Objective:We aim to explore the feasibility and safety of the S2b+S3a combined subsegmentectomy for pulmonary nodules between S2 and S3 in the right upper lung. Methods:The clinical data of segmentectomy from 2015 to 2020 in our center was cdlected,the nodule characteristics and perioperative data of the patients received S2b+S3a combined resection was analyzed. Propensity score matching was used to select the right upper lobe(RUL)resection cases with comparable age,gender,and pathological nodule diameter. Results:A total of 46 cases of S2b+S3a resection and 46 matched cases of RUL resection were included. The pathologic malignancy of nodules in the RUL group was higher than that in the S2b+S3a group(P=0.037) and the TNM stage was more advanced(P=0.026). The nodules of the RUL group were deeper than that in the S2b+S3a group(P=0.005). The number of lymph node sampled stations and the total number of sampled lymph nodes in the RUL group were larger than those in the S2b+S3a group(P<0.001). In terms of postoperative data,the drainage volume on the first postoperative day,the total drainage volume,and the duration of chest tube drainage of the S2b+S3a group were all smaller than those in the RUL group. There was no perioperative death in both groups and no postoperative recurrence or death at the follow-up endpoint. Conclusion:S2b+S3a combined subsegmentectomy is a safe and feasible method to manage pulmonary nodules such as early non-small cell lung cancer between S2 and S3 under rational planning.
