods for enhancing minimally invasive cardiac surgery of atrial fibrillation... Atrial fibrillation (AF) is a heart beat rhythm disorder (or "cardiac arrhythmia") in which the upper chambers of the heart known as the atria quiver rapidly instead of beating in a steady rhythm. This rapid quivering reduces the heart's ability to properly function as a pump. AF is characterized by circular waves of electrical impulses that travel across the atria in a continuous cycle. It is the most common clinical heart arrhythmia, affecting more than two million people in the United States and some six million people worldwide.

Methods and apparatus for determination and decrease of dynamic positioning errors of an ablating laser during refractive laser surgery Inventor(s): Teiwes, Winfried ; (Teltow/Berlin, DE), Weise, Ralf ; (Teltow/Berlin, DE), Huppertz, Michael ; (Teltow/Berlin, DE), Jacobs, Jorg ; (Teltow/Berlin, DE) Correspondence: THE FIRM OF KARL F ROSS; 5676 RIVERDALE AVENUE; PO BOX 900; RIVERDALE (BRONX); NY; 10471-0900; US Patent Application Number: 20030144651 Date filed: November 19, 2002 Abstract: The above described apparatus and methods provide the possibility to reduce or even eliminate the effects of delay between image acquisition and laser ablation. Thus this will lead to less positioning errors and therefore to better ablation results in laser refractive surgery. The importance of this invention will increase with decreasing ablating beam diameter. The use of synchronization leads to shorter delay times. Hence it follows that the duration of the whole treatment decreases as well. Excerpt(s): The present invention is directed to applications for improving vision with small- or large-spot scanning refractive laser surgery of the cornea, described in greater detail in Elander, R., Rich, L. F., Robin, J. B.: "Principles and Practice of Refractive Surgery"; W. B. Saunders Company, Philadelphia; 1.sup.st ed., 1997 and in Seiler, T.: "Refraktre Chirurgie der Hornhaut"; Thieme, Stuttgart; 1.sup.st ed., 2000. Here the corneal shape is adjusted by an aggregate of hundreds to thousands of laser shots in a pre-calculated ablation profile, according to the intended change of the corneal shape determined in a preceding diagnostic procedure. The temporal sequence of these laser shots is usually defined together with the ablation co-ordinates relative to the eye in a so-called shot-table before the laser treatment. During the surgery procedure the laser spot is positioned using a positioning device, for example a x-y scanner... Together, both delays can lead to considerable positioning errors of laser shots onto the eye due to the patient's eye movements: During fast eye movements (saccades) which exist during the surgery procedure (although the patient is urged to fixate on a point during refractive surgery procedure) a positioning error on the cornea of up to 2 mm can occur with a common overall delay time of 50 ms. Larger errors occur only in a few percent of all laser shots, however they can result in an inaccurate corneal shape, thus imperfect vision correction... The present invention provides methods and an apparatus for measurement and decrease of these dynamic positioning errors. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

The present application relates to a prosthesis for femur replacement surgery and more particularly to a prosthesis which receives a modular neck assembly selected for a desired neck length, neck angle, anteversion and offset... Surgery to replace the femur in total joint surgery involves the insertion of a stem in a cavity formed in the femur. The end of the stem extending from the cavity has a neck which is formed at an angle and the neck is mated with a socket in the hip. Every patient requires individual fitting due to the unique anatomical requirements of the particular patient. A prosthesis in which the stem and neck are a unitary device requires that the surgeon have a large quantity of prostheses available to provide a correct biomechanical function of the prosthesis with the patient. It is very costly to maintain a large inventory of prostheses and, despite the number of prostheses available, quite often the appropriate size and angle are not completely met.

Multifocal refractive surgery optimized to pupil dimensions and visual acuity requirements Inventor(s): Schelonka, Lee Paul ; (Lakewood, CO) Correspondence: LEE P. SCHELONKA; 3083 SOUTH OAK WAY; LAKEWOOD; CO; 80227; US Patent Application Number: 20030199858 Date filed: April 18, 2002 Abstract: Multifocal corneal refractive surgery for the correction of presbyopia is optimized, based on patient pupil measurements and acuity requirements. Measurements are made of the patient's pupil dimensions in bright and dim light, with near and distant focusing. A series of mathematical models of the wavefront transmitted through the eye/multifocal optic system is constructed, and the modulation transfer functions are calculated, for a series of optical zone dimensions and decentrations. The maximum resolvable spatial frequency and the expected visual acuity are calculated as functions of the zone dimensions and decentration. The patient's near and distant visual acuity requirements are compared to the expected visual acuity, and the optimized zone dimensions and decentration meeting the acuity requirements are determined. A required postoperative multifocal corneal profile is calculated. A computer-controlled laser, mechanical, thermal, or conductive device reshapes the cornea or a corneal implant. Nomograms are disclosed for centered, circular multifocal refractive surgery. Excerpt(s): This invention relates to the optics of the eye, the cornea, and refractive surgery. It specifies an improved method to create a multifocal cornea, with optical zone dimensions and decentration optimized, based on measurements of the patient's pupils and the patient visual acuity requirements. The refractive surgery corrects myopia, hyperopia, regular astigmatism and higher order aberrations, in addition to presbyopia... The visual acuity required by a patient depends on the visual tasks. For distant tasks such as driving, many patients require 20/20 acuity. The Snellen units of 20/20 correspond to a minimum angle of resolution of about one arc minute, a maximum resolvable spatial frequency of about 30 cycles per degree, and a decimal acuity of 1.0. However, many near visual tasks require a lower level of acuity. For example, reading seven point lowercase printed matter at a standard distance of 14
298 Surgery
inches (0.36 meters) requires only about 20 cycles per degree of angular resolution. This is equivalent to about 0.67 decimal acuity, or 20/30 distant acuity, and is termed Jaeger 2 or J2 near acuity... The visual acuity at near depends on accommodation, which is the eye's ability to change focus, and on the depth of focus of the eye. With age, the eye's ability to accommodate declines, resulting in presbyopia. Correcting for near vision requires additional optical power, increasing with increasing age, as in Table 1 (Ref Strauss). Between the ages of 40 and 60, an additional 1.0 Diopter of add power is required for each decade of life. The depth of focus of the eye, also termed pseudoaccommodation or apparent accommodation, is inversely proportional to the required visual acuity and depends also on the pupil diameter and the optics of the eye, including uncorrected refractive error and aberrations (Refs Green (1980) and Fukuyama). Conventionally, presbyopia has been treated with bifocal, trifocal or multifocal glasses or contact lenses. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

Viscous or viscoelastic agents used in surgery may perform a number of different functions, including without limitation maintenance and support of soft tissue, tissue manipulation, lubrication, tissue protection, and adhesion prevention. It is recognized that the differing rheological properties of these agents will necessarily impact their ability to perform these functions, and, as a result, their suitability for certain surgical procedures. See, for example, U.S. Pat. No. 5,273,056... Cataracts are opacities of the ocular lens which generally arise in the elderly. In order to improve eyesight, the cataractous lens is surgically removed and an artificial intraocular lens is inserted in its place.

Ophthalmic apparatus and corneal surgery apparatus Inventor(s): Fujieda, Masanao ; (Toyohashi-shi, JP) Correspondence: RADER FISHMAN & GRAUER PLLC; LION BUILDING; 1233 20TH STREET N.W., SUITE 501; WASHINGTON; DC; 20036; US Patent Application Number: 20030120266 Date filed: December 2, 2002 Abstract: An ophthalmic apparatus for obtaining differences between the pupil positions in photopia and scotopia accurately, and a corneal surgery apparatus for ablating a cornea of an eye by laser beam irradiation allowing for the differences. The ophthalmic apparatus has devices for inputting a first image of an anterior eye segment in photopia and a second one in scotopia, for obtaining pupil information in the images and differences between the pupil information in photopia and that in scotopia, and for outputting the differences. The corneal surgery apparatus has devices for irradiating the cornea with a laser beam, for aligning an irradiation position with the eye, for inputting differences between the pupil positions in photopia and scotopia, for detecting the photopic pupil position, for obtaining an alignment position of the laser beam based on the pupil position and the positional difference, and for controlling the alignment device based on the alignment position. Excerpt(s): The present invention relates to an ophthalmic apparatus and a corneal surgery apparatus used in ophthalmic clinics and the like... On ophthalmic diagnosis, examination, treatment and prescription, it is sometimes necessary to obtain information about the position and/or shape of a pupil. For example, in corneal surgery for correcting refractive power by ablating a cornea with a laser beam, it is common practice to align a reference axis of irradiation of the laser beam with the position of a pupil center... In addition, among multifocal contact lenses, in which different lens diopters are provided in the form of concentric circles around an axis of an optical center of the lens, there are some in which the axis of the optical center is decentered with respect to the geometric center of the lens. The amount of the decentering is determined in consideration of the pupil center position. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Coronary artery disease remains the leading cause of morbidity and

mortality in Western societies. Coronary artery disease is manifested in a number of ways. For example, disease of the coronary arteries can lead to insufficient blood flow resulting in the discomfort and risks of angina and ischemia. In severe cases, acute blockage of coronary blood flow can result in myocardial infarction, leading to immediate death or damage to the myocardial tissue. A number of approaches have been developed for treating coronary artery disease. In less severe cases, it is often sufficient to treat the symptoms with pharmaceuticals and lifestyle modification to lessen the underlying causes of disease. In more severe cases, the coronary blockages can often be treated endovascularly using techniques such as balloon angioplasty, atherectomy, laser ablation, stents, hot tip probes, and the like. In cases where pharmaceutical treatment and/or endovascular approaches have failed, or are likely to fail, it is often necessary to perform a coronary artery bypass graft (CABG) procedure.

The solution may be used in any surgery where the heart must be arrested, but it is particularly useful in cardiopulmonary bypass surgery. Because the solution relies primarily upon pyruvate to protect the heart from damage during and immediately after arrest, other additives are not as necessary as with current cardioplegia solutions or are not necessary at all. The invention also includes a method for making the cardioplegia solution and a process of performing cardiopulmonary bypass surgery using the novel cardioplegia solution. Excerpt(s): This invention concerns a novel pyruvate-containing cardioplegia solution and its use for arresting and preserving the heart during heart surgery. To arrest the heart, the solution is introduced into the heart's coronary blood vessels. Chemical components of the solution protect the heart from injury and preserve heart muscle tissue throughout the period of cardiac arrest, allowing for improved post-surgical recovery of the heart's contractile performance as compared to lactate or glucose-based solutions currently used in the art... Heart surgeries, such as coronary artery bypass grafting, valve replacement and repair of structural defects of the heart, are delicate procedures demanding a high level of surgical precision. It is typically necessary to temporarily stop the heart beat during these procedures so that the organ remains motionless, thereby facilitating the surgeon's work. The heart beat is arrested by introducing into the heart's coronary blood vessels special aqueous solutions, termed cardioplegia solutions, which contain chemicals that interrupt the physiological processes that cause the heart to beat... A mechanical pump assumes the heart's role of supplying blood to the rest of the body while the heart is arrested. However, the heart's own coronary blood flow is interrupted during cardiac arrest and is not restored by the mechanical pump; the heart becomes ischemic. Coronary blood flow is critical because it supplies the heart with the fuels and oxygen it needs to generate ATP, the heart's main
Patents 303
source of chemical energy. ATP supplies energy for numerous cellular processes that enable the heart to pump blood and which sustain the cells of the heart muscle. Cardiac arrest minimizes the heart's energy demands by interrupting the major energyconsuming process, that of pumping blood, but some energy is still required to support other cellular functions. Consequently the heart's energy reserves are depleted, albeit slowly, during cardiac arrest, due to the lack of coronary blood flow. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

A distal end of the articulated arm receives a contact member and the contact member is moveable relative to the distal end. A surgeon may configure the support arm assembly to contact a desired portion of a heart and fix the articulated arm, its axial position, its rotated position and the orientation of the contact member with a single control. Excerpt(s): The present invention relates generally to surgical tools including surgical tools for cardiac surgery, and more specifically to surgical tools used in conjunction with Coronary Artery Bypass surgery, both the on-pump and the off-pump variety... OffPump Coronary Artery Bypass (OPCAB) has evolved since about 1990, following the pioneering work done in North America by Ankeney in the period 1970-75, Akins et al. 1979, and Fanning et al. 1979-1992 in the U.S, and by Trapp & Bisarya in the early 1970's in Canada. In South America other pioneering was done by Benetti (1978-85) in Argentina and Buffolo (1981-85) in Brazil. Generally the anastomotic site was immobilized with stay sutures, such as the technique described by Trapp & Bisarya, who encircled the anastomotic area with sutures placed deep in the myocardium to incorporate enough muscle to suspend the heart yet prevent damage to the coronary artery. Later in the U.S. Phister (1985-90) and Gundry in 1990 (among others) performed OPCAB surgery but both had an assistant with a hand held instrument press on the surface of the heart near the anastomotic site to aid in epicardial immobilization... In the mid 1990's various epicardial stabilizing instrument that could be attached to sternal retractors were evolved. For example U.S. Pat. No. 5,836,311 described a vacuum epicardial stabilizer, U.S. Pat. No. 5,786,746 described an adhesive coated and vacuum epicardial stabilizer, and U.S. Pat.

The pillow comprises an elongated, self-sustaining, flexible body unit of compressible material having shape return memory. The body unit is provided with an indented upper face defined by a longitudinally extending, centrally located channel and chamfered downwardly inclined patient positioning surfaces on opposite sides of the central channel. Converging, inclined side surfaces of the body unit are configured and strategically located to accommodate the axilla areas of a patient while the patient is supported on the body unit. A removable cover that substantially conforms to the configuration of the body unit is provided in full covering relationship to the body unit. Excerpt(s): This invention relates to an improved surgical pillow especially adapted to support, cushion and position a patient while in a prone position on an operating table during rectal surgery... At the present time, positioning of a patient for rectal surgery on a conventional operating table is most usually accomplished by making up rolls of blankets, towels or other similar items which are then placed along opposite sides of the patient's torso. That technique has many disadvantages including the tendency for the rolled support to shift and tend to be displaced from the original patient supporting locations thereof, and the fact that the rolls do not provide optimum patient cushioning and positioning. Furthermore, it is difficult to arrange the blanket or towel rolls in this position such that the patient's arms can be placed comfortably hanging over the edges of the operating table. Equally as significant, although support is provided by the rolls, blanket or towels for the patient's torso, the patient is still lying flat on the table in a prone positions such that pressure is inherently applied to the central part of the patient's body. The result is a tendency for the compressive forces on the patient's torso to impede veinous blood return to the patient's heart... Efforts to solve the problem of providing comfortable and effective support and positioning of a patient in a prone position during rectal surgery have not found widespread acceptance and universal usage in part because of the complexity and cost of prior devices, the inability of the supporting devices to adequately accommodate patients of different sizes and weights, and the inordinate setup and adjustment time encountered with certain units.

Abstract: A surgery center includes a matrix of flow patterns and interaction nodes that are optimized by providing a physical structure that includes an admit/reception node, a pre-operative node, a surgical node, an acute recovery node and an observation node. The pre-operative node is located adjacent the admit/reception node. The surgical node is located adjacent the pre-operative node. The acute recovery node is located adjacent to the surgical node and between the surgical node and the observation node. The patient flow throughout each of the nodes is unidirectional. An instrument flow is circular and confined to the surgical node, a staff/physician flow includes a separate entry to the surgery center separate from the admit/reception node and the observation node, a supply flow is linear, and an environmental waste flow includes transitioning between a sterile zone and a non-sterile zone. The patient flow, the instrument flow, the staff/physician flow, the supply flow and the environmental waste flow intersect at the surgical node.

The laser refractive surgery (or laser keratectomy) field has rapidly grown over the past few years with many new lasers and algorithms to correct

human vision. Systems are now using laser wavelengths from the ultraviolet (excimer) to the infrared to change the shape of the cornea in a calculated pattern which makes it possible for the eye to focus properly. For example, in the treatment of myopia, the excimer laser is used to remove or ablate tissue from the cornea in order to flatten its shape. Infrared (IR) energy is also used by some companies to treat myopia by reshaping the corneal tissue by a "thermal" method as opposed to ablation with the excimer wavelength. The correction of hyperopia is produced by steepening the cornea by removing tissue at the outer edges of the cornea (excimer) or by reshaping the cornea at the outer edges (IR energy). The correction of astigmatism, both myopic and hyperopic, requires the laser to remove or reshape tissue in a more complex pattern. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •

The subject systems include a temperature sensor for application to the organ, reservoirs for containing temperaturecontrolled fluids to be delivered to the organ, a temperature regulator for regulating or maintaining the temperatures of such fluids, a pump for transferring the fluids from the reservoirs to the organ, a display for displaying certain system operating parameters and other information, a user interface module and a controller for controlling the functions of the system based on certain system operating parameters. The subject methods generally involve monitoring the temperature of an organ and, based on the organ's temperature, controlling the application of temperature-controlled fluids to the organ. Excerpt(s): The present invention is related to systems and methods for monitoring and controlling the temperature of an organ or an internal portion of the body during surgery... During surgery it is often desirable or necessary to maintain an organ or a portion of the body at a certain temperature. For example, in open-heart surgery wherein cardiopulmonary bypass is employed, a cold solution having a temperature of about 4.degree. C. is delivered under controlled conditions to the coronary arteries via the aortic root. The solution arrests the contractions of the heart through chemical action, supplies the heart muscle with oxygen and also cools the heart to a temperature typically in the range from about 10.degree. to 14.degree. C. in order to minimize deterioration of the heart muscle during the surgery. This cold solution includes cardioplegia which is a crystalloid chemical solution containing potassium and other additives. Depending on surgeon preference and the progress of the surgery, the solution may be comprised of 100% cardioplegia ("cold cardioplegia") or some mixture of cardioplegia and blood ("warm cardioplegia"). The temperature and application of the cardioplegic solution is typically controlled by the heart-lung machine... Due to many of the drawbacks of temperature monitoring and temperature control and
Patents 307
regulation of the heart during surgery, there is continued interest in the development of new devices and techniques for monitoring and controlling the temperature of organs during surgery. Of particular interest would be the development of systems and methods wherein the monitoring and controlling of an organ's temperature during surgery is continuous and automatic, thus obviating the need for physician intervention. It would be additionally beneficial if such system and method were applicable to both stopped and beating heart surgeries, and in both open and minimally invasive surgeries.

Universal hand surgery table Inventor(s): Ames, Elliot L. ; (Cherry Hill, NJ) Correspondence: WOODCOCK WASHBURN LLP; ONE LIBERTY PLACE, 46TH FLOOR; 1650 MARKET STREET; PHILADELPHIA; PA; 19103; US Patent Application Number: 20030192122 Date filed: May 27, 2003 Abstract: A hand surgery table has a top for supporting a patient's arm during hand surgery. A concave end of the hand surgery-table accommodates the attending surgeon's torso so that the attending surgeon may sit comfortably. A tongue-shaped end portion extends from the end opposite the concave end for securing the hand surgery table to a conventional operating table where the patient may lie and rest his or her forearm on the hand surgery table top. Elbow support structures are attached to respective sides of the hand surgery table and have convex peripheries for the attending surgeon and the nurse assistant to rest their elbows and forearms. The elbow support structures are retractable to the underside of the table and are moveable longitudinally along the hand surgery table. Excerpt(s): This invention relates to an operating table for use in hand surgery... Hand surgery tables have been used in the medical field to perform surgery on a patient's hand for many years. Conventional hand surgery tables utilize rigid elbow support structures attached in a fixed manner to respective sides of the hand surgery table. The attending surgeon and the nurse assistant utilize the elbow support structures to rest their elbows during the surgical procedure... Conventional elbow support structures are not pivotable or retractable underneath the hand surgery table. The elbow support structures have a tendency to get in the way during surgery or afterwards when the hand surgery table is detached from a conventional operating table for storage. Additionally, the elbow support structures are rectangularly shaped and boxy and do not permit the attending surgeon or the nurse assistant to sit comfortably at the hand surgery table. Further, the elbow support structures are hard and not cushioned, making it uncomfortable for the attending surgeon to rest his elbows. All of these problems tend to impair the attending surgeon's and the nurse assistant's comfort, maneuverability, and performance during hand surgery on a patient.

This is achieved by using specifically designed surgical drapes for the viewing monitor and apparatus designed to unobtrusively position the viewing monitor within the surgical field... Surgery on the heart is one of the most commonly performed types of surgery that is done in hospitals across the U.S. Cardiac surgery can involve the correction of defects in the valves of the heart, defects to the veins or the arteries of the heart and defects such as aneurysms or thromboses that relate to the circulation of blood from the heart to the body. In the past, most cardiac surgery was performed as open-chest surgery, in which a primary median sternotomy was performed. That procedure involves vertical midline skin incision from just below the super sternal notch to a point one to three centimeters below the tip of the xiphoid. This is followed by scoring the sternum with a cautery, then dividing the sternum down the middle and spreading the sternal edges to expose the area of the heart in the thoracic cavity. This technique causes significant physical trauma to the patient and can require one week of hospital recovery time and up to eight weeks of convalescence. This can be very expensive in terms of hospital costs and disability, to say nothing of pain to the patient. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html

Wicking instrument for LASIK surgery Inventor(s): Feinsod, Matthew ; (Grear Neck, NY) Correspondence: FROMMER LAWRENCE & HAUG; 745 FIFTH AVENUE- 10TH FL.; NEW YORK; NY; 10151; US Patent Application Number: 20030120226 Date filed: December 3, 2002 Abstract: An apparatus and method are provided for use in removing liquid from under a corneal flap generated during LASIK surgery. The apparatus comprises a handle, a sickle-shaped end coupled to the handle, the sickle-shaped end having a concave and a convex portion, and a sponge coupled with the concave portion of the sickle-shaped end, extending along the convex portion thereof, and being shaped substantially similarly to the sickle-shaped end. The sickle-shaped end extends from approximately 180.degree. to 270.degree., or any other desired part of a circle and may have sponge on one or both sides thereof. The radius of the sickle-shaped end is the same or slightly larger than the diameter of a corneal flap generated during LASIK surgery so that when the apparatus is placed adjacent the cornea of a patient about the corneal flap, liquid is wicked from thereunder without requiring any contact with the corneal flap. Excerpt(s): Refractive eye surgery is a general term for a surgical procedure intended to improve or correct the focus of a patient's eyes by changing the shape of the eye, thereby changing the optics by which the eye sees various images. While surgeries reshaping various portions of a patient's eye have been employed for some time, most recently, refractive eye surgery has involved reshaping the cornea of a patient's eye... The cornea is the clear, front surface of the eye of a person which refracts, or bends light as it enters the eye. This light that is bent by the cornea is focused on the retina of the eye. The retina is a layer of light-sensitive cells that lines the back of the eye. The retina converts light rays incident thereon into electrical impulses. These electrical impulses are sent through the optic nerve of the person to his or her brain. In the brain, these impulses are interpreted as images. If images received by the eye and refracted or bent by the cornea are not properly focused on the retina, the eye is said to have a refractive error. Myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism (distortion at both near and far distances) are terms used to describe the refractive error of an eye. These refractive errors are the result of various irregular corneal curvatures, lens curvatures, or axial eye lengths that prevent images from being focused to a single point on the eye's retina... In performing refractive eye surgery, an excimer laser (excited dimer) may be used to reshape the cornea, thereby enabling the cornea to properly focus received light on the retina. The excimer laser interacts with the corneal tissue of the eye utilizing a laser-tissue interaction called photoablation. In photoablation, ultraviolet laser pulses precisely etch the cornea by uncoupling various intermolecular bonds thereof, thereby removing a submicron layer of cornea under highly controlled conditions. Because there is a relative absence of thermal injury to the corneal tissue during this procedure, the corneal cells can be ablated without opacifying (rendering so that light cannot pass therethrough) adjacent tissue. Such opacification might result in the inability to see through the opacified tissue of the eye. By carefully controlling the number of pulses of the ultraviolet laser, and the diameter and location of each pulse, the corneal tissue of a patient can be resculpted as necessary in order to improve the patient's vision.

In addition to LOCATORPlus, in collaboration with authors and publishers, the National Center for Biotechnology Information (NCBI) is currently adapting biomedical books for the Web. The books may be accessed in two ways: (1) by searching directly using any search term or phrase (in the same way as the bibliographic database PubMed), or (2) by following the links to PubMed abstracts. Each PubMed abstract has a "Books" button that displays a facsimile of the abstract in which some phrases are hypertext links. These phrases are also found in the books available at NCBI. Click on hyperlinked results in the list of books in which the phrase is found. Currently, the majority of the links are between the books and PubMed. In the future, more links will be created between the books and other types of information, such as gene and protein sequences and macromolecular structures.

[email protected]. Website: www.vestibular.org. PRICE: $34.95 plus shipping and handling. ISBN: 0963261142. Summary: Benign paroxysmal positional vertigo (BPPV) is an inner ear balance disorder characterized by sudden brief bouts of intense vertigo (a sensation of spinning dizziness) and nystagmus (rapid eyeball movements) induced by specific head movements. This chapter on surgery for BPPV is from a book that was written for people who have or suspect they have BPPV and who want to know more about its nature, causes, diagnosis, and treatments as well as strategies for coping with its effects. The author explains that the majority of people with BPPV will never have inner ear surgery; they will either improve on their own or while undergoing one medical (non surgical) treatment or another. Physicians look at a number of different factors to determine if surgery would be an appropriate treatment option; factors can be divided into three groups: patient, physician, and general. The chapter lists suggested questions for patients to ask their doctors, and offers strategies to help in the decision making process about surgery. The author then describes the types of surgeries that may be performed, including posterior semicircular canal occlusion, singular neurectomy (nerve section), and utricular macular ablation. For each type, the author describes the procedure, postoperative recovery, success rates, possible reasons for failure, and potential complications. The book is published by the Vestibular Disorders Association (VEDA), a nonprofit organization that provides information and support to people with inner ear disorders. 1 figure. 21 references.

Vocal Fold and Laryngeal Surgery Source: in Thurman, L. and Welch, G., eds. Bodymind and Voice: Foundations of Voice Education, Volumes 1-3. 2nd ed. Collegeville, MN: VoiceCare Network. 2000. p. 620-631. Contact: Available from National Center for Voice and Speech (NCVS). Book Sales, 334 Speech and Hearing Center, University of Iowa, Iowa City, IA 52242. Website: www.ncvs.org. PRICE: $75.00 plus shipping and handling. ISBN: 0874141230. Summary: Microsurgery on the vocal folds sometimes becomes the only option available to restore or optimize the sound quality or capabilities of a person's voice. This chapter on vocal fold and laryngeal surgery is from a multi-volume text that brings a biopsychosocial approach to the study of the voice. The authors use the phrase 'bodyminds' to describe the interrelationship of perception, memory, learning, behavior, and health, as they combine to affect all environmental interactions, adaptations, and learning. The books are written for teachers, voice professionals, people who use their voices on an avocational basis, and interested members of the general public. This chapter uses the term phonosurgery for voice restorative surgery. The most common mucosal disorders for which such surgery may be appropriate are polyps, cysts, capillary ectasia, and nodules that have been treated therapeutically for a considerable time, with complete patient cooperation, and they have not resolved. Treatment for these disorders is discussed in the first section; other kinds of phonosurgery, including
Books 333
vocal fold injections and laryngeal framework surgery, are discussed in the latter section. The chapter is written primarily in question and answer format, with the goal of answering common questions that readers may have about vocal fold surgery. The author concludes that it is important to maintain a positive outlook on how the voice will be healthier and more capable after healing and reconditioning. 29 references. •
Cochlear Implant Surgery: What Parents Need to Know Source: in Estabrooks, W., ed. Cochlear Implants for Kids. Washington, DC: Alexander Graham Bell Association for the Deaf. 1998. p. 47-57. Contact: Available from Alexander Graham Bell Association for the Deaf. 3417 Volta Place, NW, Washington, DC 20007-2778. (202) 337-5220. PRICE: $42.95 plus shipping and handling. ISBN: 0882002082. Summary: This chapter discusses the information that parents need to know about cochlear implant surgery in young children. The chapter is from a book that brings together experts from the fields of education, medicine, and related disciplines to provide an overview of cochlear implants for the pediatric population. The author stresses that the actual surgery occupies but a small percentage of the total time taken up by the testing, evaluation, stimulation, programming, and rehabilitation of the child, yet the surgical period is a time of anxiety, great tension, and potential risk. If the surgery is not correctly performed, the child may suffer complications or the implant may not function properly. Topics include preparing for the surgery, going to the hospital, how the operation is performed (the surgical techniques used), the risks of the surgery, the postoperative period, taking the child home, the healing period, activity and other limitations, longterm considerations, and device failures. The author encourages parents to take an active role in preparing their child for cochlear implant surgery to help maximize the chances of a successful outcome. 2 figures.

[email protected]. Website: www.singpub.com. PRICE: $325.00 plus shipping and handling. ISBN: 1565937287. Summary: Phonosurgery, or aesthetic surgery of the vocal organ, became an accepted surgical modality in the late 1950s and early 1960s when the entire field of surgery experienced an interest in procedures for functional improvement. This chapter, from a book on the clinical care of the professional voice, reviews the history of phonosurgery. Phonosurgery includes any surgery designed primarily for the improvement or restoration of the voice. Topics include phonosurgery in vocal fold paralysis, microsurgical techniques for phonosurgery, the leading surgeons in the field, phonosurgery of the laryngeal nerves, phonosurgery for spastic dysphonia, phonosurgery after laryngectomy, phonosurgery of the laryngeal framework, and transplants in phonosurgery. The author concludes that only in the last 30 years have concerted efforts by surgeons in the U.S., Japan, and Germany established reliable and effective procedures for transforming the human voice. The chapter includes photographs of many of these leaders. 30 figures. 36 references.

Summary: This chapter, from a book on the clinical care of the professional voice, reviews the history and development of phonomicrosurgery. In the 20th century, a variety of technological developments improved direct examination of the larynx, such as improved laryngoscopes, hand instruments, and lighting, as well as the surgical microscope, the carbon dioxide laser, and general anesthesia. Through the last two decades, there has been a greater understanding of the physiology underlying vocal fold oscillation. These principles have been joined with the technological developments of microlaryngeal surgery and have led to current concepts of phonomicrosurgery. Topics covered in this chapter include the prelaryngology era of indirect mirror laryngoscopy, the origin of laryngology, transoral management of larynx cancer and Crown Prince Frederick, the era of direct surgical laryngoscopy, microlaryngoscopy, the body cover theory of voice production, and current concepts in phonomicrosurgery. 22 figures. 127 references.

[email protected]. Website: www.singpub.com. PRICE: $325.00 plus shipping and handling. ISBN: 1565937287. Summary: This chapter, from a book on the clinical care of the professional voice, reviews the current thinking regarding voice surgery. Most surgical procedures for voice disorders can be performed endoscopically, obviating the need for external incisions and minimizing the amount of tissue disruption. The author stresses that, when endoscopic visualization is not adequate because of patient anatomy, disease extent, or other factors, the surgeon should not compromise the results of treatment or risk patient injury by attempting to complete an endoscopic procedure. Topics include patient selection and consent, documentation (preoperative assessment), timing of voice surgery, indirect laryngoscopy, direct laryngoscopy, anesthesia (local and general), instrumentation, laryngeal microsurgery, contact endoscopy, vocal fold cysts, vocal fold polyps, varicosities and ectatic vessels and vocal fold hemorrhage, Reinke's edema, granulomas and vocal process ulcers, papillomas, ventricular fold cysts, epiglottic cysts, laryngoceles, miscellaneous masses, sulcus vocalis, laryngeal webs, bowed vocal folds, presbyphonia, vocal fold paralysis and framework dysfunction, Teflon injection, Gelfoam injection, collagen injection, autologous fat injection, removal of Teflon, thyroplasty, nomenclature, arytenoid adduction or rotation, nerve anastomosis, nerve muscle pedicle surgery, arytenoid reduction for arytenoid dislocation, arytenoidectomy, voice rest, and related surgery, including that for velopharyngeal insufficiency and obstructive sleep apnea syndrome in professional voice users. 31 figures. 1 table. 99 references.

Cosmetic surgery encompasses any plastic surgical procedure or set of procedures used to enhance appearance. This chapter, from a book on the clinical care of the professional voice, discusses facial plastic surgery in professional voice users. Many singers also play musical instruments, so the authors include a few additional comments to highlight selected effects of facial plastic surgery on instrumental performance. Topics include general considerations, such as the choice of surgeon, procedures, limitations, and financial concerns; and special considerations, including anesthesia and effects on voice and instrumental performance. A final section discusses the role of the rehabilitative team. The authors conclude that if all questions and concerns are dealt with preoperatively, safe and effective cosmetic surgery can be accomplished in the professional voice user population. 2 tables. 3 references.

Joint Surgery in Ehlers-Danlos Patients: Results of a Survey Source: Loose Connections. XV(1): 1,8-9,11. February-March 2000. Contact: Available from Ehlers-Danlos National Foundation. 6399 Wilshire Blvd., Suite 510, Los Angeles, CA 90048. (323) 651-3038. Summary: This newsletter article provides health professionals and people who have Ehlers-Danlos syndrome (EDS) with information on a study that evaluated the success rates, complication rates, and satisfaction rates of surgical procedures in patients who have it. EDS, a rare, hereditary, connective tissue disorder is characterized by joint hypermobility, skin extensibility, tissue fragility, and a bleeding diathesis that result from flawed collagen cross linking. The study population consisted of 44 patients who responded to a survey about joint problems related to shoulders, elbows, knees, and ankles. They were asked to categorize the procedures that they underwent for these joints into primary indications of improved stability, pain reduction, or improved range of motion. A total of 214 procedures were performed on 95 joints. Several procedures had multiple indications, and each indication was addressed separately. Thus, there were 240 indications for 214 surgical procedures. The respondents indicated that they thought the preoperative goals were met in 53 percent of all indications. Specific success rates were 50 percent in the stabilization procedures, 50 percent in the pain reducing procedures, and 100 percent in the range of motion procedures. Wound healing problems were reported in 11 percent of all procedures. The article concludes that the study demonstrates that problems with surgical procedures in patients with EDS may be high relative to other populations without connective tissue disorders. More study is needed in this patient population to validate the results in a larger cohort. 5 tables and 20 references.

Contact: Available from Mayo Foundation for Medical Education and Research, 200 First Street SW, Rochester, MN 55905. (800) 291-1128 ext. 250. Summary: This newsletter article provides people who have back pain with information on the use of surgery to relieve pain. Most back problems respond to nonsurgical treatments, so surgery is usually reserved for problems in which a nerve is severely pinched, the spinal cord is compressed, or the spine is unstable. Back problems that have the best chance of being helped by surgery include herniated disk, back pain caused by disk degeneration, spinal stenosis, fractures, infections and tumors, and spinal deformity. The most common types of back surgery are laminotomy or laminectomy, diskectomy, and fusion. Laminotomy or laminectomy involves removing a small amount of the lamina. Diskectomy involves the removal of a portion of a disk to relieve pressure on a nerve. Spinal fusion permanently connects two or more bones in the spine. Less invasive surgical techniques include endoscopic procedures, vertebroplasty, kyphoplasty, intradiskal electrothermal therapy, and use of bone substitutes. 2 figures. •

[email protected]. Summary: This newsletter article provides people who need total knee replacement with information on this surgical procedure. Severe, intractable pain from osteoarthritis is the most common reason for total knee replacement. However, individual circumstances and expectations about pain and mobility have as much to do with the decision to undergo total knee replacement as the condition itself. The article describes the anatomy of the knee, discusses the materials used in knee replacements, and explains the procedure used. The knee is accessed through an incision made down the front of the leg from mid thigh to several inches below the knee. The ends of the femur and top of the tibia are removed. Then the menisci are removed and the anterior cruciate ligament is cut. The posterior cruciate ligament may also be cut. The patella may either be left intact or have the inside resurfaced. Knee replacements come in three main parts: a femoral component, a tibial component, and a disc that fits on top of the tibial component. Although progress varies, most people do not feel completely recovered from knee replacement surgery for a full year or more. 1 figure.

[email protected]. Summary: This newsletter article provides people who have arthritis in the elbow with information on the use of a surgical technique known as debridement to relieve elbow pain and improve function and motion. The most common types of arthritis are osteoarthritis, which is a degenerative disease, and rheumatoid arthritis, which is associated with inflammation of the lining of joints. When treatments such as medications, activity modification, and physical therapy no longer help, for arthritis pain and immobility, surgery may be needed. Joint replacement is the standard of care for people who have advanced arthritis in the elbow. However, some people with an earlier stage of disease may have the option of undergoing traditional or arthroscopic

debridement. Although debridement is traditionally performed with an open incision, arthroscopic surgery is proving promising. One form of arthroscopic debridement is known as osteocapsular arthroplasty. The article outlines the characteristics of people who may benefit from arthroscopic debridement and highlights the risks associated with it. 1 figure. •

[email protected]. Summary: This newsletter article provides women who need hip replacement surgery with information on this procedure. People who are candidates for this surgery include those who have severe pain resulting from osteoarthritis, rheumatoid arthritis, injury, or bone tumors. A physician may suggest that a patient try other less invasive options before considering hip replacement surgery. If these options fail, surgery may be recommended. The procedure involves removing the head of the femur and the socket, inserting a metal ball and stem into the femur, and placing a cup made of metal and plastic in the socket. The artificial hip is then fixed in place, muscles and tendons are returned to their proper position, and the incision is closed. The article explains postoperative care procedures and highlights possible complications, including infection, hip dislocation, blood clots, prosthetic loosening or breakage, and inflammation. The article also includes precautions that patients should take following surgery. 3 figures.

[email protected]. Summary: This newsletter article provides people who may need a surgical procedure with information on laser surgery. Laser is a acronym that stands for light amplification by stimulated emission of radiation. Laser beams are strong beams of light produced by electrically simulating a solid, liquid, or gas. Lasers are usually named for the substances that produce them. Uses include cutting or destroying abnormal or diseased tissue, shrinking or destroying tumors or lesions, burning off or vaporizing tissue, sculpting tissue, and sealing bleeding blood vessels. Lasers have some distinct advantages over traditional methods, such as causing minimal bleeding, posing less risk of infection, causing minimal scarring, and being faster than traditional surgery. However, in many cases, conventional surgery is more effective than laser surgery, and laser surgery is not necessarily pain free or risk free. The article discusses common uses of laser surgery in dermatology, plastic surgery, ophthalmology, gastroenterology, gynecology, urology, cardiology, neurosurgery, dentistry, otorhinolaryngology, and orthopedics.

Summary: This newsletter article reports on the incidence of headaches after acoustic neuroma surgery. The author notes that although headaches as a symptom prior to treatment are relatively uncommon for vestibular schwannoma, they occur with surprising frequency after treatment and can have a profound impact upon quality of life in acoustic neuroma patients. The pain often persists for prolonged periods of time and does not always respond well to a number of medical and surgical treatments directed at the headache. The author discusses the frequency of headache following neuroma surgery, the nature of the headache, their causes, and current therapies. Causes of the headaches can include the surgical approach (craniectomy versus craniotomy), aspetic meningitis, muscle pain, nerve entrapment, and low cerebrospinal fluid pressure. The best treatment is prevention, since these headaches have proven to be difficult to treat once they occur. The author also discusses the use of cranioplasty, medication, local therapy to neck muscles, nerve block or section, stress reduction and antidepressants, and care from a multidisciplinary pain center. The author notes that most surgeons are aware of the need to prevent these headaches and take measures to minimize muscle incisions, to replace skull bone whenever possible, and to limit the distribution of bone dust within the operative field.

hospital stay, and discharge from the hospital (going home). The author stresses that patients who begin treatment with a positive mental attitude and who maintain that attitude throughout the recovery period seem to have an easier and more complete recovery. Readers are advised to talk with a former patient about his or her experiences; often it is helpful to hear how others have coped with having had an acoustic neuroma. •
Facial Weakness and Facial Paralysis Following Acoustic Neuroma Surgery Source: ANA Notes. Number 74: 1, 4-5. June 2000. Contact: Available from Acoustic Neuroma Association (ANA). 600 Peachtree Parkway, Suite 108, Cumming, GA 30041-8211. (770) 205-8211. Fax (770 www.ANAUSA.org. Summary: This newsletter article describes the facial weakness and facial paralysis that can follow surgery for acoustic neuroma. The article is a reprint of the lecture given by the author at ANA's 14th National Symposium in Milwaukee, Wisconsin. The author discusses four primary causes for facial weakness following this type of surgery: traction, heat, loss of blood supply, and transection of the nerve. The first three result in a temporary facial weakness; however, transection of the nerve can result in a permanent facial paralysis unless secondary procedures are then performed. The author describes some approaches to the immediate postoperative period, including the use of artificial tears and lubricant in the ear (to protect the cornea), oral guards to protect the inside of the upper cheek, and weighing the upper eyelid to assist in eye closure. The author also describes the reparative surgery that may be undertaken in patients who no longer have a facial nerve, or whose facial nerve is transected. Observation only is the treatment for patients whose nerve was anatomically preserved and who are likely to regain facial movement. The author cautions that it can take from one month to one year for the nerve to regenerate (grow back). The article concludes with a reprint of a brief question and answer session that the author conducted after giving this lecture; topics covered include the use of Botox, free tissue transfer, the use of facial retraining, testing the amount of moisture in the eye, and patient selection for secondary surgical procedures.

Summary: Stereotactic radiosurgery (SRS) is a minimally invasive procedure that delivers a large, one-time dose of radiation to a specific target within the head, while sparing surrounding tissue. This newsletter article discusses radiosurgery, an attractive alternative for some acoustic neuroma patients. Obvious advantages are its noninvasive nature, its shortened immediate recovery time, its preservation of hearing in many cases, and its value as an alternative for patients unable or unwilling to undergo surgery. The authors describe the procedure and its development, a typical radiosurgical treatment, and what the patient can expect as results from this type of surgery. The authors caution that the role of radiosurgery is limited by its inability to remove excess weight from the brainstem immediately. Therefore, patients with large, symptomatic tumors should undergo conventional surgery in order to decompress the brainstem more quickly. However, for acoustic neuromas under 3 cm in diameter, the results of SRS compare favorably with the best published surgical results. Hearing preservation rates of 70 percent have been reported for very small tumors. 2 figures.

Laparoscopic Surgery for the Treatment of High Anorectal Malformations Source: PTN News. 11(1): 1-3. February 2002. Contact: Pull-thru Network (PTN). 2312 Savoy Street, Hoover, AL 35226-1528. E-mail:
[email protected]. Website: www.pullthrough.org. Summary: This newsletter article reviews the use of laparoscopic surgery for the treatment of high anorectal malformations. To treat diseases or abnormal anatomy, pediatric surgeons have traditionally had to dissect through normal tissue in order to provide adequate surgical exposure. However, new minimally invasive surgical techniques have revolutionized many procedures, including anorectal pull-through in infants. This approach involves the use of a laparoscope (an instrument used to see inside the body through a small incision) as well as trocars (instruments used to puncture the wall of a body cavity). Laparoscopic magnification and illumination enhances surgical exposure and anatomic visualization. The use of trocars creates small puncture wounds rather than the much large incisions required in traditional open surgery, thus reducing the likelihood of complications such as infection, wound breakdown, and physiologic stress to the infant. The article reviews the anatomy and physiology of normal bowel continence, the classification of anorectal malformations, the rationale for the laparoscopically assisted anorectal pull-through (LAARP), special considerations for coexisting medical conditions, the three-stage surgical approach, and the outcomes that can be expected from traditional open surgery compared with LAARP. The contact information for the author and for a pediatric nurse practitioner who is a colleague of the author, is provided for readers with additional questions. 1 reference.

Summary: This newsletter article answers a question from a reader who is coping with gastroesophageal reflux disease (GERD, the return of stomach acid back into the esophagus) and a hiatal hernia. The reader has been advised to have surgery for the hernia and is interested in finding out the impact of surgery on the GERD, as well as other risk factors. The author first explains the basic anatomy and physiology of the esophagus, the lower esophageal sphincter (LES), and the stomach, then describes how surgical therapy can correct the underlying physical anomalies. The author then describes postoperative complications, followup data from research studies on this type of surgery, and areas of controversy. One sidebar describes the laparoscopic approach to this type of surgery. The author concludes by explaining the circumstances in which surgery would be an appropriate answer to the problems described.

Summary: This newsletter article reviews the differences between laparoscopy and open surgery for treating gallbladder disease. Unlike open gallbladder surgery, in which the surgeon makes an incision in the abdomen, the laparoscopic method requires only several tiny punctures in the belly to allow for the insertion of a small video camera and surgical instruments. The author reports results of a recent British study of 200 patients that showed that laparoscopic cholecystectomy (gallbladder removal) takes longer to do than mini-incision open surgery and offers no added benefit in recovery time, length of hospital stay, and time back to work. These results were in contrast to earlier evidence showing that people who undergo laparoscopy recover more quickly and with less pain and scarring than those treated with conventional open surgery. The author discusses the incidence of gallstones, the indications for cholecystectomy, rising rates of gallbladder removal, malpractice claims for bile duct injuries from laparoscopic cholecystectomy, and the differential diagnosis of gallbladder disease. The author stresses that the decision to have surgery is an individual one. People with infrequent gallstone attacks may be able to live with the prospect of having another down the road, while those whose episodes are more common or severe may find that laparoscopic cholecystectomy greatly improves the quality of their lives. 1 figure. •

Summary: Stress urinary incontinence (SUI) is the uncontrolled loss of urine caused when abdominal pressure overrides the closure mechanism of the bladder, allowing urine to leak out. Most women experiencing this type of leakage do so when coughing, sneezing, laughing, exercising, or lifting. One of the treatment options for SUI is surgical correction of this loss of support. This article describes this type of surgery, noting that a thorough evaluation needs to be done before surgery to consider non-surgical options and design the best surgical procedure if surgery is the treatment of choice. Topics include the goals of surgery, the surgical procedures that may be used, other support problems, what to expect after surgery, and the importance of making an informed choice about surgical options.

Surgery for Stress Incontinence Source: AUA News. 2(1): 16-17. January-February 1997. Contact: Available from AUA News. Williams and Wilkins, 351 West Camden Street, Baltimore, MD 21201-2436. Summary: This newsletter article reports on surgery for stress urinary incontinence (UI). All surgical approaches for stress incontinence have the common goal of restoring normal anatomic relationships; that is, to replace the bladder neck and proximal urethra into their appropriate position above the level of the pelvic floor muscle group. This positioning can be accomplished transvaginally or transabdominally; the approach is based on surgeon experience and preference, as well as on patient indications. The author reports on the surgical strategy to treat intrinsic sphincteric deficiency (ISD) or type III stress urinary incontinence. Generally, it is stated that there is an 85 percent cure rate of stress UI regardless of which procedure is performed. The author contends that the literature does not support this conclusion. The author also stresses that surgery only corrects one of the factors important for normal urinary control. Recurrence of UI
356 Surgery
with good anatomic support is not to be considered a surgical failure. The author concludes that more important than the choice of therapy is the identification of the proper patient for treatment. Correction of an anatomic abnormality by one of the many resuspension procedures will be inadequate for correction in those patients with ISD. Current urodynamic, radiographic, and endoscopic techniques must be used to select properly those patients who require augmentation of outlet function rather than an outlet stabilization (suspension) procedure. 1 figure. 3 references.

[email protected]. Website: www.spohnc.org. Summary: Over the past 30 years, surgical lasers have become a very useful tool in the treatment of cancer of the head and neck. This newsletter article describes the use of laser surgery for cancer of the larynx (voice box). Many surgeons have come to favor endoscopic excision over radiation therapy for early cancers on the vocal folds in order to avoid the disadvantages of radiation. The carbon dioxide laser was used in a large portion of the patients who were treated with endoscopic excision, which is an ambulatory surgery procedure. The authors note that high cure rates have been achieved treating early glottic (vocal cord) cancer with endoscopic excision, usually using the carbon dioxide laser. The authors caution that the decision as to when it is best to use, or not to use, a laser in the treatment of cancer of the larynx is complex. 8 references.

[email protected]. Website: www.spohnc.org. Summary: This article reviews the different types of surgery that may be used for cancer of the larynx (voice box). The author first briefly reviews the anatomy and function of the larynx. The author notes that most patients, when given the diagnosis of cancer of the larynx, assume that if they have surgery, it will mean loss of the voice box and loss of speech; this is not necessarily so. The author then describes the different approaches to surgery and to rehabilitation, including the ways that speech tone can be generated: with an electrical device that creates a tone (electrolarynx); with air expelled from the esophagus (esophageal speech); or with a one way valve that is surgically placed between the windpipe and the esophagus to allow air to be pushed from the lungs to the throat, making the throat vibrate and generating the tone to speak (voice prosthesis). The author then reviews the surgical approaches used to save the larynx, as alternatives to nonsurgical therapies such as radiation therapy alone or radiation therapy with chemotherapy. The author stresses that all patients who fail radiation therapy (whose cancers are not cured by radiation therapy) should be evaluated by a surgeon who regularly uses all of the organ preservation surgical techniques to determine if the patient is a candidate for one of them. 11 references.

[email protected]. Website: www.spohnc.org. Summary: This article, from a newsletter for people with oral or head and neck cancer, reviews the major advances in reconstructive surgery of the head and neck. The author notes that surgical treatment of tumors of the head and neck is similar to that of tumors elsewhere in the body, in that the goals of treatment are to remove the tumor in its entirety while preserving the form and function of the region. However, this may not be as easy to accomplish in the head and neck region as it is in other parts of the body. After a brief presentation of the historical perspective, the author's discussion revolves around four issues: the anatomic parts that are affected by the tumor and therefore require removal to obtain clear margins around the disease; the factors that exist that would lead to an impairment in wound healing; the best surgical approaches for tumor removal, leading to the least alteration in form and function; and the best method to reconstruct the missing anatomic parts to restore appearance as well as physiologic function.

CHAPTER 10. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for surgery. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a nonprofit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with surgery. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks, etc.). The

Researching Medications 367
Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/. PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee.
Researching Orphan Drugs Although the list of orphan drugs is revised on a daily basis, you can quickly research orphan drugs that might be applicable to surgery by using the database managed by the National Organization for Rare Disorders, Inc. (NORD), at http://www.rarediseases.org/. Scroll down the page, and on the left toolbar, click on “Orphan Drug Designation Database.” On this page (http://www.rarediseases.org/search/noddsearch.html), type “surgery” (or synonyms) into the search box, and click “Submit Query.” When you receive your results, note that not all of the drugs may be relevant, as some may have been withdrawn from orphan status. Write down or print out the name of each drug and the relevant contact information. From there, visit the Pharmacopeia Web site and type the name of each orphan drug into the search box at http://www.nlm.nih.gov/medlineplus/druginformation.html. You may need to contact the sponsor or NORD for further information. NORD conducts “early access programs for investigational new drugs (IND) under the Food and Drug Administration’s (FDA’s) approval ‘Treatment INDs’ programs which allow for a limited number of individuals to receive investigational drugs before FDA marketing approval.” If the orphan product about which you are seeking information is approved for

Recommendations for the Prevention of Human Immunodeficiency Virus (HIV) Transmission in the Practice of Orthopaedic Surgery Contact: American Academy of Orthopaedic Surgeons, 6300 N River Rd, Rosemont, IL, 60018-4262, (847) 823-7186. Summary: This report makes recommendations to prevent the transmission of the Human immunodeficiency virus (HIV) during surgical procedures. It says that orthopaedic surgeons face a particular risk because of their dealings with trauma cases, the sharpness of skeletal fragments, and the nature of their instruments. However, it also says surgeons have an obligation to provide high-quality care to all patients, including those with Acquired immunodeficiency syndrome (AIDS). The first section of the report deals with the possible risk that orthopaedic surgeons face of contracting HIV through occupational exposure. The second section provides scientific and epidemiologic data on HIV and AIDS, including modes of transmission, the risk from blood transfusions, the risk to health-care workers, universal precautions, and antibody tests. The third and final section outlines specific recommendations on universal precautions, including invasive procedures, use of blood, bone and soft-tissue allografts, responsibility toward patients, and testing of both patients and health-care workers.

Hepatitis B Virus Infection Without Immunological Markers After Open-Heart Surgery Source: Lancet. 345(8946): 355-357. February 11, 1995. Summary: Posttransfusion hepatitis is still an important problem, despite the screening of blood donors for hepatitis B virus (HBV) and hepatitis C virus infections. This article reports on a study in which the researchers assessed whether HBV DNA might be detected by PCR in prospectively collected serum samples of patients with unexplained posttransfusion hepatitis but no immunological HBV markers. They found HBV DNA in 4 (20 percent) of 20 patients with unexplained posttransfusion hepatitis and in 5 patients with mildly increased aminotransferases. The clinical course of these HBV infections was usually mild and self-limiting. The researchers conclude that low-titre, immunologically negative HBV infections do exist and might represent a significant cause of post-transfusion hepatitis.

Gastrointestinal Surgery for Severe Obesity Source: Bethesda, MD: National Institutes of Health. 1991. 22 p. Contact: Available from National Institutes of Health. Office of Medical Applications of Research, Building 1, Room 260, Bethesda, MD 20892. (301) 496-1144. Summary: The National Institutes of Health Consensus Development Conference on Gastrointestinal Surgery for Severe Obesity brought together surgeons, gastroenterologists, endocrinologists, psychiatrists, nutritionists, and other health care professionals as well as the public in March of 1991. The conference addressed the nonsurgical treatment options for severe obesity, the surgical treatments for severe obesity and the criteria for selection, the efficacy and risks of surgical treatments for severe obesity, and the need for future research on and epidemiological evaluation of these therapies. This brochure reprints the full text of the consensus panel's statement. Among their findings, the panel recommended that patients seeking therapy for severe obesity for the first time should be considered for treatment in a nonsurgical program with integrated components of a dietary regimen, appropriate exercise, and behavioral modification and support; gastric restrictive or bypass procedures could be considered for well-informed and motivated patients with acceptable operative risks; patients who are candidates for surgical procedures should be selected carefully after evaluation by a multidisciplinary team; the operation should be performed by a surgeon with substantial experience with the appropriate procedures and working in a clinical setting with adequate support for all aspects of management and assessment; and lifelong medical surveillance after surgical therapy is a necessity.

APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on surgery can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to surgery. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to surgery. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas.

Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on surgery. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/.

Summary: This full color patient education brochure uses a question and answer format to provide people who have spinal conditions with information on spinal fusion surgery. A surgeon may consider spinal fusion to treat a fractured vertebrae, correct certain types of spinal deformities such as scoliosis, eliminate pain from painful spinal motion, treat instability, and treat some cervical disc herniations. However, treatment of back or neck pain alone by spinal fusion is somewhat controversial because it is difficult to locate the source of pain in many patients. Surgical approaches and methods to fuse the spine all involve placement of a bone graft between the vertebrae. Fusion may or may not involve the use of hardware such as plates, screws, and cages. Regardless of whether or not hardware is used, bone or bone substitutes must be used to get the vertebrae to fuse together. Pain and recovery following spinal fusion are generally greater than with other types of spinal surgeries. Methods of postoperative pain control include oral pain medications, intravenous injections, and a patient controlled postoperative pain control pump. Return to normal activities is slower after spinal fusion because evidence of bone healing must be found before normal activities can be resumed. A brace is sometimes used for the early postoperative period. A postoperative rehabilitation that includes back strengthening exercises, a cardiovascular conditioning program, and a comprehensive program custom designed for the patient's work environment may be recommended. Spinal fusion is a good treatment for some spinal conditions, but it does not return the spine to normal.

Hip and Knee Replacement Surgery Source: Atlanta, GA: Arthritis Foundation. 2003. 20 p. Contact: Available from Arthritis Foundation. P.O. Box 7669, Atlanta, GA 30357-0669. (800) 283-7800. Website: www.arthritis.org. Summary: This brochure discusses joint replacement in patients with arthritis in their hips and knees. Hip and knee joints are replaced when pain in these joints has become so severe that the patient is unable to perform activities of daily living. Total joint replacement is performed when all other treatment methods have failed. The damaged bone or cartilage is removed and replaced with an artificial joint made up of polyethylene, metal and/or ceramic. Partial knee replacements are performed on patients with osteoarthritis on only one side of their knee. The three main types of knee and hip replacements are cemented, cementless, and hybrid. Cemented implants work best for older patients and patients with osteoporosis. Cementless implants last longer but require a longer recovery time. Hybrid implants are a combination of cemented and cementless components. The best way to find an orthopedic surgeon is to get a referral from a primary care physician or rheumatologist. A list of questions for interviewing potential surgeons is included. Patients should prepare for surgery by choosing anesthesia, losing weight if overweight, exercising to improve endurance, enlisting family members for help after the surgery, considering blood donation, and preparing the home for post-surgery recovery. The surgical procedure for hip and knee

Summary: This fact sheet provides patients with information about dermal electroshave excision, a technique used to remove skin tumors and skin growths. This technique allows the tumor or growth to be removed without penetrating the skin. Shave excision is less expensive and results in less noticeable scarring and fewer infections than full thickness skin excision. Local anesthesia is used. After excision the tumor or growth is sent to a lab for analysis. Any scarring caused by the procedure will eventually fade. After the surgery, an antibiotic cream and a solution to stop bleeding will be applied to the wound. Nonprescription pain relievers may be taken. If the wound becomes infected or if the scar becomes hard the patient should contact the doctor. •

Plastic Surgery Considered Source: Sharon, MA: PXE International. 2001. 4 p. Contact: Available from PXE International. 23 Mountain Street, Sharon, MA 02067. (781) 784-3817. Fax (781) 784-6672. E-mail:
[email protected]. Website: www.pxe.org. PRICE: Single copy free. Summary: This fact sheet, which is based on a presentation given at the International Centennial Meeting on Pseudoxanthoma Elasticum (PXE), provides people who have PXE with information on plastic surgery. Wrinkles, folds, and looseness of the skin may result from PXE, and these can be removed with plastic surgery. However, the cobblestone appearance of the skin cannot be changed by surgery. One surgical technique that can be used in people affected by PXE is a procedure called direct excision. The folds and loose skin are smoothed out by pulling the skin in one direction, and the excess skin is cut away. However, this procedure may leave an obvious scar. Other procedures that can be used to improve the appearance of folds and loose skin include a face lift, a neck lift, or tightening of the skin of the breasts or abdomen. Anyone considering one of these procedures should find out where the incisions will be and understand that permanent scarring could occur. A person who is considering surgery should have a thorough preoperative cardiac workup and an evaluation of all other systems. Postoperative complications include scarring, calcium extrusion, infections, reaction to anesthesia, and risk of hematoma. One difficulty PXE patients deal with in deciding whether to undergo plastic surgery is that insurance coverage may be initially denied for some patients. The key to the decision is usually based on the definition of plastic surgery as either reconstructive surgery or cosmetic surgery. PXE is a congenital condition, so corrective procedures should be defined as reconstructive surgery and, thus, covered by insurance.

The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources
A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

402 Surgery
Background: AirLifeLine is a national nonprofit organization of private pilots who donate their time, skills, aircraft, and fuel to fly medical missions. Founded in 1978, the program was initially established to provide efficient transportation of time-critical medical cargo. In 1984, the organization's services were expanded to include ambulatory patients who require life-sustaining treatments, such as surgery, chemotherapy, radiation, or medical care, at medical facilities far from home and who cannot afford the cost of travel. The program, which initially included 25 interested pilots in California, has grown to include over 900 pilots nationwide. The program's services are provided at no cost to patients or referring agencies. AirLifeLine provides flights for patients who fulfill certain criteria (e.g., demonstrated medical and financial needs, etc.) and for an accompanying support person or persons, such as the parents of an ill child. The organization does not limit its services to a specific age group of patients nor to specific medical diagnoses. In addition to providing flights for patients who need to travel to medical treatment centers, AirLifeLine also offers flights to help fulfill the wishes of terminally ill patients. This type of request must come for an organization, agency, or hospital that is aware of the patient's situation. To a limited degree, the program also flies time-critical cargo, such as blood or donor organs for transplants and other types of surgery. AirLifeLine receives referrals from health care and hospital social workers, discharge planners, and voluntary organizations. In addition, patients and family members may directly contact the organization for assistance. •

SURGERY DICTIONARY The definitions below are derived from official public sources, including the National Institutes of Health [NIH] and the European Union [EU]. 3-dimensional: 3-D. A graphic display of depth, width, and height. Three-dimensional radiation therapy uses computers to create a 3-dimensional picture of the tumor. This allows doctors to give the highest possible dose of radiation to the tumor, while sparing the normal tissue as much as possible. [NIH] Abdomen: That portion of the body that lies between the thorax and the pelvis. [NIH] Abdominal: Having to do with the abdomen, which is the part of the body between the chest and the hips that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs. [NIH] Abdominal Pain: Sensation of discomfort, distress, or agony in the abdominal region. [NIH] Abducens: A striated, extrinsic muscle of the eyeball that originates from the annulus of Zinn.

Damage to the nerve or its nucleus disrupts horizontal eye movement control. [NIH] Abducens Nerve Diseases: Diseases of the sixth cranial (abducens) nerve or its nucleus in the pons. The nerve may be injured along its course in the pons, intracranially as it travels along the base of the brain, in the cavernous sinus, or at the level of superior orbital fissure or orbit. Dysfunction of the nerve causes lateral rectus muscle weakness, resulting in horizontal diplopia that is maximal when the affected eye is abducted and esotropia. Common conditions associated with nerve injury include intracranial hypertension; craniocerebral trauma; ischemia; and infratentorial neoplasms.

Complement activation occurs by two different sequences, the classic and alternative pathways. The proteins of the classic pathway are termed 'components of complement' and are designated by the symbols C1 through C9. C1 is a calcium-dependent complex of three distinct proteins C1q, C1r and C1s. The proteins of the alternative pathway (collectively referred to as the properdin system) and complement regulatory proteins are known by semisystematic or trivial names. Fragments resulting from proteolytic cleavage of complement proteins are designated with lower-case letter suffixes, e.g., C3a. Inactivated fragments may be designated with the suffix 'i', e.g. C3bi. Activated components or complexes with biological activity are designated by a bar over the symbol e.g. C1 or C4b,2a. The classic pathway is activated by the binding of C1 to classic pathway activators, primarily antigen-antibody complexes containing IgM, IgG1, IgG3; C1q binds to a single IgM molecule or two adjacent IgG molecules. The alternative pathway can be activated by IgA immune complexes and also by nonimmunologic materials including bacterial endotoxins, microbial polysaccharides, and cell walls. Activation of the classic pathway triggers an enzymatic cascade involving C1, C4, C2 and C3; activation of the alternative pathway triggers a cascade involving C3 and factors B, D and P. Both result in the cleavage of C5 and the formation of the membrane attack complex. Complement activation also results in the formation of many biologically active complement fragments that act as anaphylatoxins, opsonins, or chemotactic factors.
