Enterocutaneous Fistula
Condition
(Gastrointestinal Fistula; Entero-enternal Fistula)
Definition
An enterocutaneous fistula is an abnormal connection between the intestines and the skin. Intestinal or stomach contents can leak through it. They may also leak into another part of the body or outside of the body.
This problem needs to be treated right away.

Causes
Most of the time, an enterocutaneous fistula happens after bowel surgery. Other causes are:
- Infection
- A duodenal ulcer that breaks open
- Bowel disease, such as Crohn disease, ulcerative colitis, or diverticulitis
- Trauma, such as a gunshot or stabbing
- Cancer
- Cancer treatment, such as radiation therapy
Risk Factors
Things that may raise the risk of an enterocutaneous fistula are:
- Recent bowel surgery
- History of radiation therapy
Symptoms
Problems may be:
- Contents from the intestines that leak from an opening in the skin
- Loose stools (poop)
- Belly pain
Diagnosis
The doctor will ask about symptoms and past health. A physical exam will be done. The person may be referred to a colon and rectal surgeon.
Images may be taken with:
- CT scan to view the belly
- Ultrasound to view the belly
- Barium enema to view the colon and rectum using contrast material
- Barium swallow test to view the digestive system using contrast material
- Fistulogram to view the fistula using contrast material
Treatment
The goal is to help the enterocutaneous fistula heal. It is also to prevent or treat complications. An uncomplicated fistula may heal on its own over 2 to 8 weeks. Care during this time may be:
- Nutritional support, such as diet changes, IV nutrition, or a feeding tube
- Medicines to:
- Prevent or treat an infection
- Ease pain
- Reduce stomach acid and leaking fluids
- A drain to remove leaking fluids
Surgery will be done to close the opening—if it does not heal on its own.
Underlying causes, such as bowel disease, will also need to be managed.
Prevention
There are no known guidelines to prevent an enterocutaneous fistula.
