[Surgical management of anal fistula].

Unlabelled: Anal fistula has been known since the beginning of medical history and is defined as a duct of fibrous infected walls that runs from anal crypt to skin or rectal lumen. Internal orifice is called primary or internal, while cutaneous orifice is referred to as secondary or external. Several techniques have been developed for surgical management of anal fistula, including fistulotomy, fistulectomy with or without sphincter repair, placement of sedal cutting or seton drainage, endorectal advancement flap, and fibrin glue, among others.
