A meticulous surgical procedure to prevent local recurrence is required during segmentectomy for clinical stage I non-small-cell primary lung cancer. In this article, we demonstrated the validity of hybrid VATS segmentectomy. Methods: Of these 125 patients, 62 (49.6%) underwent intensively radical segmentectomy (RS). The remaining 63 (50.4%) patients underwent palliative segmentectomy (PS). We used two 2-cm ports and performed a muscle-sparing mini-thoracotomy in which a partially open metal retractor allowed direct, thoracoscopic visualization as hybrid VATS segmentectomy in 63.2% of our cases. Results: The consolidation/tumor ratio obtained with thin-sliced computed tomography was significantly lower in RS cases than in PS cases (P=0.001). The proportion of pathological stage IA cases was significantly higher in RS cases (95.2%) than in PS cases (66.7%; P Conclusions: During segmentectomy, the most critical consideration is establishment of sufficient surgical margins around the cancer. Our hybrid approach that includes meticulous surgical manipulations may produce sufficient surgical margins. UR - https://jtd.amegroups.org/article/view/20373
