Endoscopic closure of colonic fistulas in colon cancer patients using a combination of hemoclips and endoloops: two case reports

Abstract

Chronic colon fistulas, which commonly result from operative complications, are generally managed surgically. We present an endoscopic technique of fistula closure that involves the combined use of hemoclips and endoloops. Two consecutive patients with colonic fistulas that were refractory to conservative treatment were successfully managed with this new endoluminal technique. This minimally invasive treatment modality affords accurate localization of the fistula orifice and results in a low mortality and morbidity rates.
