Surgical management of internal fistulas in Crohn's disease.
BACKGROUND
Internal fistulas in Crohn's disease join a diseased intestinal segment to a "victim organ" (VO) that is affected by proximity. While the diseased segment is resected, the other can be sutured in selected cases.


METHODS
Seventy-four patients with 100 internal fistulas were retrospectively reviewed to assess the results of this conservative operative approach.


RESULTS
Closure of the fistulous defect of the VO was achieved by resection (n = 41) or suture (n = 59). The VO was histologically unaffected by Crohn's disease in 86 cases. One patient died postoperatively. Three patients had postoperative fistulas after suture of the VO. There was no long-term recurrence of an internal fistula.


CONCLUSIONS
Surgical treatment of internal fistulas can be achieved safely by resection of the source of the fistula and suture repair of the VO when the latter is not affected by active Crohn's disease and when local conditions make it feasible.
