Foreword
Herniology, during the latter part of the twentieth century, had become transformed by the realization that most abdominal defects in the adult are not predetermined by anatomic anomalies. Rather, they relate to connective tissue damage brought about by abnormal collagen metabolism, secondary to extended longevity, cigarette smoking, or impaired genetic expression. Surgeons now recognize that sutured repairs under tension are liable to give way sooner or later. Fortunately, bridging with prosthetic mesh has repeatedly been shown to be well tolerated and successful when the interposition is firmly anchored. The introduction of laparoscopic placement has led to the competitive development of minimally invasive open techniques which, by reducing postoperative pain, hasten recovery.
The herniologist has emerged as a specialist, supported by a dedicated staff and clinic facilities, with a professional society and journal. Two of the heroes who, with their gold standard, led the way were the Shouldices, father and son. Therefore, it is fitting that this, the first new text of the third millenium, is edited by one of their colleagues. Robert Bendavid took a sabbatical year to write this book, with the help of his peers from around the world. Although educated in Canada, he was born overseas, and is multilingual. This skill has helped him edit the many foreign contributions in the light of his own enormous clinical experience. Robert, despite his promotion of the "Modern Bassini," has already put together an internationally recognized text on prostheses and abdominal wall hernias. He is well known for other original contributions-fletching and umbrella prostheses for groin defects, parapubic herniation, dysejaculation after hernia surgery, nomenclature, and a new understanding of the transversalis fascia. He has been a mainstay at international conferences on herniae during the past 15 years and has contributed 25 chapters to the textbooks of other editors.
The text itself, as is expected from such a leading scholar in the field, encompasses all the new information that has so recently become available. It begins with history, anatomy, epidemiology, and pathology. Extensive documentation of new biomaterials is followed by adjuncts to surgery, techniques of repair, plastic surgery, emergencies, and pediatrics. The female hernia patient is followed by the elderly, incidental pathology, sports injuries, and ventral defects. Finally, complications are dealt with, along with unusual herniae and medicolegal aspects.
It is a wonderfully fresh product that will serve as a point of reference for years to come. Dr. Bendavid and his co-editors have taken much time and trouble to provide us with a statement of what is known around the world today regarding herniology. Hopefully, this gift will enable us to better serve humanity.

Preface
It gives me particular pleasure to present the compilation Abdominal Wall Hernias: Principles and Management. One would not expect anything of less substance and quality from a textbook edited by Robert Bendavid, at the fateful start of the third millennium. Since Ephraim Chambers's and Denis Diderot's encyclopedic works, compilations such as this call for the collaboration of many experts, whose participation is obtained by virtue of the editor's own noteworthiness, unremitting work, and expertise in the subject. Is not every editor compelled to do better than his rivals in a strongly competitive field? This has been done-in the opinion of the most exacting among them.
The coauthors have reconsidered all the accepted classics in the light of more recent additions, in accordance with the editor's plan. The necessary chapters on fundamentals begin with the historical evolution of some of the main themes of surgery, as seen by surgeons themselves. Then, by way of update, comes the discussion of the many techniques commonly used in surgery of the abdominal wall, some already established, others-more recent-still in the process of being evaluated. Prostheses have a significant legitimate place, for they have experienced a remarkable upsurge and are used not only in recurrent hernias and burst abdomens, but also very considerably in primary treatment. Laparoscopic surgery of hernias-a seductive product of high technology-was another item to be tackled with particular attention among the methods being currently evaluated.
Thus, should readers wish to review a standard technique or one of its details, they will find it, more often than not, described by its inventor in this book. Should they be confronted by particular cases of rare hernias or exceptional circumstances, surgeons will be able to find exhaustive and up-twate information on these less familiar problems.
Certain matters rarely approached in detail have also been notably considered, such as abdominal wall surgery for patients with ascites, for athletes, the obese, women, the elderly, even for the futuristic surgeon-the intellectual disciple of Jules Verne-technologies yet to be invented, in which robots will perhaps make their appearance, technologies to be welcomed cautiously and on the condition that they bring true benefit to the patient and to society.
This book is a successful achievement, a tribute to the vitality of the surgeon of the abdominal wall. Remarkably illustrated, and with unvarying precision throughout, the work serves well its double purpose: to help readers to acquire fundamental, indispensable principles for up-twate understanding of abdominal wall pathology and to enhance their ability to make good choices of tactics or techniques, whatever the situation. This is the best one can ask for. Everyone knows that a consensus is unlikely, at present or in the near future, on the problem of the treatment of hernias. This question cannot be resolved solely by the contribution of scientific proofs, because it has "sociological" elements derived from the diversity of the many people concerned (the surgeons and their patients) and from the polymorphism of the lesions.
One can promise that Abdominal Wall Hernias: Principles and Management will fulfill the ethical obligation to further the teaching of abdominal wall surgery and the control of its quality. This remains essential to this day. The 1998 Inquiry of the National Union of the Medical Press and Health Professionals in France revealed that written documents are the primary source of information in continued medical education, ahead of conferences and meetings.

A book like this one must therefore have the support of many readers, as indeed one must hope it shall. But then, a simple glance at the table of contents is enough to disclose the difference between this and other comparable books, a difference in favor of the present work, which must take its place within reach of every surgeon's hand.
These few words are thus no more than a deliberately brief preface to the feasts prepared for the satisfaction of the reader.

Preface
Introduction
As we begin a new millennium, it seems fitting that a publication on hernias should meld the acquired knowledge and wisdom on the subject to constitute a state-of-the-science address-a century-ending statement before starting a new surgical period. This much has been attempted.
The versatility and speed of today's communications have brought more than 120 surgeons from 16 countries into a futuristic "surgical village" dotted with satellite dishes and antennas. The abundance of scientific information has been difficult to contain, but an effort has been made to include all current concepts, theories, practices, operations, prostheses, and even gadgets: so much so that inclusion should not be construed as a recommendation, which brings to mind a quote from Sir Maximillian Beerbohm, "It distresses me, this failure to keep pace with the leaders of thought, as they pass into oblivion!"
Foremost in my thoughts was an attempt to remain above controversy, to avoid bias, and to allow a generous exposure to all participants. To that end, I have to apologize for the elimination of certain chapters when authors were too opinionated too early, but also unshakeable in their attitude and presentation. The existence of an European Hernia Society and now the American Hernia Society has made it imperative that both sides of the Atlantic be given an even role in the elucidation of the hernia diathesis. This I feel was fairly accomplished.
This book was made possible thanks to the generosity of each contributor who shared his time and knowledge. I know also that for some it meant a sacrifice. For that, I am grateful, and many readers will express the same feeling. My hope is that the result will meet with their warm approval.
