An anal fistula is an abnormal channel that develops between the anal canal and the skin near the anus. It may look like a tiny hole in the area of skin surrounding the anus. Anal fistula is commonly caused by an anal abscess that has not been adequately treated. This accounts for up to 80% of all cases. This occurs when one of the glands surrounding the anus become blocked and infected, forming an abscess.
