<p>Background: Breast-conserving surgery (BCS) has evolved substantially with the introduction of minimally invasive techniques.

The mean age was 53.9 years in the R-BCS group and 54.4 years in the E-BCS group.

摘要

Background: Breast-conserving surgery (BCS) has evolved substantially with the introduction of minimally invasive techniques. Endoscopic BCS (E-BCS) has been applied for more than two decades, whereas robotic breast surgery, particularly robotic BCS (R-BCS), remains in an early developmental stage. This study compared the clinical outcomes of R-BCS and E-BCS in patients with breast cancer. Methods: We performed a single-center retrospective analysis of consecutive breast cancer patients who underwent either R-BCS or E-BCS between April 2021 and August 2025. The results of this cohort were reported in the present study. Results: The study enrolled 132 patients, of whom 72 underwent R-BCS and 60 underwent E-BCS. All patients had unilateral disease. The mean age was 53.9 years in the R-BCS group and 54.4 years in the E-BCS group. After excluding cases with axillary lymph node dissection, the mean operative time was significantly shorter for R-BCS than for E-BCS (148.4 ± 36.9 vs. 167.5 ± 35.7 min, p = 0.034), and intraoperative blood loss was significantly lower in the R-BCS group (13.0 ± 7.0 vs. 19.8 ± 9.4 ml, p = 0.001). One patient in each group had a positive surgical margin, which was converted to negative after re-excision. No conversions to alternative surgical procedures occurred. Perioperative complication rates were comparable between groups, and both achieved favorable aesthetic outcomes. R-BCS demonstrated higher mean scores for scar appearance and length than E-BCS. Conclusions: R-BCS was associated with shorter operative time and reduced blood loss compared with E-BCS, which represents a promising surgical technique.
