BACKGROUND: The nonhealing perineal wound is often a catastrophic complication after aggressive surgical extirpation of pelvic malignancies. METHODS: Eleven patients underwent perineal reconstruction using an inferiorly based transpelvic transverse rectus abdominal myocutaneous (TRAM) flap for large nonhealing postsurgical perineal wounds. After debridement of the perineum, the rectus muscles and their skin islands were mobilized, preserving their inferior epigastric blood supply. The flap was then taken through the midline abdominal incision transpelvically into the perineal defect. The study population was composed of three men and eight women ranging in age from 43 to 76 years (mean 59). The primary diagnosis was recurrent carcinoma of the rectum or anus (n = 5), recurrent squamous cell carcinoma of the vulva or cervix (n = 4), and recurrent sacral chordoma (n = 2). All patients had received adjuvant radiation therapy and all patients had undergone one to four previous attempts at perineal closure. The perineal defect ranged in size from 72 cm2 to 1,250 cm2 (mean 337). RESULTS: There were no perioperative deaths. Ten of the 11 patients (91%) had primary wound healing of the TRAM flap, perineal wound, and donor site. One patient with recurrent chordoma developed recurrent tumor at the suture line 4 months postoperatively. CONCLUSIONS: The inferiorly based transpelvic TRAM flap is a safe and effective reconstructive technique for recalcitrant nonhealing perineal wounds after extirpation of pelvic malignancies.
