Entero-enteral fistula; Enterocutaneous fistula; Fistula - gastrointestinal
Depending on the part of the intestines that are leaking, gastrointestinal fistulas may cause diarrhea, malabsorption of nutrients, and dehydration.
- Entero-enteral fistulas may have no symptoms.
- Enterocutaneous fistulas cause leakage of intestinal contents through an opening in the skin.
Signs and tests:
- Barium swallow (to identify a gastrointestinal fistula)
- Barium enema (to identify a fistula involving the colon)
- CT scan of the abdomen (to identify fistulas between loops of the intestines or an area of infection, called an abscess, associated with the fistula)
- Fistulogram (involves injecting contrast dye into the opening of the skin of an enterocutaneous fistula and then taking x-rays)
