Primary resection and anastomosis for perforated left colon lesions

The records of 33 patients with perforated left colon lesions over a 6-year period from 1992 to 1998 were examined retrospectively for clinical course and complications. All patients had a free perforation, feculent or purulent peritonitis, and/or a large inflammatory mass. All patients had primary resection and anastomosis without a protective colostomy or ileostomy. Indications included diverticulitis in 28 patients, obstructing colorectal carcinoma in 3, and iatrogenic perforations in 2. Complications occurred in 10 patients, including atelectasis in 1, urinary retention in 2, urinary tract infections in 2, wound infections in 3, line catheter sepsis in 1, and acute tubular necrosis in 1. There was one anastomotic dehiscence, which was successfully converted to a Hartmann procedure. Patients were discharged an average of 7 days after surgery. Two patients required surgery after discharge: one had a fascial dehiscence and the other an incisional ventral hernia. There was no mortality. Primary resection and anastomosis of selected perforated left colon lesions can be performed with a morbidity and mortality rate lower than that usually reported for the Hartmann procedure.
