Endoscopic resection of large colonic lipomas assisted by a prototype single-use Endoloop device

Colonic lipomas are benign adipose tumors that occasionally cause symptoms. Endoscopic resection of large lipomas may be associated with the risk of hemorrhage or perforation. Experience with endoscopic resection of colonic lipomas with the assistance of a prototype single-use ligating Endoloop device, with a detachable snare unit, has not been previously reported. Three patients with a total of four large symptomatic colonic lipomas successfully underwent endoscopic resection with the aid of this device. One patient had self-limiting minor rectal bleeding which settled without consequence. All patients were well on follow-up, with resolution of their symptoms. This novel endoscopic technique should be considered during resection of large lipomas (> 10 mm diameter) to reduce the potential risk of bleeding.
