Professors Wallace, Fockens, and Sung have recently published their third edition textbook in gastrointestinal endoscopy entitled, Gastroenterological Endoscopy. In collaboration with Thieme Publishers, the editors have expanded upon the two previous editions published by the founding editors, Professors Classen, Tytgat, and Lightdale. For those unfamiliar with this book, it is unlike any other in the field of endoscopy. This enormously comprehensive text (with multiple videos accompanying several of the chapters) clearly achieves its goal of literally tackling everything endoscopy.
