A lateral internal sphincterotomy is a simple surgery during which the sphincter is cut or stretched. The sphincter is the circular group of muscles surrounding the anus that are responsible for controlling bowel movements.
This type of sphincterotomy is a treatment for people who suffer from anal fissures. Anal fissures are breaks or tears in the skin of the anal canal. A sphincterotomy is used as a last resort for this condition, and people who experience anal fissures are usually encouraged to try a high-fiber diet, stool softeners, or Botox first.
There are several other procedures that are often performed alongside a sphincterotomy. These include a hemorrhoidectomy, a fissurectomy, and a fistulotomy. You should check with your doctor to see precisely which procedures will be performed and why. During the procedure, the surgeon makes a small incision in the internal anal sphincter. The aim of this incision is to release the tension of the sphincter.
When the pressure is too high, anal fissures are unable to heal. A sphincterotomy can be performed under local or general anaesthetic, and you will normally be allowed to return home on the same day as the surgery takes place. It will normally take about six weeks for your anus to fully heal, but most people are able to resume their normal activities including going to work within one to two weeks after the surgery.
Most people find that the pain they were experiencing from their anal fissure prior to surgery has disappeared within a few days of having their sphincterotomy. A lateral internal sphincterotomy is a simple and widely performed procedure and is highly effective in the treatment of anal fissures. This side effect usually resolves on its own as your anus heals, but there are some cases where it has been persistent.
A lateral internal sphincterotomy is a simple procedure that has proven to be highly successful in the treatment of anal fissures. You will be encouraged to try other treatment methods before surgery, but if these are ineffective, you will be offered this procedure.
