Anal fissures are small tears or cuts in the mucosal lining, a thin and delicate lining, of the anus. Passing hard or large stools are one of the main reasons for anal fissures. The resulting tear or cut in the mucosal lining can expose the muscle around the anus known as the anal sphincter. This can cause muscle spasms which can further pull the edges of the fissure.
Most people with anal fissures do not require any extensive treatment unless they do not respond well with the treatments. In such cases, the surgeon might recommend an anal sphincterotomy. In this procedure, a small incision in the anal sphincter is made for the muscles to relax and allow the anal fissure to heal. Here are 5 tips you need to remember after a Sphincterotomy.
