Introduction And Hypothesis:
Vesicovaginal fistula (VVF) is an abnormal communication between the bladder and the vagina. Complex fistulae include those after failed repair attempts, radiotherapy, measuring ≥ 2 cm, located in the trigone, or with concomitant ureteric strictures or fistulae. We aimed to describe a technique for the robotic repair of a complex VVF using a vaginal cuff flap.
Methods:
A 56-year-old woman with a history of ovarian debulking surgery and radiotherapy underwent repair for VVF and rectovaginal fistula. In lithotomy, cystoscopy was performed for fistulous tract cannulation. Port placement, extensive adhesiolysis, and robot docking followed. The vaginal apex was dissected, the VVF excised, and the bladder closed. The rectum was separated from the posterior vaginal wall, the rectovaginal fistula excised, and the rectum closed. A vaginal cuff flap was harvested and interposed between the bladder and the vagina.
Results:
Operative time was 9 h, estimated blood loss was 300 cc, and no intraoperative complications occurred. The patient was discharged on postoperative day 8. Further management included 37 sessions in a hyperbaric chamber and a transvesical endoluminal bladder closure 10 months after the initial surgery. Follow-up at 30 months shows no fistula recurrence.
Conclusions:
Vaginal cuff flaps represent a feasible interposition tissue in patients with hysterectomy for managing complex VVF in the case of omentum unavailability.
