Abstract

A 73-year-old woman presented with intermittent abdominal pain and weight loss of 15 kg for 2 years. Colonoscopy revealed an erythematous polypoid tumor with a long and wide stalk in the cecum, but with air inflation, it abruptly went away through the ileocecal valve (ICV). An abdominal computed tomography showed a well-demarcated pedunculated subepithelial mass of 2.6x2.7 cm size with fat attenuation in the terminal ileum. It was an intussusceptum of the ileal lipoma through the ICV. This ileal lipoma was causing her symptoms because repeated ileocolic intussusceptions resulted in intermittent intestinal obstructions. In order to avoid surgical sequelae of ileal resection, snare polypectomy using cap-assisted colonoscopy technique was performed within the ileum without complications. The histopathology report confirmed it as a subepithelial lipoma. After endoscopic resection of the ileal lipoma, the patient has been free of symptoms and was restored to the original weight.

(C) Hemoclipping at the base of the resected portion of the ileum to prevent delayed hemorrhage and perforation.
