What is anal fistula?

This is a condition where a tunnel forms between the anus and the skin surrounding the anus. Patients are prone to recurrent infection of the area, and this is often associated with inflammatory bowel disease like Crohn's disease.

Symptoms of anal fistula

  • Hemorrhoids (piles) or a lump at the anus

  • Pain over the anus

  • Pus from around the anus or anus itself

  • Itching around the anus

  • Swelling of the affected area

Questions your doctor may ask to check for anal fistula

Your doctor may ask these questions to diagnose anal fistula

  • Do you have hemorrhoids (piles) or a lump at the anus?

  • Do you have anal pain?

  • Do you have pus from around the anus or anus itself?

  • Do you have itching of the anal region?

  • Is the affected area swollen?

Treatment for anal fistula

Surgery is usually required as they rarely heal on their own. Treatment of the underlying cause (e.g. bowel inflammation) is needed to prevent fistulas from returning.
