Abstract:
35 Background: Bilateral mastectomies (BM) are generally performed by a single surgeon (SS). A two-attending ‘co-surgeon’ (CS) technique, in which each surgeon concurrently performs a unilateral mastectomy, offers an alternative operative approach. We sought to examine differences in general surgery time (GST), overall surgery time (OST), and patient outcomes for BM performed by CS and SS at our institution. Methods: Patients undergoing BM with tissue expander reconstruction (BMTR) between January 2010 and May 2014 at our institution were identified and divided into SS and CS cases. Operative records were used to calculate GST (incision to end of BM procedure), reconstruction time (plastic surgery start time to end of reconstruction) and OST (OST = GST + reconstructive time). Patient age, presence and stage of cancer, breast weight, axillary procedure [sentinel node biopsy (SNB) or axillary dissection (ALND)], and 30-day postoperative complications were extracted from medical charts. Differences in GST and OST between CS and SS performed cases were assessed using a t-test. A linear regression was performed to identify factors contributing to GST. Results: We identified 116 BMTR cases performed by 8 breast surgeons, [CS, n = 67 (57.8%); SS, n = 49 (42.2%)] . Demographic characteristics did not significantly differ between groups. In the bivariate analyses, GST and OST for CS cases were significantly shorter than for SS, 75.8 vs 116.8 minutes, p 〈 0.0001, and 255.2 vs 278.3 minutes, p = 0.005, respectively. The linear regression demonstrated a significant decrease in GST when BMTR was performed by CS (β = -38.82, p 〈 0.0001); total breast weight (β = 0.0093, p = 0.03) and axillary dissection (β = 28.69, p = 0.0003) were found to significantly impact GST. Conclusions: The GST of BMTR is significantly decreased using a CS-approach without impacting complication rates. However, the degree of GST and OST-reduction suggests the addition of a CS does not proportionally impact surgical time as would be expected. A CS-approach may be more beneficial for patients with large total breast weight or those requiring ALND. A larger study is warranted to better characterize time, cost, and outcomes of the CS-approach for BM.
