Anal Fistula
Recurrent discharge or pus around the anus should be assessed.
An anal fistula is an abnormal tract between the inner part of the anal canal and the surrounding skin. It often develops after an abscess or infection and usually does not heal completely with antibiotics alone.
When should you be assessed?
- Recurrent pus or discharge
- Swelling or pain near the anus
- A recurring abscess
- A small opening in the skin around the anus
- Repeated irritation or bleeding
How is it assessed?
- Clinical examination
- MRI fistula mapping for complex cases when required
Treatment Options
The aim of treatment is to heal the fistula while protecting the anal sphincter and maintaining continence. Options include fistulotomy, seton placement and sphincter-sparing techniques in suitable cases. The most appropriate technique depends on the tract and complexity of the fistula.
