Abstract

A prospective study was carried out on 88 patients with rectovaginal fistulae to evaluate the value of two sphincter-saving techniques: primary occlusion of the intraanal ostium and endorectal advancement flap (n = 37) or transperineal repair with levator interposition (n = 34). Causes were Crohn's disease 35, obstetric injury 31, proctological-gynecological operation 11, cryptoglandular 11. Perineal group: 11 patients underwent concomitant anterior sphincter plication. Crohn group (n = 35): endorectal advancement flap was performed in 8 patients only, and 10 with intra- or supraanal stenosis were treated by transperineal approach, 12 (34%) with extended perianal fistula complaints required primary proctectomy, and operative therapy was not possible in 5 with persistent rectal inflammation. No deaths occurred. Postoperatively 12 cases (17%) of suture leakage occurred (flap group (FG): 16.2%, transperineal group (TPG): 17.6%). Persistent or recurrent fistula occurred in 8 patients (11%), 5.4% FG, 17.6% TPG. Disturbance of continence was observed in one patient after endorectal approach. Postoperatively there were no significant changes in the resting anal pressure and maximum voluntary contraction pressure. A complete primary healing with no further recurrence (follow-up 3 months to 9.5 years) was noted in 78.4% FG and 64.7% TPG. One patient with postoperative incontinence after the endorectal flap, had undergone anterior levator plication with perineal body reconstruction.

CONCLUSIONS:

Endorectal advancement flap allows preservation of the sphincter and is an effective method for repair of rectovaginal fistulae. The endorectal advancement flap proved to result in a better primary healing rate with 85% than the mucosal advancement flap with 65%. Perineal procedures are indicated in selected patients with simultaneous sphincter plication and in Crohn's fistulae associated to intra- or supraanal stenosis.
