Metastases determine malignancy. The main attention so far has been focused upon organ metastases. The molecular mechanisms thereof, while far from being totally elucidated, are increasingly well understood. Modern diagnostic tools now enable detection and precise localization of small lesions. In contrast, our knowl edge and diagnostic capabilities regarding metastatic spread to the'lymphatic system are rather limited. However, there have re cently been a number of interesting advances. It is the aim of this volume to submit these developments to detailed analysis. The therapeutic relevance of enhanced sensitivity in detection of lymph node metastases has to be considered in the light of in creased morbidity versus eventual prognostic improvements by modification of therapy. An interesting concept which might im prove diagnostic accuracy while reducing operative morbidity is the "sentinel node" technique. Surgical standards are lacking, however, and many fundamental questions pertaining to precise lymphatic mapping remain unanswered. Whether the sentinel node concept is of general relevance or whether it is applicable in only a few organs remains to be determined. This book offers intensive discussion of the concept from methodological and tu mor biological viewpoints. World-renowned experts with long term involvement in related basic and clinical research provide the reader with a broad survey of actual knowledge together with a critical appraisal of recent and future developments. We sincerely hope this book succeeds in providing an outlook as a reference for all clinicians on future prospects and serving and researchers in this extremely important field.

General surgery consists ofa main corpus of propaedeutic elements and clinical problems, which has been modified over the years by the separate development of numerous sub-specialistic branches. Although a common basis on the physiopathology of surgical trauma and post operative complications persists, as a result of general knowledge of surgical diseases, there is no doubt that in the spheres of doctrine and application, both research and clinical medicine have distinguished themselves autonomously in many surgical fields (orthopedics, neurosurgery, cardiovascular surgery, thoracic surgery, urology, etc.). It is therefore difficult to define the present configuration ofgeneral surgery, but without question abdominal surgery occupies a position of pre-eminent importance within the general framework. We are dealing, in fact, with pathological pictures which occur in a section ofthe body ofvast proportions, in which structures, organs, and morphologically complex spaces are arranged to carry out important functions. They are, therefore, subject to considerably complex pathological alterations, such as to establish an interesting field of diagnostic discussion and an exciting training-ground for surgical activity. It can be affirmed that the diagnosis and cures ofabdominal surgical diseases constitute a test ofthe surgeon's experience. Diagnosis is often entrusted to a differential process, the results ofwhich may be confirmed today by complementary diagnostics. This, however, must be guided by predominating clinical considerations, the exaggerated use of diagnostic techniques, detached from clinical examination, being the cause of very serious errors, which can mislead decision making and human contact, which is the basis ofcorrect medical practice.

Since RUTHERFORD MORISON left us with the concept of the Omentum being the 'abdominal policeman', clinicians have tacitly assumed that they know sufficient about the structure and function of this organ. However interest in the omentum and its relationship to clinical surgery has recently been develop ing. This book examines all aspects with special reference to surgery and should provide a welcome impetus in research and clinical practice. The editors and contributors have produced a book which is comprehensive and well illustrated and contains detailed refer ences to the important original sources - so essential in a work of this nature. It is written for those who wish to share the delight of acquiring knowledge - even about a comparatively humble organ - as well as for practical surgeons. Both will find ample information to arouse their interest and expand their surgical horizons in exciting ways of which they will almost certainly not have dreamt. I welcome a book of this calibre on a subject which deserves our increasing interest. I delight in the fact that it is dedicated to my friend and colleague MARTIN ALLGOWER.

Apart from the articles on history and nursing, the con- ditions discussed include Mediastinal Masses in childhood seen from a Pathologist's point of view, Intrapulmonary se- questration, lymphangiomata involving the neck as well as thorax, unusual forms of Diaphragmatic Hernia and Congenital Heart Disease. Such a volume would hardly be complete with- out some references to Oesophageal Atresia and one article discusses The Influence Of Anatomy And Physiology On The Ma- nagement Of Oesophageal Atresia.

Pancreatic Disease: Basic Science and Clinical Management summarises the state of the art in basic science and clinical management of pancreatic disease. This book provides a clear and up-to-date review of the advancing areas in clinical pancreatology and clinical research related to the pancreas. Written by leading experts in the field, this comprehensive review directs the interested reader towards important and current published source material. Covering all aspects of pancreatic disease, contributions are included from pancreatic surgeons and medical pancreatologists on pancreatic cancer, acute pancreatitis and chronic pancreatitis. Special features include a systematic review of the evidence for the use of gemcitabine in pancreatic cancer prepared for the National Institute of Clinical Excellence (NICE), the UK body charged with evaluating new drug treatment. Gemcitabine has FDA approval. There are several contributions dealing with the management of pancreatic neuroendocrine tumours. This book will be useful to gastroenterologists, internists and surgeons, and specialist clinicians with an interest in pancreatic disease. Trainees in medical and surgical pancreatology will find it a companion to supplement standard textbooks.

This book represents the proceedings from a conference that took place in Dallas in the spring of 1999 which was entitled "Pediatric Gender Assignment - A Critical Reappraisal". Some participants rightfully argued that the conference really focused on the issue of pediatric gender assignment, and that reassignment was not applied in most cases. Their comments were reflected in the title of this monograph. This multidisciplinary meeting was sponsored by a conference grant from the National Institutes of Health, and a broad inquiry into this complex topic took place from many points of view. Basic scientists offered insight into mechanisms of sexual differentiation of the gonads, physical phenotype and imprinting of the central nervous system. Endocrinologists reviewed their experience in diagnosis and management, surgeons described traditional as well as innovative approaches, and there was strong representation from the ethical and behavioral sciences. In putting together such a panel, it was essential that we identify a cast of speakers who could address their viewpoints with strong convictions, and yet not let their passions render the meeting counter productive. We were not disappointed. While many differing points of view were firmly expressed by the panelists and audience, all viewpoints were accorded the respect they deserved. The concept behind the meeting and this book really originated in 1997 shortly after Diamond and Sigmundson published their long term follow up study of the John/Joan case.

This book provides a concise summary across all aspects of endocrine surgery, covering the major endocrine organs and discussing aspects of surgical care. It comprises five sections covering the major endocrine organs/systems, each with a specialist section editor. Within each section there are a number of brief (2-3 page) chapters, written in a combination of prose and bullet points, a format that is conducive to both detailed reading and quicker, "dipping in", review. Each chapter contains a "Pearls and Pitfalls" summary box. The text takes into account the latest evidence and current expert opinion from an internationally renowned list of authors.

The advent in the 1960s of the unique and exciting new form of energy called laser brought to medicine a marvelous tool that could accomplish new treatments of previously untreatable disorders as well as improved treat ment of mundane problems. This brilliant form of light energy is many times more powerful than the energy of the sun yet can be focused microscopically to spot sizes as small as 30 microns. Lasers can be directed into seemingly inaccessible areas by mirrors or fiberoptic cables or can be directly applied into sensitive areas such as the retina without damage to intervening structures. There has been a rapid proliferation in the use of lasers in all surgical specialties. Starting with bold ideas and experiments of "thought leaders" in each specialty, the application of lasers has evolved into commonplace usage. Beginning with the era when laser presentations and publications were an oddity, now nearly all specialty areas have whole sections of meetings or journals devoted exclusively to laser usage. Laser specialty societies within a specialty have developed and residency training programs routinely instruct trainees in laser techniques. Basic science and clinical experimentation has supported laser knowledge. Laser usage has also become international. Newer wavelengths and accessories have added to the armamentarium of laser usage. Despite the rapid growth in laser interest, no single source exists to instruct the many new laser users in proper, safe, and effective use of this new modality."

It is estimated that the functionally significant body of knowledge for a given medical specialty changes radically every 8 years. New specialties and "sub-specialization" are occurring at approximately an equal rate. Historically, established journals have not been able either to absorb this increase in publishable material or to extend their readership to the new specialists. International and national meetings, symposia and seminars, workshops, and newsletters suc cessfully bring to the attention of physicians within developing spe cialties what is occurring, but generally only in demonstration form without providing historical perspective, pathoanatomical corre lates, or extensive discussion. Page and time limitations oblige the authors to present only the essence of their material. Pediatric neurosurgery is an example of a specialty that has de veloped during the past 15 years. Over this period neurosurgeons have obtained special training in pediatric neurosurgery and then dedicated themselves primarily to its practice. Centers, Chairs, and educational programs have been established as groups of neuro surgeons in different countries throughout the world organized themselves respectively into national and international societies for pediatric neurosurgery. These events were both preceded and fol lowed by specialized courses, national and international journals, and ever-increasing clinical and investigative studies into all aspects of surgically treatable diseases of the child's nervous system.

This must-have manual for surgical residents and vascular surgery trainees is copiously illustrated with more than 250 original line drawings. The author presents in a step-by-step fashion the techniques for all common vascular reconstructions, basics of exposure and access, as well as invaluable technical pearls and tips. The text provides the surgical trainee with the opportunity to review and practice the necessary vascular reconstructions before entering the operating room. The illustrations and clear instructions make this a manual that is referred to again and again throughout the surgical residency.

Gastrointestinal Surgery: Pathophysiology and Management is an invaluable reference text for surgeons and surgical trainees. Written entirely by Dr. Haile T. Debas, Dean of School of Medicine and former Professor and Chairman, Department of Surgery, at the University of California, San Francisco, this book provides the unified approach only found in a single-authored text. Based on the three pillars of understanding particular disease processes -- fundamental anatomy and physiology, pathopysiology, and clinical correlations -- surgical treatment of GI disease is presented as the means to correct abnormal physiology and restore health. Using an integrated approach of basic science and clinical practice, Dr. Debas allows the student of surgery to gain a solid understanding of disease processes that minimizes the need for rote memorization. Thirteen lavishly illustrated chapters cover the GI system as well as gastrointestinal peptides and peptide-secreting tumors, abdominal trauma, the abdominal wall, surgery for morbid obesity, the liver, spleen, retroperitoneum, and perioperative care. Dozens of summary tables throughout each chapter condense "essentials" for quick reference. Comprehensive discussions of clinical disorders review the surgical treatment options. With 400 illustrations and tables, including hundreds of anatomical line drawings commissioned exclusively for this textbook, Gastrointestinal Surgery provides a clinical and therapeutic approach to surgical diseases which will prove invaluable to the surgical trainee and the practitioner preparing for recertification.

Alessandro Condivilla of Bologna first attempted a resection of the head of the pan creas in 1898, but several decades of further trial-and-error attempts ensued before the prototype procedure of pancreatoduodenectomy (PD) was established by Whipple in 1935. In the half-century following that landmark, refinements of surgical technique, including pancreatico-and bilio-entero anastomosis as well as develop ment of new technology to support perioperative management and patient care have contributed to the decrease in mortality and morbidity rates for obstructive jaundice and pancreatic fistula. The improvement in mortality and morbidity rates associated with PD has led to an increase in the number of patients undergoing the procedure and in the number of institutions performing it. Indications for PD have also been expanded. In the early years after PD was established as a viable procedure, periampullary carcinoma was the most common indication; now PD is indicated for a number of benign and malignant diseases. Some surgeons believe that PD is the procedure of choice for certain types of chronic pancreatitis, pancreatico-biliary maljunction, and pancreatic and duodenal trauma. Other surgeons have reported the necessity of PD for lymph node dissection of gallbladder carcinoma. Consequently, the basic procedure has been greatly modi fied to accommodate the specific conditions of each disease. For patients with malig nancy, extended procedures have been developed to improve the curative resection rate and ensure complete lymph node dissection."

Professor George Fegan is a world authority on the use of sclerotherapy for the treatment of varicose veins. His technique for injecting varicose veins is regarded by many to be the best method for achieving success with sclerotherapy. Professor Fegan first published his method in 1963. This book is an update to his previous work and describes his method step by step as well as relevant information on the anatomy, physiology, pathology and investigations of varicose veins. Sclerotherapy is finding its place as an effective weapon in the phlebologist's armamentarium, and its indications are becoming clearer. All involved in the care of patients with venous disease will find this an invaluable read.

Both the investigation and treatment of cancer of the oesophagus are comprehensively presented in Management of Oesophageal Carcinoma. This information is otherwise not easily available in one source. The chapters are written by experts in the fields of anatomy, cancer research, radiology, and thoracic surgery and give up-to-date information on this difficult disease. All aspects are covered: anatomy, epidemiology, endoscopic and radiologic diagnosis, pathology, surgical treatment, radiotherapy, palliative and laser therapy, and the management of complications. Surgeons will be especially interested in the discussion of the recent technique of oesophagectomy without formal thoracotomy, and the use of stapling devices. This complete reference is ideal for all clinics and medical centers specializing in thoracic surgery or treatment of oesophageal carcinoma.

Endoscopic surgery in children is a rapidly expanding field in pediatric surgery. This book represents the state of the art, and explains why endoscopic surgery in children is so important. General aspects are discussed and detailed information is provided on many specific operations both in the chest as well as in the abdomen, including endoscopic treatment of throracic scoliosis, of urogenital conditions, and of neurosurgical conditions. Application of endoscopic techniques in oncology is discussed as well. A special chapter deals with complications.

In an attempt to attain the best possible delimitation of all the problems posed today by benign diseases of the esophagus, 181 authors each agreed to answer one or more of 210 questions that had been drawn up on the subject. These questions, each one deliberately limited and difficult, mostly concerned reflux esophagitis: its natural history, the means of its diagnosis, all existing treatments, and its eventual degeneration. The authors approached are today's most reputed specialists in the fields of epidemiology, gastroenterology, endoscopy, pathology, and surgery of esophageal diseases. The authors were all assigned one or more questions in their own field, none of which was simple: all did their best to synthesize in their replies their own experience on the precise point under review and included all the most useful bibliographical references on the topic. The book is thus the result of an original, individual approach to try to pinpoint the heart of a problem. The 210 answers succeed one another in logical progression according to the different diagnostic and therapeutic stages, specifying, at each step, the degree of precision sought. Consequently, the reader has at his disposal an exceptional synthesis of facts and concepts. Opening the book at random he will find at once the detail he is looking for, the professional opinion he is lacking, or the development of a question he had perhaps not yet asked himself.

When one deals with cancer, the hepatobiliary malignancies present a chal lenge to the oncologists that can be characterized as a series of unsolved clinical and biological dilemmas. Liver metastases from colorectal and other gastrointestinal malignancies, hepatocellular carcinoma, cholangiocar cinoma, and gall bladder cancer present an array of problems but have two features in common. These are high morbidity and mortality with an overall poor result from treatment. Why is it that hepatobiliary cancer carries with it such a dismal prognosis? First of all, these diseases present, for the most part, in an advanced state. To this point in time the oncologist has had no help from early diagnosis or screening. Only the occasional patient followed by ultrasound or a tumor marker has the disease diagnosed in an asymptomatic state. By the time these diseases become symptomatic, curative treatment options have usually disappeared. Evolution has placed the liver in a protected position in order to avoid injury to the soft parenchyma. As with many other internal organs, the nerve supply is extremely limited. These two anatomic features result in a great lack of early warning signs of cancer.

Recent developments have favourably and extensively altered general surgical practice. As editor I have happily been able to select certain topics of new and major interest for detailed discussion and have thus had the opportunity to collect these authoritative submissions within the covers of one text. The range of topics is broad. Endoscopy has changed the nature of both investigation and treatment of much gastrointestinal disease and the therapeutic uses of endoscopy continue to grow. That sophisticated new tool of the radiologist, computerized axial tomography, has revolu tionized the diagnosis of intra-abdominal disease, very often permitting precise localization of hitherto occult disease, and, as might be expect ed, it has become helpful in determining both the nature and extent of surgical and other therapy. Although an invasive procedure, intra abdominal angiography has similarly come of age as a means of localiz ing gastrointestinal haemorrhage and controlling such bleeding. Unfortunately, intra-abdominal malignancy continues to be a major source of concern to the general surgeon and the discovery that such tumours are associated with unusual markers, termed oncofetal anti gens, suggests that early diagnosis and early detection of recurrence may yet be feasible. Adjuvant or post-surgical therapy is an exciting de velopment in terms of prolonging the disease-free interval in women with breast cancer limited to regional lymph nodes. Equally efficacious therapy is not yet available for patients with gastrointestinal cancer, highlighting the need for more specific drugs and drug combinations."

Although the number of published papers on traumatic hip disloca tion in childhood is large, our actual current knowledge on this inju ry in this age group is still full of obscure points and unsolved prob lems. Luxation of the hip of traumatic origin in children is infrequent, and the small number of cases reported by authors and institutions, as well as the usually short follow-up in many cases, are responsible for the many doubts and questions, especially related to complications and outcome following the injury. Consequently the treatment, especially the postreduction management, has not been adequately defined. Dr. Antonio Barquet has made the great effort to analyze the ex perience gained from 38 cases in Uruguay and to review more than 500 references related to the subject, covering more than 1400 cases. He began to study this topic in 1976. It was the subject of his postgraduate monograph in 1979, which was followed by a statisti cal analysis of the major complication, i. e., avascular necrosis of the proximal femoral extremity, which was presented as his doctoral thesis in 1981. In addition, he has published numerous papers deal ing with several aspects of traumatic hip dislocation in children."

Inflammatory dieseases of the pancreas occur with increasing incidence in western industrialized countries. This volume deals with all aspects of CHRONIC PANCREATITIS including epidemiology, etiology, morphology and pathophysiology, dia- gnostic imaging as well as conservative and operative treat- ment. Very recent data based on experimental and clinical research projects are presented. The contributions have all been written by a team of internationally well recognized authorities in the various fields involved. Topics of parti- cular interest include feed-back regulation, new aspects of conservative and interventional treatment as well as modern surgical approaches including organ-preserving procedures.

Material for this book was gathered in the early 1980's in Manchester, where a higher incidence than usual of complications in the gastro-intestinal and urinary tract was observed. Part I describes the principles and methods of radiotherapy for pelvic tumours, pathological features and radiological analysis of bowel and urinary tract changes. Parts II and III are devoted to clinical assessment and management, where the need for a multi-diciplinary approach is emphasized.

This volume provides in a conveniently accessible package a comprehensive collection of accurate and timely information on the management of patients with diarrhea, both in pediatric age and in the adult. As medical knowledge has recently expanded in this area, this volume is full of new practical, clinically useful material for the busy clinician. Illustrations are emphasized to permit rapid acquisition of practical information that is not readily available in the major texts. Each chapter is concise, concentrating on "clinical pearls," and new advances in diagnostic and therapeutic technology. Each chapter discusses the relative costs of diagnostic and therapeutic options to permit financial considerations to be taken into account in the decision making process. Additional unique features include, summaries of key points, recommendations, and indications for requesting GI subspecialty consultation. Providing a comprehensive but practical overview of the issues surrounding the diarrheal diseases, this volume will prove of great value and utility to gastroenterologists, surgeons, internists, primary care physicians.

This book reviews the most recent developments in the patho- physiology and therapy of ventilatory failure. It contains contributions by twenty-five internationally recognized aut- horities on respiratory muscle function and investigators actively contributing to our knowledge of the cause, diagno- sis and therapy of ventilatory failure. Of particular inter- estare the descriptions of new modalities of partial and complete ventilatory assistance as well as new knowledge re- garding ventilatory control and fatigue during stressful breathing. The reader will find here a state-of-the-art re- view of the latest research and practical applications in this most critical area of intensive care medicine.
