Anal Fissures Surgery
A chronic fissure that is not healing may warrant surgery. Surgery is not usually the first treatment but is used after other treatment methods have failed to bring relief. There are a couple different options for surgery. One is an injection of a liquid similar to Botox into the anal sphincter. This numbs the area and prevents the sphincter from going into painful spasms.
Another option is to cut away a small portion of the sphincter. While this does not necessarily cure the fissure, it will give you relief. The likelihood of the fissure returning after this procedure is slim.
If you are having pain and/or bleeding after a bowel movement, see your healthcare provider for the correct diagnosis before trying to treat yourself.
