Endoscopic mucosal resection with a dedicated bipolar soft snare for large flat colonic polyps.

When removing large flat colonic polyps (LFCPs) en bloc endoscopic submucosal dissection (ESD) may be suitable; however, it requires significant expertise and a long procedural time. The use of a conventional monopolar snare for endoscopic mucosal resection (EMR) of large lesions increases the risk of deep mural injury [1]. Bipolar snares are safer than monopolar snares because the current passes only through the tissue between the two electrodes, so causing minimal damage to the muscle layer [2].
