A Method for Endoscopic Electroresection of Sessile Colonic Polyps

Abstract

The endoscopic removal of sessile polyps in the proximal colon in man by a diathermy loop may cause perforation. Injection of a fluid depot under the colonic mucosa in dogs prevents sufficiently coagulation of the underlying intestinal wall during diathermic removal of mucosal specimens. With this method 7 sessile colonic polyps in man were endoscopically removed with a diathermy loop without complications.
