Laparoscopic Surgery for an Intussusception Caused by a Lipoma in the Ascending Colon

A colonic intussusception caused by an intraluminal lipoma is a rare disease in adults, in whom it usually has a definite or-ganic cause. In fact, it is either caused by a benign or a malignant condition, both of which occur at similar rates. However, little literature is available on laparoscopic procedures for use in cases of adult colonic intussusceptions. Recently, a 52-year-old woman was admitted to our hospital with abdominal pain of one-month duration. Abdominal computed tomography showed an intussusception with a fat-containing mass in the right hepatic area. Colonoscopy showed a colon lumen occu-pied by the mass. A right hemicolectomy was performed laparoscopically, and the cause of the intussusception was found to be a lipoma. Before obtaining histological confirmation, we carefully perform a laparoscopic procedure, which required consideration of the relations between the involved colonic segment and other conditions such as the location of main ves-sels, the anatomical exposure with respect to colonic mobilization and the location of specimen retrieval
