Currently, there is no other way to treat anal fistulas but to get the surgery done. In most of the cases, where the fistula is straightforward, the treatment is done with the help of fistulotomy. The procedure involves the unrooting of the tract. The doctors connect the internal opening inside the anal canal with the external opening and create a groove that helps in healing form the inside. Fistulotomy is a long surgical treatment with a success rate as high as 97%. Another way to cure anal fistula is through Fibrin glue injection. This method is opted in the cases when the doctor wants to avoid dividing the sphincter muscles.
