What is Anal Fistula?

An anal fistula is an abnormal tunnel that forms between the inside of the anal canal and the skin near the anus, most commonly developing as a complication of a previously drained perianal abscess. The tract allows persistent drainage of pus or fluid and rarely heals on its own without treatment, often causing recurrent infections if left unaddressed. It can be associated with underlying conditions such as inflammatory bowel disease, particularly Crohn's disease, which should be considered and evaluated, especially in cases of recurrent or complex fistulas.

What are the main symptoms of Anal Fistula?

The most common symptoms include: Persistent drainage of pus; blood; or fluid near the anus; recurring pain and swelling. Early recognition is key to prompt diagnosis and effective treatment.

Is Anal Fistula contagious?

No, Anal Fistula is not contagious. It cannot spread through casual contact. However, certain risk factors and genetic predispositions may increase susceptibility.

How is Anal Fistula treated?

Treatment options include: Surgical treatment is generally required since fistulas rarely close on their own; with options including fistulotomy; where the tract is opened and allowed to heal. Treatment should always be guided by a qualified Colorectal & Proctology specialist. Do not self-medicate.

Can Anal Fistula be prevented?

While Anal Fistula cannot always be fully prevented, several measures can reduce risk: Prompt and complete drainage of any anal abscess to reduce fistula risk; good anal hygiene; early management of inflammatory bowel disease.

When should I see a doctor for Anal Fistula?

Consult a Colorectal & Proctology specialist if symptoms persist for more than a few days, worsen despite home care, or significantly affect your daily activities. Early diagnosis leads to better outcomes.
