Transvaginal repair of a rectovaginal fistula caused by transvaginal mesh prolapse surgery.

Abstract

<h4>Introduction</h4>Transvaginal mesh surgery can cause mesh complications including rare rectovaginal fistula. We report a case of a rectovaginal fistula treated transvaginally without colostomy.<h4>Case presentation</h4>A 57-year-old female was referred to us due to post-hysterectomy prolapse and had transvaginal mesh surgery. She underwent transvaginal hysterectomy because of uterine prolapse at age 33 and had taken steroids to treat pemphigus. Two years later, she developed vaginal bleeding and discharge. Transvaginal mesh removal was planned to treat vaginal mesh exposure, but immediately before the operation digital rectal examination revealed rectovaginal fistula. Mesh removal and fistula closure were performed transvaginally without colostomy. Three years of follow-up showed no recurrence of mesh exposure, fistula, or prolapse.<h4>Conclusion</h4>Rectovaginal fistula following mesh surgery may be treated transvaginally without colostomy if infection is minimal. To evaluate mesh exposure on the posterior vaginal wall, rectal examination should be done along with vaginal examination.
