Anal Fistula
What Is An Anal Fistula?
An anal fistula is an abnormal tract that develops between the inside of the anus and the skin around it, typically as a result of an infected anal gland. A fistula can also form following the drainage of a previous perianal abscess that has not closed completely.

Can Anal Fistulas Heal On Their Own?
Most anal fistulas do not resolve on their own. If left untreated, complications of further infection can occur, with recurring discharge of pus and/or blood, alternating with symptoms of pain and swelling around the anus.
Diagnosing Anal Fistulas
An anal fistula can be diagnosed through a detailed assessment involving:
- A review of symptoms, especially a history of repeated swelling and pus discharge
- A physical examination to check for the presence of an abnormal tract
- For complex fistulas, imaging tests to evaluate the full length of the fistula.
Do Anal Fistulas Recur?

Treating Anal Fistulas
An anal fistula usually requires surgery before it can properly heal. The type of surgery used depends on the location and complexity of the fistula.
- Fistulotomy: the most common procedure, which involves opening up the entire tract by cutting along the length of the fistula to enable drainage.
- Seton: suitable for complex fistulas, where a suture or rubber band is placed around the tract to drain the pus.
- Ligation of Intersphincteric Fistula Tract (LIFT): a secure closure for both internal and external openings of the tract.
