Initial clinical experience with a bipolar snare for colon polypectomy.

A bipolar snare was used for colon polypectomy in 86 instances in 61 patients. There were 20 pedunculated polyps ranging in size from 0.3 to 1.5 cm and 66 sessile polyps ranging in size from 0.3 to 4.0 cm. The power output selected ranged from 16 to 30 W on a bipolar electrosurgical generator. No perforation, transmural burn, or post-polypectomy bleeding was encountered. Minimal immediate oozing from a polypectomy stalk required iced-saline lavage but was easily controlled. The bipolar snare is a useful and safe addition to the endoscopic surgeon's armamentarium.
