Excision and Advancement Flap

When there is a high fistula, the primary tract across the sphincters is excised and an advancement flap is performed. This procedure consists of a conventional fistulectomy, an opening of the intersphinc-teric space through a partial excision of the internal sphincter, occlusion of the former primary orifice of the fistula and an advancement mucosal flap [67,68].
