Experiences with an Extraperitoneal Transvesicoscopic Repair of a Vesicovaginal Fistula

Purpose A vesicovaginal fistula (VVF) is a debilitating condition for women in terms of both its personal and social impacts. A reported transperitoneal laparoscopic approach to treatment has some limitations such as risk of intra-peritoneal organ injury and unnecessary bladder dissection. We here report on our experiences with an extraperitoneal transvesicoscopic approach to a VVF repair, which overcomes these drawbacks. Materials and Methods Seven VVF patients were treated using the transvesicoscopic approach. Under general anesthesia, patients were placed in the dorsal lithotomy position. The VVF orifice was obstructed via the vaginal canal using a Foley catheter. The bladder was then filled with normal saline under cystoscopic inspection, and a 5 mm trocar was inserted into it at the suprapubic area. The bladder wall was next fixed to the anterior abdominal wall. Thereafter, two 3 mm ports were punctured at the interspinous skin crease allowing the fistula margin to be cut and sutured in layers. Results Six of the study subjects in whom we attempted a transvesicoscopic repair of VVF had undergone a hysterectomy due to myoma and one had an intraabdominal abscess removal with Behcet's disease. One myoma patient who had a preexisting vesicoperitoneal fistula was converted to an open transabdominal VVF repair. The mean age of the 6 remaining patients was 46.0 ± 7.2 years (range, 35-57). The mean operation time was 273 ± 40.6 minutes (range, 223-323). There was no instances of significant pain or other immediate complications. Five patients showed no recurrence of the fistula during the follow-up period (8.7±5.1 months). Conclusion A transvesicoscopic approach is an effective modality for the repair of a VVF that is more minimally invasive and has a lower morbidity than a transabdominal procedure.
