Technique for Minimizing Donor-site Morbidity after Pedicled TRAM-Flap Breast Reconstruction: Outcomes by a Single Surgeon’s Experience

BACKGROUND: Breast reconstruction with pedicled transverse rectus abdominis myocutaneous (TRAM) flap can result in significant abdominal wall donor-site morbidity. We present our technique of transversely dividing the anterior fascia and rectus abdominis combined with reinforcement above the arcuate line for closure of the anterior abdominal wall defect to prevent contour deformities performed by a single senior surgeon and compare these results with those of our prior series. METHODS: We described our new technique of closure of the abdominal wall defect and retrospectively performed the comparison between the results of pedicled TRAM flaps using the new closure technique and those of 420 pedicled TRAM flaps from our 2003 publication in terms of abdominal bulging and hernia. RESULTS: Sixty-seven pedicled TRAM flaps in 65 patients were compared with 420 pedicled TRAM flaps of the 2003 series. The new technique was associated with 5 partial TRAM flap necroses (8%). There was no total flap loss with the new technique. The median follow-up period was 13 months (range, 4–36 months). There were no instances of abdominal hernia and bulge during follow-up in the new series. Compared with the previous 2003 series, the new technique was superior in terms of occurrence of abdominal wall hernia or bulging. CONCLUSIONS: We are still performing pedicled TRAM flap for autologous breast reconstruction. Using the technique of transversely dividing the anterior fascia and rectus abdominis combined with reinforcement above the arcuate line can reduce the occurrence of abdominal bulging and hernia.
