Colon perforation in renal transplant patients.
Six patients with spontaneous colonic perforation after cadaveric kidney transplantation are described. Five perforations occurred in a diverticulum of the sigmoid colon, while one was at the suture line after a colotomy performed 5 months previously. Four patients died. Clinical diagnosis was difficult, but on x-ray examination free air in the abdominal cavity  was found in 3 patients. Explorative laparotomy should be performed promptly when the diagnosis is suspected. All patients above the age of 4o should be screened with a barium enema prior to transplantation.
