Functional recovery after bilateral extended autologous latissimus dorsi breast reconstruction : a prospective observational study

Background: The impact of unilateral extended autologous latissimus dorsi (EALD) flap harvest and axillary surgery on shoulder function has been well described, but the impact of bilateral EALD flap harvest has not been clearly defined nor is it clear whether reconstructions should be synchronous or staged. Methods: In this prospective observational study, patients undergoing bilateral EALD breast reconstruction (February 2003–December 2009) completed the disability, arm, shoulder and hand (DASH) questionnaire preoperatively and at five post-operative timepoints. Intensive shoulder physiotherapy was offered to those whose DASH score was >30 at 6 weeks or >20 at 12 weeks post-operatively. Results: Sixty patients underwent bilateral EALD flap breast reconstruction (51 synchronous, 9 metachronous). Patients with pre-existing shoulder pathology (n = 1) and those who failed to return any post-operative DASH questionnaire (n = 10) were excluded from initial DASH analysis. However, these eleven patients were included in a separate analysis as an intention-to-treat analysis. Statistical analysis was performed using non-parametric, Friedman test and multiple comparison model. Forty-nine patients’ DASH scores were analysed. DASH score initially increased after surgery and then returned to functionally normal within 3–6 months (median DASH: preoperative = 1 vs 6 weeks post-operation = 26, p = <0.001; vs 3 months = 19, p = <0.001; vs 6 months = 13, p = <0.001); thereafter, the scores remained less than 12 (p =
