INTRODUCTION The aim of this study was to evaluate the long-term outcome and durability of both autologous and implant-assisted latissimus dorsi reconstruction in a district general hospital over a 10-year follow-up period. METHODS A prospective cohort study was carried out using a detailed database of all latissimus dorsi flap reconstructions performed by a single consultant surgeon between 2003 and 2013 at the Royal United Hospital, Bath. The long-term outcome following reconstruction was assessed by analysing all episodes of ‘reconstruction-specific’ operations required from 6 months after the initial surgery. RESULTS The study included 110 patients with latissimus dorsi flap reconstructions, 21 autologous and 95 implant-assisted. Radiotherapy was given to 27 patients with reconstructed flaps. Mean follow-up was 69 months. Further reconstruction-specific surgery was needed in 27 (23%) cases, with 5 of these being post-radiotherapy flaps. Implant-related surgery was the most common reason for further surgery. Complications of the implant itself made up 52% of these cases, chronic sepsis being the most common. The rate of symptomatic capsular contracture requiring further surgery was 4.2%. Of these, one of four patients had undergone radiotherapy. DISCUSSION In our institution, latissimus dorsi reconstruction is durable and safe over the long term, with limited need for further substantial intervention to maintain a good outcome from the initial reconstruction. Autologous flaps were less likely to require further surgery over the long term compared with implant-based reconstructions. The low rate of symptomatic capsular contracture may be due to the protective mechanism provided by the extended harvest flap used.
