Abstract
Background Autologous flaps may have superior outcomes when compared to implant breast reconstruction in patients with obesity. To date, no published review has illustrated the superiority of autologous to implant-based reconstruction in this study group in terms of aesthetics outcomes and surgical complications.
Methods A systematic search was conducted on PubMed, Cochrane, Google Scholar, and Embase from inception to December 31, 2020. Studies comparing the outcomes (patient satisfaction and complications) of autologous versus implant-based reconstruction in patients with BMI > 30 were selected.
Results The search yielded 1633 articles, of which 76 were assessed in full text. A total of 12 articles fit inclusion for qualitative review; of them, 7 were meta-analyzed. Autologous reconstruction had a lower incidence of infection (OR 0.74 [95% CI 0.59, 0.92]), hematoma/seroma formation (OR 0.34 [95% CI 0.23, 0.49]), and reconstructive failure (OR 0.47 [95% CI 0.36, 0.62]), but not skin necrosis (OR 0.95 [95% CI 0.73, 1.25]) or wound dehiscence (OR 1.03 [95% CI 0.72, 1.49]) when compared to implant-based reconstruction. Deep vein thrombosis (DVT) and pulmonary embolism occurred more frequently with autologous versus alloplastic reconstruction (OR 2.21 [95% CI 1.09, 4.49] for DVT and OR 2.49 [95% CI 1.13, 5.48] for PE). BREASTQ scores were higher for the autologous breast reconstruction when compared to implant-based group, but failed to reach significance (p value >0.05).
Conclusion The current evidence in the literature suggests that autologous breast reconstruction has lower surgical complication rate when compared to implant-based reconstruction at the expense of higher risk of thrombotic complications for patients with BMI > 30.
