Colonic Intussusception across the Splenic Flexure Due to a Submucosal Tumor in the Transverse Colon Successfully Treated by a Single-Incision Laparoscopic Surgery (Case reports)

A 28-year-old man was referred from a local clinic to our hospital owing to bloody stool and left lower abdominal pain. Computed tomography demonstrated intussusception of the colon in the left lower quadrant which was reduced with a barium enema. A submucosal tumor approximately 6 cm in diameter was found with colonoscopy in the transverse colon and was suspected to be a lipoma. Although an elective operation was planned for the following week, the patient underwent emergency surgery owing to a recurrent intussusception with severe abdominal pain. Observation during single-incision laparoscopic surgery detected a colonic intussusception in the left lower abdomen. After the intussusception was reduced with a laparoscopic procedure, the tumor was found near the splenic flexure of the transverse colon. The splenic flexure was apart from the spleen owing to a loose ligamentous connection between the colon and the spleen which was thought to be the cause of colonic intussusception across the splenic flexure. The patient successfully underwent partial colectomy and reconstruction with a functional end-to-end anastomosis by means of single-incision laparoscopic surgery. (Jikeikai Med J 2015 ; 62 : 69-72)
