Crohn's colitis: the fate of the rectum

Previous reports suggest that up to 70% of patients undergoing surgery for Crohn's disease of the large bowel do not have gastrointestinal continuity restored and require a permanent ileostomy. In this study the experience with patients requiring surgical treatment of large bowel Crohn's disease is reviewed with particular reference to the management of the rectum. The records of 19 elective and 25 urgent colonic resections performed for large bowel Crohn's disease in 44 patients (16 males, 28 females; mean age 41 years, range 17-76) between 1983 and 1995 were reviewed. Staged proctectomy was performed in 5 of 12 patients who had colectomy for acute colitis and in one patient who had had an elective colectomy. Permanent ileostomy was required in 72% of patients with acute Crohn's colitis and 84% of patients who had elective surgery for large bowel Crohn's. Over 70% of patients having surgical treatment of Crohn's disease of the large bowel required permanent ileostomy. No cases of cancer developed in patients with retained rectal stumps.
