Does Immediate Tissue Expander Placement Increase Immediate Postoperative Complications in Patients with Breast Cancer?

Abstract

The objectives of this study were to evaluate 1) the rate of immediate breast reconstruction; 2) the frequency of immediate tissue expander placement; and 3) to compare perioperative outcomes in patients who underwent breast reconstruction after mastectomy for breast cancer with immediate tissue expander placement (TE) with those with no reconstruction (NR). Using the Nationwide Inpatient Sample database, we examined the clinical data of patients with breast cancer who underwent mastectomy with or without immediate TE from 2006 to 2010 in the United States. A total of 344,253 patients with breast cancer underwent mastectomy in this period in the United States. Of these patients, 31 per cent had immediate breast reconstruction. We only included patients with mastectomy and no reconstruction (NR: 237,825 patients) and patients who underwent only TE placement with no other reconstruction combination (TE: 61,178 patients) to this study. Patients in the TE group had a lower overall postoperative complication rate (2.6 vs 5.5%; P < 0.01) and lower in-hospital mortality rate (0.01 vs 0.09%; P < 0.01) compared with the NR group. Fifty-three per cent of patients in the NR group were discharged the day of surgery compared with 36 per cent of patients in the TE group. Using multivariate regression analyses and adjusting patient characteristics and comorbidities, patients in the TE group had a significantly lower overall complication rate (adjusted odds ratio [AOR], 0.6) and lower in-hospital mortality (AOR, 0.2) compared with the NR group. The rate of immediate reconstruction is 31 per cent. TE alone is the most common type of immediate reconstruction (57%). There is a lower complication rate for the patients who underwent immediate TE versus the no-reconstruction cohort.
