Gastroenterological Endoscopy

Description:

Praise for the previous edition:
"Extraordinary achievement … this volume stands on its own as a marvelous feat in bringing such a vast array of clear and coherent instruction to endoscopists at all skill levels."—Gastroenterology

Written and edited by internationally renowned specialists, the third edition of Gastroenterological Endoscopy covers the entire spectrum of diagnostic and therapeutic procedures for the upper and lower GI tract while providing the latest overview of GI disorders. A great wealth of high-resolution photographs provides the visual information needed to confidently assess and diagnose mucosal lesions of the entire digestive tract. Significant advances in the field—both medical and technical—since the last edition are covered in comprehensive detail.

Key Features:

New panel of top international editors, continuing the tradition of excellence, depth, and breadth as originated by founding editors Classen, Tytgat, and Lightdale; list of contributing authors is a "who's who" of GI endoscopy

Coverage of newest, advanced tools and techniques: gastric-POEMS, submucosal tunnel endoscopic resection (STER), lumen-apposing metal stents, "over-the-scope" clips, and much more

More than 1,500 exquisite images

Gastroenterological Endoscopy, third edition, surely deserves a prominent place in any complete endoscopy reference collection.
