Robotic-Assisted Laparoscopic Repair of Iatrogenic Vesico-Vaginal Fistula

Study Objective

This video highlights the principles of robotic assisted laparoscopic repair of iatrogenic vesico-vaginal fistula

Design

Surgical video presentation.

Setting

Academic tertiary care center.

Patients or Participants

We present 2 cases of iatrogenic vesico-vaginal fistula repaired robotically. Case 1 is a 49-year-old patient with a vesico-vaginal fistula after an open supracervical hysterectomy with incidental cystotomy and repair. Case 2 is a 61-year-old patient who was referred for management of a supra-trigonal vesico-vaginal fistula as a complication of vaginal hysterectomy.

Interventions

Case 1 started with cystoscopy and placement of ureteral stents. The peritoneum above the vaginal cuff was incised and an anterior colpotomy was created. The bladder was dissected until the fistula was identified and the injured area was 4 cm away from the colpotomy. The fistulous margins where dissected. The bladder mucosa was repaired in 2 layers in a running fashion. The bladder was retrogradely filled, confirming the repair was watertight. The colpotomy was closed in 2 layers. The repair was reinforced with omental interposition. For case 2, a stent was placed through the vaginal fistulous opening. The stent was identified transvesically with cystoscopy. Bilateral ureteral stents were placed. Similar steps from case 1 were carried out. Cystoscopy was performed confirming an adequate repair. Bilateral ureteral stents were removed. A Foley catheter was inserted to remain in place for 3 weeks.

Measurements and Main Results

Both patients were discharged on post-operative day 1. The patient in case 1 had a voiding cystogram showing no evidence of residual or recurrent fistula on post-operative week 3, and urine leakage was resolved. The patient in case 2 is scheduled for follow up on post-operative week 3.

Conclusion

Robotic assisted repair offers optimal surgical exposure and is ideal for supra-trigonal and complex vesico-vaginal fistulas, affording good outcomes for patients.
