Surgery for Anal Fistula

Surgery for Anal Fistula

From £2,311.00

An anal fistula is an abnormal connection between the lining on the inside of your anal canal (back passage) and the skin near your anus. Most anal fistulas are caused by an abscess (a collection of pus) that has developed in your anal canal. The pus can drain away onto your skin on its own or by an operation. A fistula happens when the track, made by the pus on the way to the surface of your skin, stays open.

Description

The operation is usually performed under a general anaesthetic and usually takes 15 to 30 minutes.

To lessen the risk of bowel incontinence (when you pass a bowel movement without wanting to) your treatment may involve several operations over a number of months.

The type of surgery you need will depend on where the fistula is (see figure 1).
•If the fistula is below or crosses the lower part of the sphincter muscles, your surgeon will cut the fistula open to your skin and leave the wound open so that it can heal with healthy tissue.
•If the fistula has branches that pass through the upper part of the sphincter muscles, your surgeon may place a special stitch (called a seton stitch) in the fistula to allow pus to drain easily.
•The fistula may be suitable for treatment with a plug made from pig-bowel tissue. Your surgeon will not need to make a cut in the sphincter muscle.
•If the fistula reaches above your sphincter muscles, you may need to have a temporary colostomy (your large bowel opening onto your skin). However, this is not common.
