Surgical load and long‐term outcome for patients with Kock continent ileostomy
Abstract
OBJECTIVE: The aim of the study was to evaluate the results of Kock continent ileostomy (CI) during the same period when ileal pouch-anal anastomosis was the preferred operation for patients with ulcerative colitis (UC) or familial adenomatous polyposis (FAP). METHOD: During the period 1983-2002, 50 patients underwent CI. The surgical technique was unchanged during the period. Follow-up included all patients. Forty-eight patients had UC, two of these had the diagnosis later changed to Crohn's disease and two had FAP. RESULTS: Twenty-two patients had 38 reoperations, four (8%) of whom had the pouch removed. The main causes for reoperation included leakage and difficulty in intubation due to sliding of the nipple valve (42%), fistula formation (29%) and stenosis (21%). Seventeen (45%) underwent a revision of the nipple valve and the pouch and nine (24%) a local procedure. The reoperation rate was higher among patients having a conventional ileostomy converted to CI than among those having CI. As a primary procedure (P = 0.016). The risk of a second reoperation was higher for those reoperated within the first year after having a CI, than for those reoperated later (P = 0.007). CONCLUSIONS: The reoperation rate of patients with CI is high but the removal rate of the pouch is low and is not associated with a high rate of revision. CI is a good alternative to conventional ileostomy in patients not suitable for restorative proctocolectomy or where this procedure has failed.
