Anal fistula surgery
Surgery to remove anal fistulas
Our gastroenterology surgeons specialise in treating anal fistulas
About
Anal fistulas are small tunnels that can develop between the end of your rectum and the skin near your anus. Fistulas can get better on their own. But in other cases, surgery may be the only way to get rid of them.
We specialise in various techniques for treating anal fistulas, including:
- Fistulotomy. The fistula is cut open and laid out flat, but only if there's no risk to the anal sphincter.
- Seton technique. This involves inserting a surgical thread through the fistula to make a loop and bring it to the surface.
- Advancement flap procedure. Normally carried out after a fistulotomy to cover a fistula opening to prevent infections.
- Bioprosthetic plug. This involves blocking the internal opening in a fistula to let it heal gradually. The outside opening can then be drained of pus.

What happens icon plus
Your consultant's preferred surgical technique will depend on the type of fistula you have, its location and whether it crosses your anal sphincters. Whichever one they choose, you'll most likely be under general anaesthetic, which means you'll be asleep. -
How to prepare icon plus
You'll most likely be asked to attend a pre-procedure assessment, where your consultant or specialist nurse will explain the procedure. They'll also answer any questions you might have, and inform you of any risks and side effects involved. -
Afterwards icon plus
Depending on the nature of your fistula, you may be able to go home on the day of your surgery. Otherwise, we'll transfer you to our recovery ward where we'll care for you until you're discharged. Your consultant will let you know when you can get back to your usual routine, including work or exercise. Fistula surgery wounds can take several weeks to heal, and you may experience a little discharge and bleeding from the wound. Your consultant or specialist nurse will explain what else to expect during your post-op period.
