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).
These fistulas may form a connection between the bladder and the vagina (vesicovaginal), the skin of the abdomen (vesicocutaneous), or the intestinal tract. Fistulas that connect to any part of the intestine are collectively referred to as vesicoenteric fistulas.Fistulas between the bladder and intestine can occur at the colon (colovesical, most common), rectum (rectovesical), ileum (ileovesical), or the appendix (appendicovesical).The result of any of these conditions is a free exchange of fluids between the bladder and the area connected by the fistula.istulas between the bladder and intestine can occur at the colon (colovesical, most common), rectum (rectovesical), ileum (ileovesical), or the appendix (appendicovesical).
