Acute Management of Stoma-Related Colocutaneous Fistula by Temporary Placement of a Self-Expanding Plastic Stent

Abstract

Colocutaneous fistulas are frequently the result of complications related to previous operative procedures and are a major cause of morbidity. Most are initially treated conservatively, with a large percentage eventually requiring further surgery for definitive treatment. The use of a temporary colonic stent for the management of colostomy-related colocutaneous fistula has not been previously described. Two patients with colocutaneous fistula related to end colostomies and opening into midline laparotomy wounds were treated by temporary plastic stenting. A removable Polyflex silicone stent was inserted into the stoma. Stent redeployment was needed on several occasions following partial stent expulsion. Midline wound healing was achieved in both cases by 6 weeks post—stent insertion, and complete fistula closure occurred in 1 case. Temporary stent placement in certain cases may aid in the management of a colocutaneous fistula associated with a colostomy to allow fecal diversion from wounds and aid fistula closure.
