Endoscopic Bilateral Nipple-sparing Mastectomy via a Single Axillary Incision with Immediate Pre-pectoral Implant-based Breast Reconstruction.

Oncoplastic breast surgery, with its focus on improving cosmetic outcomes while maintaining oncological safety, has fundamentally transformed the landscape of breast cancer surgical treatment, giving rise to an array of techniques for breast reconstruction. Nipple-sparing mastectomy (NSM) with immediate implant-based breast reconstruction (IBBR) has emerged as a cornerstone in managing early breast cancer. Aligned with the principles of minimally invasive surgery, recent years have witnessed the widespread integration of endoscopic approaches in breast surgery, encompassing procedures like endoscopic breast-conserving surgery (E-BCS) and endoscopic nipple-sparing mastectomy (E-NSM), among others. Capitalizing on the advantages of inconspicuous and shorter incisions, improved visibility, and the avoidance of radiation therapy, the popularity of E-NSM with IBBR is on the rise. However, conventional E-NSM with IBBR often requires two or more incisions, which can result in suboptimal cosmetic outcomes and even prosthesis loss.This paper presents a comprehensive account of the intricate surgical procedures involved in endoscopic bilateral nipple-sparing mastectomy with immediate pre-pectoral implant-based breast reconstruction. The insights shared are drawn from the collective experience of our institution. Notable benefits associated with the described surgical approach encompass enhanced cosmetic outcomes, improved postoperative quality of life, and enhanced physiological functions attributable to the application of pre-pectoral implant-based breast reconstruction through a single incision.
