Anal Fistula

This often presents first as an abscess, but is actually a small tunnel that runs from within the anus to an opening in the skin around the anus. This occurs when glands within the anus become clogged and infected. Symptoms include:

  • Pain
  • Swelling
  • Bleeding
  • Fever
  • Bloody or purulent drainage
  • Irritation of the skin around the anus
  • Recurrent anal abscess


Your doctor will ask about your medical history and perform a physical exam. CT scan, MRI or colonoscopy exam in the OR might be necessary to achieve an accurate diagnosis.


Treatment can vary from a simple outpatient surgery to a series of planned procedures to heal a fistula. Procedures may include removal of the track of the fistula. Depending on the location and severity of the fistula, your doctor may need to drain the fluid prior to the curative surgery.
