Long-term ileostomy complications in patients with ulcerative colitis and Crohn's disease

Ileostomy complications in 203 patients operated on with proctocolectomy and ileostomy for ulcerative colitis and Crohn's disease were investigated prospectively. The patients were examined at regular intervals by interview and thorough examination of the stoma. Stomal dysfunction was carefully assessed and patients presenting with surgical complications were admitted for reconstruction. The crude rate of ileostomy complications necessitating reconstruction was 34% and significantly higher in patients with Crohn's disease compared with patients with ulcerative colitis. The cumulative rate of surgical revision after 8 years was 75% in the former group and 44% in the latter. Ileostomy stenosis and sliding recession were the two most common indications for reconstruction. Eighty-three per cent of the revisions were performed as local procedures, making a formal laparotomy unnecessary. Causative factors such as surgical technique, length of concomittant ileal resection and postoperative weight gain were analysed for possible influence on the rate of reconstruction, but no significant association was identified.
