Robotic Vesicovaginal Fistula Repair.

STUDY

OBJECTIVE

To illustrate a technique of robotic vesicovaginal fistula repair in a patient with a previous history of pelvic radiation therapy and multiple abdominal surgeries.

DESIGN

Stepwise demonstration of the technique with narrated video footage.

SETTING

This 59-year-old woman presented with vesicovaginal fistula. She had a history of rectosigmoidectomy followed by pelvic radiotherapy for stage III colon cancer 23 years earlier and subsequent robotic hysterectomy, bilateral salpingo-oophorectomy, and omentectomy with bilateral pelvic and para-aortic lymphadenectomy for stage II mixed cell endometrial carcinoma, which required surgical reintervention because of a pelvic hematoma and complete vaginal cuff dehiscence.

INTERVENTIONS: We performed a robotic approach to vesicovaginal fistula with several key steps to repair the fistula and maintain the integrity of the abdominopelvic structures: (1) careful bowel adhesiolysis involving multiple segments of the intestine to the abdominal and pelvic peritoneum; (2) cystotomy with vaginal probe guidance; (3) fistulectomy by monopolar scissors after ureteral orifice visualization; (4) dissection of the retropubic space of Retzius, relieving bladder tension; (5) transverse sutures to coapt the raw surfaces on the vaginal side and the bladder in 2 layers with minimal tension; and (6) transurethral instillation of methylene blue into the bladder.

CONCLUSIONS

Traditionally, patients with vesicovaginal fistula after pelvic radiation therapy and multiple abdominal surgeries are managed by laparotomy. This video demonstrates a feasible robotic approach to vesicovaginal fistula repair, with superior imaging affording 3-dimensional visualization and stabilization of instruments, allowing wrist-like movements.
