[Application of acellular allograft dermal tissue patch in the repair of transvaginal rectovaginal fistula].

OBJECTIVE

To investigate the clinical effect of acellular allograft dermal tissue patch used in transvaginal rectovaginal fistula repair.

METHODS

From Jan. 2008 to Dec. 2011, 22 patients with rectovaginal fistula undergoing treatment in Chinese People's Liberation Army General Hospital were studied retrospectively. Twelve patients treated by tissue patch were classified into study group matched with 10 patients with general surgery as controls.

RESULTS

In study group, 11 patients were successfully repaired by their first surgery;one patient was successfully fixed by the second surgery. The successful rate of first operation was 11/12 in study group and 4/5 in recurrent transvaginal rectovaginal fistula. In control group, 7 patients were fixed successfully in their first surgeries, the successful rate of first surgery was 7/10. Two primary patients and 1 recurrent patient were successfully fixed by their second surgeries. All of the patients were followed up for (9.0 ± 2.0) months, and no recurrence diseases were observed.

CONCLUSION

The transvaginal rectovaginal fistula fixed using acellular allograft dermal tissue patch could get less trauma and higher cure rate.
