Clinical Information
  • An abnormal anatomical passage between the intestine, and another segment of the intestine or other organs. External intestinal fistula is connected to the skin (enterocutaneous fistula). Internal intestinal fistula can be connected to a number of organs, such as stomach (gastrocolic fistula), the biliary tract (cholecystoduodenal fistula), or the urinary bladder of the urinary tract (colovesical fistula). Risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (medical errors).
  • An abnormal communication between the small or large intestine and another organ or cavity.
