Anal sphincterotomy is a surgical procedure that involves treating mucosal fissures from the anal canal/sphincter. The word is formed from sphincter + otomy (to cut, to separate).
- The surgery can be performed under any kind of anesthesia.
- After anesthesia is administered, the area is cleaned with an antiseptic solution.
- The sphincter is separated either by simply stretching or cutting. Cutting the muscle prevents spasm and temporarily weakens the muscles. Both methods help the underlying area to heal.
- Remove the fissure and any underlying scar tissue.
- Suture back the wound.
