What is Anal Fistula?

An anal fistula is an abnormal connection between the surface of the anal canal and the perianal skin. It is normally formed after a perianal abscess bursts or when an abscess is not treated properly. Anal fistula requires surgery most of the time and it can rarely heal by itself.

The main options include procedure that involves cutting open the whole length of the fistula, so it heals into a flat scar. A further common procedure is called seton insertion, where a piece of surgical thread, called seton, is inserted in the fistula and left there for several weeks to help it heal before a further procedure is carried out. There are also several non-invasive surgical treatments available. However, all the procedures have different benefits and risks. For complex fistula patients may need several procedures before having the problems resolved.

Mr Leo has a wide and long experience with both traditional approaches as well as newer non-invasive procedures such as VAAFT (endoscopic treatments), laser (FiLaC), radiofrequency (Rafaelo), use of plugs, glues and meshes. Either procedure is usually chosen with the patient, considering the type and complexity of the fistula, and considering patients’ needs.  Most of the procedure can anyway be carried out in a day surgery regime and usually under general anaesthesia.
