Information about Anal Fistula
We Have to Know about the Anal Fistula
- The anus is the muscular canal through which stool passes out of the body.
- An anal fistula is an abnormal, narrow, tunnel-like passageway that connects the anal canal, through the remains of an old anal abscess, to the surface of the skin.
Causes of Anal Fistula
- An anal fistula develops in about half of all anal abscesses that have drained. Sometimes, the opening of the fistula at the skin surface leaks a thick, foul-smelling liquid.
- In other cases, the opening of the fistula eventually becomes blocked with draining debris, causing the old anal abscess to spread outward again as a firm pocket of pus.
