Abstract
Perianal fistula usually results from a non-specific infection of the cryptic glands located at the anal dentate line. Identification of the exact course of a perianal fistula and the extent of anal sphincteric complex involvement are of paramount importance, in order to design the therapeutic and interventional approach and achieve the best results without impairment of the anorectal function. Several interventional methods are in use for the surgical treatment of CPF, including fistulotomy, insertion of cutting “seton”, core fistulectomy, ligation of the intersphincteric fistulous track (LIFT), rectal advancement flap, injection of fibrin glue at the fistulous track, insertion of fistulous plug, and obliteration of the fistulous track with the use of Laser. In clinical practice a combination of the aforementioned methods can be used, in particular for the complex-high or recurrent fistulae.
