Diverting loop versus end ileostomy during ileoanal pullthrough procedure for ulcerative colitis.

A two-stage ileoanal pullthrough procedure (IAPP) is often used for patients with ulcerative colitis (UC) requiring proctocolectomy. We analyzed the recent University of California at Los Angeles experience with diverting end and loop ileostomies in patients undergoing a two-stage IAPP. A retrospective analysis of 21 patients with UC undergoing loop ileostomy between March 1992 and March 1995 was performed. Comparison was made with 21 age- and gender-matched patients undergoing end ileostomy between January 1991 and December 1995. There was no mortality or major septic complications. A second laparotomy was required in all patients with end ileostomies, whereas loop ileostomies were closed without abdominal exploration. During ileostomy closure, operative time and mean hospital stay were significantly reduced with the use of loop ileostomy. The time to oral feeding was not significantly different between end and loop ileostomy groups after ileostomy closure. The complication rate after IAPP was similar between groups. However, after ileostomy closure, the complication rate was significantly reduced with the use of loop ileostomy. We conclude that loop ileostomy is a desirable option for UC patients undergoing intestinal diversion during IAPP. Loop ileostomies can be created easily and without an increase in operative time. Subsequent ileostomy closure can be performed as a local procedure, which may shorten operative time and length of hospital stay.
