The management of abdominal contour defects following TRAM flap breast reconstruction

Abstract

Background: Incisional hernia can develop following breast reconstruction with abdominal tissue regardless of technique, and the management is often challenging. Objectives: The authors characterize hernias following transverse rectus abdominis musculocutaneous (TRAM) flap procedures and evaluate outcomes of different strategies for repair. Methods: All patients who underwent repair of a TRAM-related hernia or bulge between 2003 and 2011 at a single institution were retrospectively reviewed. A minimum of 2 years' follow-up was required for inclusion in this series. Outcomes of different techniques for repair were compared and risk factors for hernia recurrence identified. Results: Forty-three patients underwent repair of a TRAM-related hernia or bulge, most often with mesh (74.4%, n = 32). At a mean overall follow-up of 5.2 years, 9 patients (20.9%) developed recurrent hernia or bulge. Compared to primary suture closure, the use of mesh was protective against recurrence (odds ratio, 0.05; 95% confidence interval, 0.00-0.65; P = .02), with the best results observed with fascial closure and underlay mesh reinforcement. Conclusions: Incisional hernia following TRAM flap breast reconstruction can be a challenging problem. Attention to surgical technique and the use of mesh minimize the risk of recurrence. © 2013 The American Society for Aesthetic Plastic Surgery, Inc.
