Sphincterotomy for Anal Fissure

By | September 27, 2018

A sphincterotomy is a simple method that has established to be highly successful in the treatment of anal fissures. You will be encouraged to go for other treatment methods before surgery, and when these methods are ineffective, you will be suggested this surgery. Side effects are very rare and can be treated if they do occur. A sphincterotomy is a simple surgery in which the sphincter is cut or stretched. The sphincter is the circular group of muscles neighboring the anus and are responsible for controlling bowel movements.


Lateral internal sphincterotomy includes stretching or cutting the inner sphincter, the muscle that limits and relaxes when stool passes from the body. Cutting the muscle avoids spasm and momentarily weakens the muscles, and this, in turn, helps the area to heal. The doctor eliminates the fissure and any underlying scar tissue.

The surgery may be done under local anesthesia, that involves injecting the affected area with a numbing agent, or spinal anesthesia, which numbs the whole lower body. Occasionally, general anesthesia may also be used, which makes the patient unconscious. The selection of anesthesia depends on the choice of patient and physician according to the patient’s health, and the standard practice of the particular facility.

The patient is placed on the table so that the anus and rectal area are exposed. This may be done face down, with the buttocks a little elevated. After anesthesia is given, the area is cleaned with an antiseptic solution.

The operation takes about 25 to 30 minutes. And then the wound is sutured closed, generally with stitches that dissolve in time. Mostly, patients can go home on the same day of the procedure.


Normally, it will take about six weeks for your anus to fully cure, but the majority of people are able to start again their normal activities including going to a job within one to two weeks after the surgery.

This is definitely a proven treatment but laser has turned out to be most advanced and painless treatment for fistula.
