Underwater reopenable clip closure of mucosal defects after duodenal endoscopic submucosal dissection.

Abstract

Closing mucosal defects after duodenal endoscopic submucosal dissection (ESD) decreases the risk of postoperative adverse events.1 Although various methods for closure have been proposed,2,3 a single reliable and safe method has not yet been established. Herein, we propose the underwater reopenable clip closure (U-REC), a novel technique for closing mucosal defects after duodenal ESD.
