Definition. A gastrointestinal fistula is an abnormal opening in the stomach or intestines that allows the contents to leak. 1  Leaks that go through to a part of the intestines are called entero-enteral fistulas.2  Leaks that go through to the skin are called enterocutaneous fistulas.auses. Most gastrointestinal fistulas occur after surgery. Other causes include: 1  Blockage in the gastrointestinal tract. 2  Infection. 3  Inflammatory bowel disease (most often Crohn's disease).
A fistula is an abnormal anastomosis, that is, an abnormal connection between two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs. Fistulas are usually caused by injury or surgery, but they can also result from an infection or inflammation. Fistulas are generally a disease condition, but they may be surgically created for therapeutic reasons.
