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).
In more severe cases, Crohnâs can lead to tears (fissures) in the lining of the anus, which may cause pain and bleeding, especially during bowel movements. Inflammation may also cause a fistula to develop.
