Abstract

Background: Nipple-sparing mastectomy (NSM) use is increasing. We investigated the relationships between body mass index (BMI), operative time (OT), and ischemic complications. Methods: A single center, retrospective review was performed of NSMs from 2006 to 2018. Analysis included descriptive statistics, Wilcoxon rank-sum test and logistic regression. Results: Among 294 patients, 510 breast reconstructions were performed (216 bilateral). Median OTs in the prosthetic-based (266 patients, 90.5%) and autologous tissue groups (28 patients, 9.5%) were 266 and 529 min, respectively. Median OTs ranged from 236 to 358 min for those with BMI <20 and ≥ 40, respectively. Increasing BMI correlated with OT (r = 0.33, p < 0.001) and was associated with slightly higher odds of major NAC ischemic complications (OR = 1.09, p = 0.02). Conclusion: Higher BMI is associated with up to 50% longer OT, but is not a contraindication to NSM with reconstruction. Surgeons should recognize increased time and resource utilization.
