An anal fistula is an abnormal communication from the bowel on the inside and the skin around the back passage. The cause discharge (mucous and blood) and can result in a painful abscess. They can be quite difficult to treat and this almost always involves a simple operation; either to cut the fissure out or place a small plastic drain (seton) which can settled the symptoms down.
If you want to discuss treatment then please contact my secretary to book an appointment.
