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

Colonic lipomas are benign adipose tumors that do not usually cause symptoms. Giant colonic lipoma (GCL) is an uncommon finding at endoscopy which may lead to iron deficiency anemia (IDA) with or without macroscopic ulceration. The choice of therapeutic procedure to treat symptomatic GCLs has been controversial. A case of GCL presented with occult bleeding and IDA is reported in this article. IDA resolved following the successful removal of the GCL by a combination of endoloop ligation and snare cautery technique.
