Dr. Shen is the head and medical director of the IBD Center at Columbia. He is also the Vice Chair for Innovation in Medicine and Surgery and a Professor of Medicine (in Surgery). He is one of the world’s pre-eminent leaders in interventional inflammatory bowel disease (IBD) due to his specialized expertise in treating a wide range of pouch-related disorders. In addition to pouchitis and pouch diseases, Dr. Shen specializes in IBD, GI endoscopy (including endoscopic pouch procedures), and imaging technology. Dr. Shen is known as a pioneer in interventional treatment for IBD - this includes postponing or eliminating the need for surgery in some cases.
"""This book is a high-quality compilation of both common and uncommon endoscopic presentations of inflammatory bowel disease, malignancy (both CAN as well as lymphoma), and IBD mimickers. Unlike other textbooks on IBD, such as Inflammatory Bowel Disease: Diagnosis and Therapeutics, 3rd edition, Cohen (Springer, 2017), this book is intended to be a quick source of reference for pathology encountered during endoscopic surveillance rather than a comprehensive overview of epidemiology, biologic therapeutics, and clinical management strategies."" --Doody"
