PURPOSE: This study analyzes the impact of a temporary loop ileostomy on postoperative outcome after restorative proctocolectomy for ulcerative colitis in terms of complications and reoperations including ileostomy closure. METHODS: The records of 122 consecutive patients undergoing restorative proctocolectomy for ulcerative colitis during a 12-year period were reviewed. In 89 patients, a defunctioning ileostomy was created, while 33 patients had no ileostomy. Statistics were done with Chi-square test and Mann-Whitney U test, p < 0.05 considered significant. RESULTS: Both study groups were comparable concerning age, colitis activity, previous diseases, previous surgery, use of steroids, and immunosuppressives. Pouch-related septic complications (anastomotic dehiscence, pouch leakage, pelvic abscess) were significantly lower in the ileostomy group (5.6% vs. 18.2%, p = 0.031), resulting in a lower rate of emergency laparotomies following restorative proctocolectomy (4.5% vs. 30.3%, p < 0.001). Including all complications associated with scheduled closure of ileostomy, the cumulative frequency of emergency laparotomies was significantly lower in the ileostomy group (13.5% vs. 30.3%, p = 0.032). The cumulative duration of hospitalization, including all hospital stays for complications or closure of the ileostomy, was significantly longer in the ileostomy group [median 22 days (11-92) vs. 14 days (9-109), p < 0.001]. During long-term follow-up, a stricture at the pouch-anal anastomosis was more common in the ileostomy group (24.7% vs. 6.1%, p = 0.021), whereas only one stricture necessitated surgical therapy. CONCLUSIONS: Creation of a defunctioning loop ileostomy reduces pouch-related septic complications and the frequency of emergency second laparotomies after restorative proctocolectomy for ulcerative colitis.
