Book excerpt: Endoscopy is the principal tool for the investigation of most disorders of the gastrointestinal tract. All practicing gastroenterologists must be able to perform the technique for diagnostic and therapeutic purposes. Successful endoscopy relies upon a grasp of what to do and how to do it (details of which are also found in books like Cotton and Williams) along with the ability to recognize abnormalities and diagnose disease. This book provides a very large collection of high quality images of normal and abnormal endoscopic appearances. Parallel pathological photomicrographs, together with a detailed running text, offer an approach not previously attempted. There are major chapters on the upper and lower gastrointestinal tract and on endoscopic retrograde cholangiopancreatography (ERCP). In addition there is a chapter on the rapidly developing field of enteroscopy. The contribution on endoscopic ultrasonography (EUS) will be of special interest to gastroenterologists and radiologists. There is also a chapter on "Getting the most out of your pathologist," explaining in some detail the pathologist's potential contributions. All chapters, as appropriate, include sections on technique and on therapeutic aspects of endoscopy. A special feature of Atlas of Gastrointestinal Endoscopy and Related Pathology is the extensive use of clear explanatory images: many of the endoscopic and radiological, and all the pathological and endosonographic figures are accompanied by annotated black-and-white corresponding figures. developed and expanded from the highly successful first edition, published in 1986 over 1900 figures over 1200 high quality endoscopic images parallel pathological photomicrographs diagnostic and therapeutic aspects of endoscopy includes the developing fields of enteroscopy and endoscopic ultrasonography full range of annotated explanatory images
