(Sphincterectomy, Anal; Surgery for Anal Fissures; Lateral Internal Sphincterotomy; LIS)
Pronounced: A-nul Sfink-ter-ot-o-me
Sarah J. Kerr, BA
This is a procedure to treat chronic anal fissures. An anal fissure is a painful tear in the lining of the anus. The anus is the opening through which stool passes from the body. Tears generally occur just inside the opening.
If there are any skin tags near the fissure, they will be removed. Next, the doctor will carefully make a cut on the anal sphincter muscle. This will relax the sphincter and allow it to stretch, taking pressure off the fissure. The doctor will put a dressing into your anus to stop the bleeding.
