However, surgical variability and patient discomfort under regional anesthesia present challenges for training programs and consistent clinical outcomes. To address this, we implemented a breast modular resection (BMR) surgical teaching course designed to deconstruct BCS\u2009+\u2009SLNB into standardized modules and evaluated its impact on training effectiveness and patient outcomes in the day surgery setting under regional anesthesia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A total of 273 patients underwent BCS with SLNB between 2019 and 2022, performed by six attending breast surgeons.

All surgeries were performed under regional anesthesia. Clinical and subjective outcome indicators, such as re\u2010excision rate, pain scores, cosmetic satisfaction, and hospital stay, were analyzed.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The BMR group showed significantly more favorable perioperative outcomes, including lower re\u2010excision rates (3.85% vs. 11.88%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.038), reduced intraoperative pain (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05), decreased seroma incidence (9.62% vs. 20.79%,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.032), and enhanced breast symmetry satisfaction (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.008).
