May 2, 2020 at 7:40 am

An anal fistula (also known as fistula-in-ano) is characterized by chronic purulent drainage through a formed tract typically from an abscess cavity around the anus or rectum. As the pus drains, a small tunnel is created between the skin and abscess cavity. Patients commonly seek treatment due to presence of pain, swelling, and a foul-smelling discharge.
