A Case of Intussusception Caused by Trans-anal Ileus Tube Insertion for Synchronous Multiple Colon Cancer

Abstract

A 59-year-old man was admitted with constipation and lower abdominal pain. Plain abdominal radiographs showed a dilated colon, and abdominal computed tomography (CT) showed a thickened wall of the sigmoid colon. Colonofiberscopy showed the mass occupying the lumen of the sigmoid colon, and a trans-anal ileus tube was continuously inserted. After colon cleaning and decompression, enhanced CT showed the mass in the transverse colon and the liver, in addition to the sigmoid colon. The next day, a barium enema showed the obstruction of the descending colon caused by intussusception of the transverse colon mass. The added pressure reduced the intussusception. Surgery was performed 7 days after ileus tube insertion. Trans-anal ileus tube insertion is used in preparation for the obstructive colorectal cancer surgery, and is useful to detect proximal colon lesions. Complications of trans-anal ileus tube insertion such as bleeding, perforation, and ulceration have been reported. We report a case of intussusception caused by trans-anal ileus tube insertion. Intussusception should be noted as a complication of trans-anal ileus tube insertion because synchronous, multiple colorectal cancer is not considered a rare condition.
