Abstract

Surgical treatment of high perianal fistulas, which affect a significant proportion of the sphincter apparatus, is difficult and associated
with considerable risk of impaired anal continence. The diversity of approaches proposed for the treatment of complex
perianal fistulas reflects the fact that no method has yet been shown to be fully satisfactory. We believe the successful treatment
of this condition is directly proportional to the amount of fibrous tissue that can be removed. We used a kit of small curettes, of
different thicknesses and sizes, incorporating spicules that enable the physician to remove fibrous tissue from the fistula tract. The
small size and varying thicknesses of the curettes enable them to mold to the curves of the fistula tract and to remove tissue by
de-roofing from the shallowest to the deepest layers, thus excising the entire fibrous tract. The tract is then sealed using autologous
fibrin, applied through a catheter, with the help of a monitor indicating the amount of product remaining at all times. Finally, the
internal orifice is closed by simple suturing.
