Crohn's Disease Complicated by Ileosigmoid Fistula - Synchronous Resection or Primary Sigmoid Repair, One or Two-stage Procedure? A systematic review of the literature and prospective case series.

Primary repair should be attempted in all cases in which the sigmoid colon is disease-free or is not involved in the adja-cent abscess. The synchronous resections are not a mandatory indication for the stoma, but rather a tailored approach is recommended with an evaluation of the risk factors. Based on the available literature, no clear recommendation regarding the type of stoma can be made.
