Ileorectal Anastomosis for Ulcerative and Crohn's Colitis

Except in the presence of severe perineal suppuration or sphincter damage by previous surgery for fistulas, the rectum was preserved in all patients considered candidates for surgery for inflammatory disease of the bowel. A primary anastomosis with a single-layer 5-0 monofilament stainless steel wire was carried out when a relatively healthy rectum with erythema and granularity presented. For patients with more severe disease of the rectum, a two-stage operation with intensive interval treatment of the rectum stump with topical corticosteroids was carried out. Of a total of eighty-six patients with involvement of the colon and rectum with either Crohn's disease or chronic ulcerative colitis, fifty-six patients were treated by local abdominal colectomy and ileorectal anastomosis. Twenty-four had primary anastomosis and thiry-two had a two-stage operation. One anastomotic dehiscence developed. A mean follow-up of 8.4 years (6 months to 20 years) has been satisfactory. Only three anastomoses have been taken down for unsatisfactory results. With the proper selection of patients and with appropriate treatment of the diseased rectal segment, a large majority of patients with inflammatory disease of the bowel can have long-term salutory results after colectomy and ileorectal anastomosis.
