This 6th volume of OESO has the advantage to address a topic which is at the forefront of concern for all those involved with disease of the upper digestive tract: an entity inserted in the epidemiological sequence of GERD, a benign affection among the most widespread in the world, Barrett's esophagus, has become today a problem of Public Health. Its recognised propensity to degenerate has, in fact, made it one of the benign lesions of the upper digestive tract which legitimately arouses the convergent interest of clinicians, as well as those devoted to fundamental research. Large scale epidemiological studies, the development of even sharper means for early detection of the precursory signs of its degeneration, the extreme diversity of the treatments available today, all lend new perspectives to the different centres of interest of this book.

This book is the 5th in an exceptional series which, in a most uncommon way, constitutes an original encyclopaedia of esophagology. It is devoted to a single subject: the esophagogastric junction. These few centimetres are dissected into 420 questions which call on all the disciplines involved by its physiology, its diverse diseases and their various treatments. 450 answers, provided by the most renowned experts, each one shedding light on one small, but essential, fragment of the subject. The book offers: A succesion of syntheses; A profusion of targeted bibliographical references; An access, now made easy, to highly elaborated knowledge; A precious volume for researchers, specialists, departments heads, general practitioners and students.
