RESUMEN
BACKGROUND: Prepectoral (PP) breast reconstruction is now commonly performed and minimizes dissection of the pectoralis major muscle. Data are lacking comparing the immediate postoperative recovery of these patients as compared with traditional subpectoral (SP) breast reconstruction. METHODS: From December 2015 to February 2017, 73 patients underwent PP prosthetic-based reconstruction at a single academic institution. PP cases were matched 1:1, by age and stage, to patients undergoing traditional SP reconstruction. Analysis of postoperative pain (visual analog scale) and opioid use (oral morphine equivalents, OME), was performed with both bi- and multivariate analyses. Additional outcomes explored included length of stay (LOS) and reconstructive intervention by plane of prosthetic reconstruction. RESULTS: A total of 146 patients were included in the final cohort. PP reconstruction was associated with higher rates of direct-to-implant reconstruction (84.9% vs. 34.3%, p <0.001) and higher rates of initial prosthetic fill (401.53â¯mL vs. 280.88â¯mL, p<0.001). Patients undergoing PP reconstruction had significantly reduced postoperative pain (4.29â¯vs. 5.44, p<0.001) and in-hospital opioid use (62.63â¯mg OME vs. 98.84â¯mg OME, pâ¯=â¯0.03) compared with SP patients. This result remained in multivariate analysis for both pain (3.94â¯vs. 5.25, p<0.001) and opioid use (17.14â¯mg OME vs. 63.03â¯mg OME, pâ¯=â¯0.03). Additionally, patients undergoing PP reconstruction had significantly reduced overall LOS on multivariate analysis (21.36â¯vs. 26.28 h, pâ¯=â¯0.02). CONCLUSION: Following mastectomy, PP breast reconstruction results in significantly reduced pain, opioid use, and hospital LOS compared with SP reconstruction.
