Robotic repair of vesico-vaginal fistula with perisigmoid fat flap interposition: state of the art for a challenging case?

ABSTRACT

Since its introduction, robotic-assisted operations have established themselves in an increasingly wide range of procedures. We applied this approach as a viable surgical alternative for the management of a complex vesicovaginal fistula. We present the case of a patient with total urinary incontinence due to the formation of a vesicovaginal fistula, following total abdominal hysterectomy. The fistula was located at the vaginal vault and at approximately one cm from the right ureteric orifice. For this specific scenario a robotic approach was chosen over the vaginal-, laparotomic- and laparoscopic repair, as in our view it offered the best possibility to specifically treat the target anatomy with a reduced risk for involvement of the surrounding structures, while maintaining a low morbidity and a quick postoperative recovery.In our video we show how the vesicovaginal fistula can be repaired by interposition of a vascularized flap of perisigmoid fat, in order to reduce the risk of recurrences [Ezzat et al., Repair of giant vesicovaginal fistulas, 181(3)1184-1188, 2009].The postoperative course was uneventful; on postoperative day 1 the patient reported pain of 2/10 on a VAS scale (0 = no pain; 10 = unbearable pain) and was mobilized. She was discharged on postoperative day two with bladder catheter in situ. The successful repair of the fistulous tract was confirmed via retrograde cystogram on postoperative day 10 and the patient was continent immediately after catheter removal. At the six month follow up visit the patient had no complaints.
