Fistula is a kind of tube-shaped passage between two organs. It can also occur between a hollow or tubular opening and any other tissue of the body. Fistula can occur in different parts of the body. Anorectal fistula is the most common type of fistula. Surgery is required to cure some fistulas. However, by changing daily activities, fistula can be prevented or avoided.
