A gastrointestinal fistula is an abnormal opening in the stomach or intestines usually caused by an injury, surgery, infection or inflammation. Fluids from your stomach or intestines will leak through the opening into other parts of your body. Fistulas can sometimes close on their own, but when they don’t a Gastroenterologist can use endoscopic procedures to close the fistula in a minimally invasive way. Our specialists use both the Padlock Clip Device and the Over-The-Scope (OTSC) device to close GI fistulas.
