Functional sequelae following bilateral mastectomy and immediate reconstruction with latissimus dorsi flap:...

Arm morbidity following unilateral Latissimus Dorsi (LD) flap harvest is controversial and bilateral harvest is considered potentially disabling. Arm and shoulder disability was investigated in patients undergoing bilateral mastectomy and immediate LD flap reconstruction. Thirty consecutive bilateral immediate reconstructions with denervated LD flaps, performed between 2005-2009, were retrospectively analyzed. Patients were assessed for arm function by conducting the Disability of Arm, Shoulder and Hand (DASH) test, between 12-51 months after surgery (mean 23 months). Disability scores ranged from 1-100%, with 1-25% being regarded as mild dysfunction, 26-50% as moderate dysfunction, 51-75% as severe dysfunction, and 76-100% as total dysfunction. A statistical analysis was performed using the Fisher exact test and the multivariate linear regression model for variables. The Global Mean Dash score was 14.8%. Twenty-four patients presented a mild functional deficit (< 25%), while six presented a moderate one (< 50%). Five of them presented a score < 40%, while only one patient presented a score of 49.1%. Higher scores were significantly associated (p < 0.001) with major postoperative complications and lower ones with re-innervated LD flaps (p < 0.01). An insignificant functional impairment was noted in most patients, while a moderate-to-severe one was noted only in the group with complications. Greater impairment is observed in the heavy activities. The DASH test is a useful tool in terms of informing patients and helping the surgeon to choose the best surgical option.
