Ileocecal Intussusception Caused by Intestinal Lipoma, Resected by the Laparoscopic Operation

Abstract

A 52-year-old woman was admitted to our hospital with six month's history of colicky right lower abdominal pain. Colonoscopy revealed ileo-colic intussusception induced by a 4 cm submucosal tumor of ileum with overlying ulceration of the mucosa. Enhanced computed tomography demonstrated the presence of ileo-colic intussusception and further showed that the leading point of intussusceptions was fat attenuation of 4cm in diameter. We diagnosed ileo-colic intussusception caused by the ileal lipoma and was treated by laparoscopic ileocecal resection. We found the invagination and an egg-sized tumor at the leading point during laparoscopic operation. The resected specimen contained a round yeallowish submucosal intraruminal mass, which was histopathologically identified as an intestinal lipoma. Recently, it has been reported that intussusception caused by small intestinal lipoma can be diagnosed preoperatively and treated with similar approach and technique for laparoscopic surgery for colon resection. Therefore, laparoscopic surgery for intussusception caused by small intestinal lipoma is recommended as less invasive procedure.
