Endoscopic Closure of a Postablation Colorenal Fistula Using a Through-The-Scope Helical Suturing System

Colorenal fistulae are a rare complication after percutaneous ablation of renal cell carcinoma tumors. Through-the-scope suturing (TTSS) is becoming increasingly used in the repair of gastrointestinal defects, including fistulae and perforations. We describe a technically and clinically successful case of endoscopic closure of a left-sided colorenal fistula using TTSS. TTSS is safe, relatively low cost, and easy to learn. It can be considered as an initial therapy in the closure of colonic fistulae, before proceeding to surgery, which carries significantly higher morbidity.
