Abstract: Objective  Compare the differences between perioperative related indicators of thoracoscopic segmentectomy and wedge resection in the treatment of early stage lung cancer.
Methods  From 2019 to 2020, 65 patients were diagnosed with early stage lung cancer,divided them into two groups,32 cases of thoracoscopic segmentectomy group and  33 cases of thoracoscopic wedge resection group,compare the difference in operation time,blood loss,postoperative drainage volume,postoperative chest tube drainage duration，postoperative hospital stay，pain degree in the 24th and 48th hour after surgery and early postoperative complication rate.
Results  The value of the segmentectomy group  is larger than the wedge resection group in terms of operation time,blood loss,postoperative  drainage volume,postoperative chest tube drainage duration,postoperative hospital stay,and the difference is statistically significant (P<0.05);there was no significant difference between the two groups of patients in the comparison of pain degree at 24 hours and 48 hours after operation and the comparison of the incidence of early postoperative complications(P>0.05).
Conclusion  Both thoracoscopic segmentectomy and thoracoscopic wedge resection are effective and safe in the treatment of early stage lung cancer,and the corresponding surgical method should be selected according to the actual situation.
