Objective  To explore the guiding significance of preoperative 3D reconstruction for pulmonary nodule location and thoracoscopic surgical method selection in lung cancer patients. Methods  The clinical data of the patients with preoperative 3D reconstruction in our China-Japan Friendship Hospital between January and November 2023 were retrospectively analyzed. Preoperative surgical planning was performed using 3D reconstruction. Different surgical procedure, including wedge resection, segmentectomy, lobectomy, or combined surgical procedure were performed based on tumor location, size and distance from the pleura. Results  A total of 115 patients were included with 45 males and 67 females, at an average age of 25-84 (58.29±11.36) years and successfully completed the operation. Fifty-five (47.8%) patients' nodule diameter was tangent cross-section, among whom twenty-five (21.7%) patients of nodules crossed sections. There were 21 patients of wedge resection in the outer 1/3 nodules of CT, which had shorter operation time and less cost (P<0.001) and less intraoperative bleeding (P=0.019). For the crossing sections or edge crossing sections nodules of the middle and inner of CT, 6 patients were of simple pulmonary segmentectomy, 8 patients of combined with sub-segmentectomy, 7 patients of combined segmentectomy, 5 patients of lobectomy, and 3 patients of wedge resection. Conclusion  The proportion of cross-segment pulmonary nodules is relatively high. For the outer 1/3 nodules of CT, compared with pulmonary segmental resection combined with adjacent lung tissue resection, wedge resection can also ensure sufficient surgical margin, and the middle and inner 1/3 nodules of CT need to be combined with adjacent pulmonary tissue resection to ensure the surgical edge.
