Abstract	Objective To determine the learning curve for double-port video-assisted thoracoscopic (VATS) lung segmentectomy performed by the same surgical team in our center. Methods We retrospectively collected clinical data from 193 patients who underwent double-port video-assisted thoracoscopic lung segmentectomy from March 2017 to March 2023. The operative time (OT) was analyzed using the cumulative sum (CUSUM) method, and two stages of the learning curve were obtained. Propensity score matching (PSM) was performed for age, sex, underlying disease, and single-segment resection via radius matching. The OT, estimated amount of intraoperative blood loss, and other complications were analyzed. Results We generated a graph of the CUSUM of the OT and found that the learning curve could be differentiated into two stages: the learning stage (1st to 95th surgery) and the proficiency stage (96th to 193rd surgery). Before PSM, there were significant differences in the OT, extent of lymph node station dissection, amount of drainage on the day of surgery, amount of drainage on the first postoperative day, estimated amount of intraoperative blood loss, and length of hospital stay after surgery. There were no significant differences in the average amount of drainage 3 days after surgery, postoperative tube time, or number of intraoperative revolutions. However, after PSM, there were significant differences in the OT, number of lymph node stations removed, amount of drainage on the day of surgery, and amount of drainage on the first postoperative day. There were no significant differences in the estimated amount of intraoperative blood loss, length of hospital stay after surgery, average amount of drainage for 3 days after surgery, postoperative tube time, or number of intraoperative revolutions. Conclusion In our center, the learning curve for double-port video-assisted thoracoscopic lung segmentectomy transitions from the learning stage to the proficiency stage when the number of surgical cases reaches 95. There were significant differences in the OT, number of lymph node stations removed, amount of drainage on the day of surgery, and amount of drainage on the first postoperative day.
