High-resolution endoscopy and narrowband imaging have revolutionized the field. Edited by a gastroenterologist with a reputation for delivering outstanding material, this new edition of an award-winning atlas provides you with an outstanding collection of images, videos, and expert diagnostic guidance to enhance your decision making. To accelerate your learning, Dr. Cohen offers more than 2000 endoscopic images, emphasizing conditions for which NBI is particularly useful – such as finding dysplasia in Barrett's mucosa, and diagnosing adenomatous colon polyps – and providing exceptional preparation for the future of endoscopy practice, with a broad new look at normal and abnormal findings throughout the GI tract. The book is divided into three main parts: The accompanying website features more than 85 video clips containing over 3 hours of annotated video, to give you a complete sense of how HRE and NBI work and look in real time, including during therapeutic procedures. All of the over 1000 new images appear in much brighter color, reflecting the advance in scope technology since the first edition. New chapters have been added to present the data supporting increased use of NBI in optical diagnosis and in the context of therapeutic procedures. For the first time, brilliant images of the bile duct and pancreas are included as the imaging revolution has expanded to reach these new locations. This spectacular new imaging modality promises to enhance endoscopic decision making in real time, facilitate therapeutic maneuvers, make tissue sampling more precise, and make resection of mucosal neoplasia more complete. Expertly guiding you through the latest advances, this book facilitates your mastery of the field, and provides an up-to-date reference for gastroenterologists and endoscopists to improve their practice.
