The latest edition of this text provides a comprehensive update on the current standards and newest skills in diagnostic endoscopy for pre/neoplastic lesions of the upper and lower gastrointestinal tract. The atlas outlines procedural requirements and strategies for detection and endoscopic staging (prediction of pT category) of small and minute early cancers, and presents endoscopic and high-resolution endosonographic criteria for submucosal invasiveness. The three major resection techniques, including risk profiles, and differential indications and contraindications for each technique are also outlined. In addition to thoroughly revised chapters from the previous edition, the atlas features new content on submuscosal neoplasias in the GI tract, new magnifying images of early gastric neoplasias, and new endoscopic images of adenoma, dyplasia, inflammatory bowel disease, and early cancer in the duodenum and small bowel. Written by experts in the field, Atlas of Early Neoplasias of the Gastrointestinal Tract: Endoscopic Diagnosis and Therapeutic Decisions, Second Edition is a valuable resource that will improve the diagnostic skills of endoscopists.
