Understanding Lateral Sphincterotomy

Lateral sphincterotomy, also known as Anal sphincterotomy, is a surgery that involves cutting or stretching the hypertrophied internal sphincter (anal sphincter).

The Lateral sphincter is a bundle of muscles at the digestive tract’s end that connects to the rectum. This circular muscle group controls bowel movements. When an anal fissure forms, it can cause bleeding and, in some cases, pain. Surgery is recommended if all other treatments have been tried without success. The internal anal sphincter muscle is slightly incised during the treatment to release tension and promotes successful healing of the fissure.

How Does the Lateral Internal Sphincterotomy Procedure Work?

To reach the muscle around your anal canal called the anal sphincter, the surgeon will make a small cut in the skin of your anal canal. This muscle controls how the anus opens and closes. The surgeon will then make a small cut in the sphincter to loosen it, prevent spasms, and help it heal naturally.

Lateral internal sphincterotomy is a day-case operation, which means you can go home the same day once the anaesthesia goes off. It would help if you made plans for someone to drive you home because you should not drive for 24 hours following a general anaesthetic.

After the surgery, you may experience some soreness, which can be relieved with simple pain medication. It’s recommended to take a bath the day after the surgery to soak up any dressings and keep your anus clean. You may see a small amount of bleeding in the bath. You might also have a small amount of mucus flow from your back passage for the first few days. To avoid staining your pants, you can use a small pad or panty liner.

Frequently Asked Questions

01.What are the potential Lateral Internal Sphincterotomy complications?

Surgery to fix an issue with the muscle controlling the anal sphincter can help many people, but there are risks. After the surgery, bleeding or pus collection may occur. Some may experience temporary trouble controlling bowel movements.

02. What is the typical Lateral Internal Sphincterotomy healing time?

Many people experience relief from the pain of their anal fissures within a few days after the surgery. However, it may take around 6 weeks for the anus to fully heal.

03. What are the things to avoid following a sphincterotomy?

After a sphincterotomy, it’s important to avoid doing any strenuous activities for at least a week. You should take sitz baths (sitting in warm water for 15-20 minutes) three times a day and after every bowel movement in the first few days. It’s normal to experience some bleeding, discharge, or itching during your recovery, so there’s no need to worry about it.

04. What are the Lateral Internal Sphincterotomy steps involved in the procedure?

  • Initial dissection.
  • Division of internal sphincter.
  • Closure of incision.
  • Closed lateral internal sphincterotomy.

05. How much pain can I expect after surgery?

This is a very common concern. While there will be some discomfort, the pain after surgery is usually much less severe than the pain you were experiencing from the anal fissure. Your doctor will prescribe medication to help manage any pain you experience.

06. What kind of anaesthesia will be used during the surgery?

The operation is usually performed under a general anaesthetic, but various anaesthetic techniques are also possible.

07. Will I be able to control my bowel movements after surgery?

Incontinence is a rare complication of sphincterotomy, and most people do not experience any problems with bowel control after surgery.

08. What dietary restrictions will I need to follow after surgery?

Your doctor will likely recommend that you eat a high-fibre diet and drink plenty of fluids to help keep your stools soft. This will help to make bowel movements less painful.
