Endoscopic Full-Thickness Resection of Proximal Ascending Colonic Intramucosal Carcinoma by FTRD Device: Saving the Colon

Abstract

The full-thickness resection device (FTRD) allows for endoscopic full-thickness resection of gastrointestinal lesions up to 3 cm. This transluminal endoscopic minimally invasive technique allows safe closure after full-thickness resection, thereby providing an en-bloc specimen for histological examination and resection with minimal thermal damage. Using the device for lesions in the proximal ascending colon and cecum is technically challenging. Herein, we describe a case of JNET 2A/2B proximal ascending colonic polyp on both sides of the fold, which was resected safely by the FTRD device, and the en-bloc resected specimen turned out to be intramucosal carcinoma.
