The cost effectiveness of vaginal versus abdominal repair of vesicovaginal fistulae.

INTRODUCTION AND HYPOTHESIS: The objective was to assess the comparative provider costs of vaginal and open abdominal repair of vesicovaginal fistula (VVF) and to determine the most cost-effective means of managing VVF. METHODS: A prospectively acquired database of all women undergoing VVF repair by a single surgeon between 2007 and 2015 was retrospectively reviewed to determine operating time, perioperative complications, inpatient stay and 30-day readmissions. The success and cost of the VVF repair were identified. Statistical analysis was by unpaired t test, Chi-squared test and Mann-Whitney U test. RESULTS: Forty-seven consecutive women of mean age 51 years (range 21-88) undergoing a first attempt at VVF repair at our institution were included; 32(68%) had vaginal repair with Martius fat pad interposition and 15 (32%) had open abdominal repair with omental interposition. There were no perioperative complications or 30-day readmissions in either group. Mean operative time was longer for open abdominal (223.4 min) than vaginal repair (196.9 min). Median inpatient stay was longer for an open abdominal (8 days) than for a vaginal approach (4 days). Successful anatomical closure was achieved in 91% of vaginal and 86% of open abdominal repairs at first attempt, and in 100% after second repair, where required. Mean/median costs for an abdominal repair were significantly higher, at £4,608.69/£4,169.20 than for vaginal repair at £3,381.50/£3,009.24 (P<0.05). CONCLUSIONS: Vesicovaginal fistulae were successfully repaired in 89% of cases at first attempt. The success rate did not differ between approaches. Vaginal repair is significantly more cost-effective than abdominal repair owing to the shorter operative time and length of stay.

Does the Goh classification predict the outcome of vesico-vaginal fistula repair in the developed world?

INTRODUCTION AND HYPOTHESIS: The Goh Vesico-Vaginal Fistula (VVF) classification has prognostic value in VVF in the developing world (predominantly obstetric), with chances of successful closure decreasing from type 1 to type 4. We evaluated the prognostic value of the Goh classification for VVF of the developed world (predominantly iatrogenic). METHODS: A retrospective review was performed of 63 consecutive patients with a mean age of 53 years (range 21-88) undergoing VVF repair under a single surgeon between 2006 and 2014. Demographic data, aetiology, operative data and final outcome (anatomical and functional) were recorded. Fistulae were classified according to Goh's system and outcomes correlated with this classification. RESULTS: Successful closure at first repair was achieved in 90 % of type 1, 83 % of type 2, 100 % of type 3 and 100 % of type 4 fistulae. At second repair success was achieved in 100 % of all fistulae, irrespective of type. Continence post-anatomical closure was achieved in 100 % of type 1, 83 % of type 2, 83 % of type 3 and 75 % of type 4 fistulae. Fistula size and patient age were significant determinants of successful outcome. CONCLUSION: Anatomical closure was obtained in 90 % of VVF of the developed world at first attempt, 100 % overall, and was not affected by the Goh classification. Continence post-anatomical closure of VVF was 94 % overall and deteriorated with increasing Goh classification type. The Goh classification has no prognostic value regarding anatomical closure in VVF of the developed world, but may be useful in determining the risk of post-anatomical closure urinary incontinence. Smaller fistula size and younger patient age are significant determinants of success.
