An anal fistula is a tunnel that forms underneath the skin in the anal region. The fistula connects an infected anal gland inside the anus to the skin around the opening of the anus. It usually occurs when an anal abscess is untreated and the infection worsens and spreads from the anal gland to the surface of the anus. However, a fistula can also occur due to:
- Rectal cancer
- STI’s (sexually transmitted infections)
- Crohn’s disease
- Anal tuberculosis
This is a serious colorectal condition and requires immediate medical attention. According to the World Health Organization, from 50,000 to 100,000 new cases of anal fistulae are reported each year worldwide. Of these, 30% to 50% of patients start with an anal abscess that worsens into a fistula.
