What Is an Anal Fistula?

An anal fistula is a small tunnel that runs from an opening inside the anal canal to an outside opening in the skin near the anus. An anal fistula often results from a previous or current anal abscess. As many as 50 percent of people who have an abscess get a fistula, but a fistula can also occur independently.
