Objective: This is to introduce a new method for repair of rectovaginal fistual.
Methods: On the basis of an anatomical study a new type of the pudendal-thigh flap pedicled on the obturator artery has been designed to repair rectovaginal fistual.
Results: 4 patients were treated with this method. All flaps survived and the fistula between vagina and rectum was closed primarily.
Conclusions: The advantages of the pudendal-thigh flap pedicled on the obturator artery include: 1. Good blood supply; 2. Relative thin and hairless; 3. Perfect hiding of the donor site. We think that it is one of the best methods of rectovaginal fistula repair.
