Duplication of the colon and rectum in the adult is a rare anomaly. A 26-year-old man with recurrent episodes of pneumatouria and lower abdominal pain visited our hospital. Barium enema showed a duplicated colon at the sigmoid colon which ended blindly in the pelvis. Cystoscopy revealed incomplete duplication of the urinary bladder, but the communication between the urinary bladder and the duplicated colon was not detectable on cystography. X-ray of the vertebral column showed spina bifida of the sacrum. Resection of the duplicated colon on the mesenteric side of the sigmoid colon and the partial resection of the urinary bladder were performed. The resected specimen showed a tubular duplicated colon measuring 30 cm in length which had histologically normal structure of he colonic wall.
