Abstract

Transvaginal (TV) repair, featuring its feasibility, effectiveness, safety, and technically less demandingness, is one of the surgical approaches for management of rectovaginal fistula (RVF). However, there are limited numbers of publications available on the transvaginal approach for RVF repair. To this end, the purpose of this study is to evaluate the preliminary outcomes of the transvaginal approach performed by the team, and to further assess its feasibility, safety and effectiveness in the management of RVF. A retrospective analysis was conducted at a single institution. Patients with RVF who had undergone three transvaginal surgical techniques, i.e. transvaginal fistulectomy and stratified suture, transvaginal flip and ligation fistula tract and transvaginal fistula stapled closure were included. Besides, the demographics, operative data, postoperative complications and follow-up outcomes of the patients were collected prospectively. A total of 49 female patients (mean age, 35.76 ± 13.97years) underwent transvaginal approach, 42 of which were followed up with a median follow-up of 26months (range 3-82months), and 29 had closure of the fistula (successful closure rate of 59.1%). The successful closure rates were only significantly different between previous repair times (p = 0.031), and several minor complications including postoperative pain (n = 3), constipation (n = 1), and lower urinary tract infection (n = 1) were observed. Symptomatic improvement was reported in all patients with failed closure. Transvaginal approach for RVF repair is effective, safe, and feasible, and is therefore considered an alternative to transrectal advancement flap for low and mid-level traumatic RVF with normal sphincter function. With the advantage of better surgical access, transvaginal approach is recognized as the initial choice for the surgical repair of RVF.
