Single tunneling method with endoscopic submucosal dissection for treatment of a rectal giant (18-cm) laterally spreading tumor

Abstract

Endoscopic submucosal dissection (ESD) is an effective method for en bloc complete resection of lesions. We report a case of an 18-cm laterally spreading tumor (LST) in the colon that was successfully removed by colorectal ESD using a tunneling technique.
