Reconstruction of complex rectovaginal fistula is challenging, and it has a high recurrence rate. Traditional reconstruction included a local flap or a myocutaneous flap reconstruction, which is either difficult in radiated cases or that the flap is too thick for flap inset and requires multiple times of revision. Here we report successful rectovaginal fistula repair using a pedicled medial circumflex femoral artery perforator flap (MCFAP). A retrospective chart review was done to collect the information of this 63-year-old female patient who had rectovaginal fistula (RVF) resulting from concurrent radiochemotherapy for cervical cancer. She received direct repair of the RVF, but it recurred. We applied a pedicle perforator flap to successfully repair the defect. The fistula was repaired by separating the posterior vaginal wall from the anterior rectal wall. The anterior wall of the rectum was primarily repaired, leaving a defect of 4 × 5 cm in the posterior vaginal wall. A pedicled MCFAP flap was harvested from her right medial thigh and transferred via a subcutaneous tunnel for reconstruction of the posterior vaginal wall defect. The postoperative course was uneventful. Postoperative gastrointestinal series showed no more RVF, and her colostomy was taken down one year after the reconstruction. This first experience suggests that a pedicle perforator flap can be used successfully for reconstruction of a rectovaginal fistula.
