A circumferential rectal superficial neoplasm resected with endoscopic submucosal dissection using the pocket-creation method

Abstract

AbstractEndoscopic submucosal dissection (ESD) is recognized as an important technique in the nonsurgical management of early gastrointestinal carcinoma and it is continuously undergoing evolution in terms of technique and equipment. The pocket-creation method was recently developed for overcoming various difficulties such as large tumor size and severe fibrosis in ESD. Circumferential ESDs are rare and pose technical difficulties. We present a case of a circumferential rectal ESD using a pocket-creation method with two pockets. The associated planning, strategies, and outcome of the procedure are discussed.
