Background
Bilateral mastectomies (BM) are traditionally performed by single surgeons (SS); a co-surgeon (CS) technique, where each surgeon concurrently performs a unilateral mastectomy, offers an alternative approach. We examined differences in general surgery time (GST), overall surgery time (OST), and patient complications for BM performed by CS and SS.
Methods
Patients undergoing BM with tissue expander reconstruction (BMTR) between January 2010 and May 2014 at our center were identified through operative case logs. GST (incision to end of BM procedure), reconstruction duration (RST) (plastic surgery start to end of reconstruction) and OST (OST= GST + RST) was calculated. Patient age, presence/stage of cancer, breast weight, axillary-procedure performed, and 30-day postoperative complications were extracted from medical records. Differences in GST and OST between CS- and SS-cases were assessed with a t-test. A multivariate linear regression was fit to identify factors associated with GST.
Results
116 BMTR cases were performed [CS, n=67 (57.8%); SS, n=49 (42.2%)]. Demographic characteristics did not differ between groups. GST and OST were significantly shorter for CS-cases, 75.8 vs. 116.8 minutes, p<0.0001, and 255.2 vs. 278.3 minutes, p=0.005, respectively. Presence of a CS significantly reduces BMTR time (β=−38.82, p<0.0001). Breast weight (β=0.0093, p=0.03) and axillary dissection (β=28.69, p=0.0003) also impacted GST.
Conclusions
The co-surgeon approach to BMTR reduced both GST and OST, however the degree of time-savings (35.1% and 8.3% respectively) was less than hypothesized. A larger study is warranted to better characterize time, cost, and outcomes of the CS-approach for BM.
