The exteriorized anastomosis: its role in surgery of the colon.

Sixty-one patients (59, trauma; two, nontrauma) have been managed at Detroit General Hospital from 1972 to 1976 utilizing an exteriorized colon anastomosis. Healing of the anastomosis was present in 42 (70%) of the patients, and 37 (62%) avoided colostomy. Our experience with this procedure has demonstrated that it is a safe, reliable adjunct to be used in colon surgery when primary intraperitoneal repair is not desirable, that the added operating time (20 to 30 minutes) will not be deleterious to the patient, that the lesion is at least 18 cm above the peritoneal reflection, and that the likelihood of a prolonged septic postoperative course is not high.
