Abstract

Abstract: Immediate breast reconstruction (IBR) has become the most common method for postmastectomy reconstruction. Axillary lymph node dissection is performed for the staging of patients, but the impact of IBR with nodal surgery on postoperative complications remains elusive. The present study aims to investigate the impact of concomitant axillary lymph node surgery on postoperative complications. We conducted a retrospective study of patients who underwent IBR from 2000 to 2014. We recorded and analyzed patient data to determine the association between nodal surgery and postsurgical complications. Univariate and multivariate analyses were utilized to elucidate the risk of a complication given nodal surgery, sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND), and type of incision for nodal access. A total of 986 breast reconstructions were included for analysis. Overall incidence of postoperative complications per breast that received nodal surgery was 35.9% (n = 230/642), compared to 25.6% (n = 88/344) in breasts that did not have concomitant nodal surgery ( P = .001). Nodal surgery was found to increase risk of all complications with an odds ratio of 1.62 ( P = .001). Moreover, complications were significantly higher in patients whose nodes were accessed via mastectomy incision (39.4%) when compared to a separate incision (33.5%). Multivariate analysis showed that nodal sampling through the mastectomy incision is a significant risk factor for seroma, with an odds ratio of 3.60 ( P = .002). We did not observe differences in breast complications in patients who underwent SLNB vs ALND. These factors should be taken into account in the approach to breast reconstruction during lymphadenectomy.
