Purpose: The purpose of this study was to report the outcomes with the use of advancement flaps and bioprosthetic grafts for the management of rectovaginal fistulas.

Methods: A retrospective analysis of prospectively collected data was performed for all patients treated with a rectovaginal fistula.

Results: There were 44 patients in the advancement flap group. A mucosal flap repair was performed for 29 patients, and 15 patients had an anodermal flap repair. The mean follow-up was 10 (range, 6-22) months. There were 34 patients in the bioprosthetic repair group. A bioprosthetic interposition graft was used to repair the fistula in 27 patients with a mean follow-up of 12 (range, 6-22) months, and 7 patients had a bioprosthetic plug repair of their fistula with a mean follow-up of 6 (range, 3-12) months. The fistula recurred in 15 patients (34 percent) who were managed by a flap repair, 5 patients (19 percent) who were managed by a bioprosthetic sheet, and 1 patient (14 percent) who was treated with a bioprosthetic plug.

Conclusions: Use of bioprosthetics for the management of rectovaginal fistulas is a new technique, which, based on early experience, seems to yield results equal to advancement flap repair.
