Abstract: 【Abstract】〓Objective〓To summarize the diagnostic and therapic experence of video-assisted thoracoscopic surgery for subcentimeter pulmonary nodules. Methods〓Thirty-eight patients with subcent-imeter pulmonary nodules highly suggested of a malignancy by CT scan were retrospectively analyzed. Perioperative period data about hookwire location and video-assisted thoracoscopic surgery was summarized..Pathological results of the subcentimeter pulmonary nodules was analyzed. Results〓All lesions were successfully identified by the hookwire approach..All the operations were completed with no serious complication,.including wedge resection in 24 cases, segmentectomy in 4 and lobectomy with lymph node dissection in 10..Pathological diagnosis identified 15 invasive carcinomas,.5 pre-invasive carcinomas, 2 metastatic tumors and 16 benign lesions..The pathological coincidence rate between frozen section and paraffin section was 92.1%..Conclusion〓Subcentimeter pulmonary nodules are difficultly diagnosed in preoperative and intranperative period..Video-assisted thoracoscopic surgery is one of the effective and safe techniques for the diagnosis and therapy of subcentimeter pulmonary nodules.
