In our opinion, this procedure is safe and its results are promising in terms of clinical outcome and medium- to long-term quality of life.

Patients with inguinal hernia present a wide variety of symptoms, and these are not restricted to the inguinal area. It is important to be aware of this fact to convey accurate information to the patient, especially with regard to postoperative expectations.

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.
