Lateral Internal Sphincterotomy

A lateral internal sphincterotomy is considered the gold standard for treating chronic anal fissures.

Lateral internal sphincterotomy surgery helps an anal fissure to heal and relieves its symptoms such as severe pain and bleeding especially after a bowel movement.

The operation is performed under general anaesthetic and involves cutting your anal sphincter. The anal sphincter is a circular group of muscles that control your bowel movements. Releasing the sphincterotomy muscle of your anus, reduces tension and allows your anal fissure to heal.

A lateral sphincterotomy takes about 15 minutes. It has a very high success rate. However, incontinence can be a complication after this procedure.

As a lateral internal sphincterotomy is a day case procedure, you can go home the same day once the effects of the anaesthetic have worn off. You will need to arrange for someone to drive you home, as you should not drive for 24 hours after a general anaesthetic.

You can expect to have some discomfort after the operation. Simple pain relief will help. It is recommended that you have a bath the day after your operation to help soak away any dressing and to keep your anus area clean. You may have a small amount of bleeding in the bath.

You may also have a little mucous discharge from your back passage for the first few days. A small pad or panty liner will prevent staining your underwear.

Yes, a sphincterotomy is permanent. It is surgery to permanently release the sphincter muscle of your anus.

The recovery time and process will vary from patient to patient but you can expect to return to work after just a few days.

You should try to take a bath or shower after every time you open your bowels in the first few days after your lateral internal sphincterotomy operation. After that you can wipe your anal area using damp cotton wool.

There may be a little blood with your poo or on the toilet paper for seven to ten days afterwards.

You will find it more comfortable to have bowel movements if your poo is soft. Drink plenty of fluids and eat a high-fibre diet with fruit, vegetables, pulses and bran. You may be given a laxative to take home that makes your stools softer.
