What is an anal fistula?

An anal fistula is a track between the skin on the outside of the buttock/anal area and the anal canal on the inside. There are many different types of fistulae from relatively simple to a complex branching network of tracks. Some fistulae may involve the muscles responsible for bowel control. Each fistula is individual. The diagram below shows some different types of fistula.

Patient care

Mr Kapil Sahnan, Consultant Surgeon at St Mark’s

Fistulas are as individual as the person that has them. No two patients are the same and will need different surgical procedures and post-operative care.

All information regarding your surgery should have been discussed with you when you saw your doctor in the outpatient clinic. You will be admitted to the day care unit where you will have a further opportunity to ask any questions or address concerns about your surgery.

Most surgeries are now performed as day case operations. You will need to have a responsible adult to take you home and stay with you for the first 24 hours.

Mr Phil Tozer in Theatres at St Mark’s

Following surgery you will be discharged home with analgesics, laxatives and local anaesthetic gel, please use them as instructed.

The telephone number for the Fistula Nurse will be given to you. If you need post-operative advice please call 020 8963 7175

An appointment will be made with the Fistula Nurse for approximately 7 to 14 days post-surgery to review the wound and discuss ongoing self care at home.
