Video-Assisted Anal Fistula Treatment for Treatment of Complex Cryptoglandular Anal Fistulas with 2 Years Follow-Up Period: Our Experience.

Abstract

Aim: The aim of this prospective, nonrandomized, observational study was to present our results in operative treatment of complex anal fistulas using video-assisted anal fistula treatment (VAAFT) procedure with a curative intent in 2 years follow-up period. Materials and Methods: Between March 2016 and March 2018, 73 patients underwent the VAAFT procedure. Postoperative follow-up was 2 years, up to March 2020. Only patients with complex cryptoglandular anal fistulas were included. All patients were referred for magnetic resonance imaging of the pelvis. Fecal incontinence severity index score was used to assess any continence disturbance prior operation and postoperatively. Result: Primary healing occurred in 52 cases (71.23%) after first operation. From 21 patients who had recurrence or who had persisting disease, 16 patients accepted reoperation with second VAAFT procedure and additionally 10 patients achieved healing. From a total number of 73 patients who were included in study healing ultimately occurred in 62 cases (84.93%). In the first operation internal opening was identified in 47 cases (64.38%) and was closed with mattress suture, rectal advancement flap or ligation of intersphincteric fistula tract technique depending on its extent and type of fistula. Median primary healing rate was 6 weeks. There were no serious intra- or postoperative complications. None of the patients reported any type of continence disturbance. Discussion: VAAFT has been shown to offer good rates of healing, low morbidities, possibilities of multiple attempts in case of first failure and this series adds to the literature.
