Heart A fistula is an abnormal connection between an organ and another structure. Fistulas develop when an organ becomes inflamed or injured. Over half of fistulas form in this location. The second most common location is between 2 loops of intestine.
Treatment[ edit ] There are several stages to treating an anal fistula: Definitive treatment of a fistula aims to stop it recurring. Treatment depends on where the fistula lies, and which parts of the internal and external anal sphincters it crosses. Once the fistula has been laid open it will be packed on a daily basis for a short period of time to ensure that the wound heals from the inside out.
Treatment is usually necessary to reduce the chances of infection in an anal fistula, as well to alleviate symptoms. An anal fistula is defined as a small tunnel with an internal opening in the anal canal and an external opening in the skin near the anus. Anal fistulas form when an anal abscess, that's drained, doesn't heal completely. Different types of anal fistulas are classified by their location.
The anus is the external opening through which feces are expelled from the body. Just inside the anus are a number of small glands. If one of these glands become blocked, an abscess — an infected cavity — may form. An anal abscess is usually treated by surgical drainage, although some drain spontaneously.
