Comparing outcomes of single-port insufflation endoscopic breast-conserving surgery and conventional open approach for breast cancer.

Background: In the surgical treatment of breast cancer, the goal of surgeons is to continually create and improve minimally invasive surgical techniques to increase patients' quality of life. Currently, routine breast-conserving surgery is often performed using two obvious incisions. Here, we compare the clinical efficacy and aesthetic outcomes of a novel technique using one incision, called 'single-port insufflation endoscopic breast-conserving surgery' (SIE-BCS), vs. conventional breast-conserving surgery (C-BCS) in patients with early-stage breast cancer. Methods: A total of 180 patients with stage I or stage II breast cancer participated in this study, of whom 63 underwent SIE-BCS and 117 underwent C-BCS. Logistic regression analysis was conducted to assess the risk of local recurrence and metastasis. Aesthetic outcomes were evaluated using the BREAST-Q scale. Results: The mean operation time was significantly longer for SIE-BCS (194.9 ± 71.5 min) than for C-BCS (140.3 ± 56.9 min), but the mean incision length was significantly shorter for SIE-BCS than for C-BCS (3.4 ± 1.2 cm vs. 8.6 ± 2.3 cm). While both surgeries yielded similar BREAST-Q ratings for satisfaction with breasts and sexual well-being, SIE-BCS was associated with significantly better ratings for physical well-being (chest area) and psychological well-being. Additionally, SIE-BCS was associated with decreased rates of adverse effects of radiation. The preliminary analysis showed that SIE-BCS did not increase the risk of local recurrence or metastasis. Conclusion: The novel single-port insufflation endoscopic assisted BCS technique is feasible, safe, and improves patients' postoperative comfort and psychological well-being, as compared to the conventional technique.
