Abstract
Lipomas are benign soft tissue tumors found throughout the body including the gastrointestinal (GI) tract. Colonic lipomas are typically asymptomatic, incidentally identified during endoscopy or at the time of autopsy. However, giant lipomas larger than 4 cm usually manifest symptoms such as abdominal pain, obstruction, melena or intussusception. The transverse colon is the least common location for colonic lipoma. We report on a 54-year-old man with acute large bowel obstruction secondary to a long segment colo-colonic intussusception from a giant lipoma originating in the transverse colon. The diagnosis was suggested by advanced imaging and confirmed on endoscopy. He was treated successfully by laparoscopic extended right hemicolectomy with ileocolonic anastomosis. This case highlights the complexity of presentation and surgical management of large bowel obstruction and colonic intussusception, as well as the rare entity of giant colonic lipoma.
