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).
Procedure
# The surgery can be performed under any kind of
anesthesia
Anesthesia is a state of controlled, temporary loss of sensation or awareness that is induced for medical or veterinary purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), ...
.
# 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.
