A 46-year-old woman was admitted to our hospital complaining for postevacuative tumor prolapse from the anus and left lower abdominal pain. The tumor, about 5 cm from the anus, was manually reduced, and abdominal computed tomography (CT) showed intussusception in the sigmoid colon, which was reduced using a barium enema. After careful examination, we diagnosed colonic intussusception resulting from lipoma and conducted segmental sigmoidcolectomy assisted by laparoscopy. Pathological examination showed an atypical lipomatous tumor growing from the submucosal layer. The postoperative course was uneventful. Laparoscopic-assisted surgery a preferable in repeated colonic intussusception such as this case.
