It has the highest morbidity and mortality worldwide among all the malignant tumors. Due to the popularization of low-dose CT and other means of examination, more and more patients with lung cancer are detected in the early phase of disease. Anatomical segmentectomy is one of the standard surgical procedures for these small pulmonary nodules or ground glass opacity (GGO), which are clinically highly suspected or puncture confirmed early lung cancer lesions. Dissection of the intersegmental plane in segmentectomy is a difficulty that have puzzled thoracic surgeons for decades because of the complicated anatomic relationship and variations, along with lack of boundary between pulmonary segments. There are two main approaches in the dissection of intersegmental plane: stapling devices and energy instrument separation. However, only a few retrospective studies focused on the perioperative outcomes of these two approaches in segmentectomy, not to mention in robot assisted segmentectomy, and there has been no definitive conclusion about which method is better. So the investigators want to conduct a prospective study, trying to figure out this problem.\n\nThe investigators set incidence rate of postoperative complications as their primary endpoint.
