Endoscopic Resection of a Large Colonic Lipoma / 대한소화기내시경학회지

ABSTRACT

Although colonic lipomas constitute the most common nonepithelial neoplasms of the gastrointestinal tract, colonic lipomas are rare benign tumors. Most colonic lipomas are asymptomatic and are incidentally identified at the time of endoscopy or surgery. Lipomas may cause symptoms such as bleeding, obstruction or intussusception when the size of a tumor exceeds 2 cm. Surgical resection is recommended for larger lipomas to relieve symptoms or exclude a malignancy. There are few published reports on the endoscopic removal of colonic lipomas. Endoscopic snare polypectomy has been used to treat clinically symptomatic colonic lipomas. However, removal of lipomas 2 cm or greater in diameter has been associated with a greater risk of perforation. Using a detachable snare or hemoclipping may reduce the risk of complications after a polypectomy. We report a case of a large colonic lipoma that was treated with endoscopic polypectomy using a detachable snare and hemoclipping.
