Postsurgical Outcomes with Meshes for Two-stage Prosthetic Breast Reconstruction in 20,817 Patients.

Abstract

Patients who underwent breast reconstruction with and without ADM were identified from the National Surgical Quality Improvement Program database utilizing CPT codes. Covariates included patient demographics, preoperative comorbidities, and operative characteristics, while outcomes of interest were postoperative infection and reoperation. Univariate and multivariate analyses were performed to identify predictors of adverse outcomes. There were 8334 patients in the ADM cohort and 12,451 patients who underwent tissue expander breast reconstruction without ADM. There were significantly fewer reoperations in the non-ADM cohort (5.4%) compared to the ADM cohort (7.7%) (P < 0.0001), with infection and hematoma as the most common etiologies in both cohorts. Surgical infections were also more prevalent in the ADM cohort (4.7%) compared with the non-ADM cohort (3.6%) (P < 0.0001). Univariate and multivariate analysis of the tissue expander breast reconstruction cohort revealed race, obesity, hypertension, smoking status, albumin, and operative time as predictive for infection risk, while race, obesity, hypertension, smoking, albumin, operative time, and age were significant for reoperation. Our study of 20,817 patients revealed significantly higher risk of infection and reoperation in patients who underwent breast reconstruction utilizing ADM versus without ADM. Patients considering ADM for breast reconstruction should engage in discussion with their surgeon about complications, aesthetics, and cost.
