The indications for surgery were intestinal perforation (28), intestinal obstruction (7), clinical deterioration (1) and persistent rectal bleeding (1). The initial procedure was percutaneous peritoneal catheter drainage (13), intestinal diversion alone (8), intestinal resection (14), laparotomy and biopsy (1) and laparotomy alone (1).
