underwater endoscopic mucosal resection achieves similar rates of complete resection with comparable safety, with lower rates of recurrence and fewer repeat procedures.

Current guidelines recommend preoperative hot snare polypectomy after preoperative saline injection, nylon ring, or metal clip ligation of the tip and pedicle of the polyps
