Comparative analysis of the clinical effects of different thoracoscopic resection in the treatment of Stage I Non-Small Cell Lung Cancer

To compare and analyze the clinical effects of thoracoscopic lobectomy and segmentectomy in stage I non-small cell lung cancer (NSCLC). This was a retrospective study. Eighty patients with stage I NSCLC treated in Cangzhou People's Hospital from December 2019 to January 2022 were randomly divided into the segmentectomy group and lobectomy group, with 40 cases in each group. Further comparative analysis was carried out focusing on perioperative indexes, maximum ventilation volume (MVV), forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), VAS score of postoperative pain and complications. There was no significant difference in the number of dissected lymph nodes and extubation time between the two groups (p>0.05). The operation time was longer, while intraoperative blood loss was less and the stay of stay in hospital was shorter in the segmentectomy group significantly than those in the lobectomy group (p0.05). Meanwhile, the segmentectomy group had evidently lower VAS scores at 1 d, 3 d and 5 d postoperatively than those in the lobectomy group (p
