Abstract: Objective To compare the therapeutic effects of segmentectomy and lung wedge resection for lung cancer with a diameter ≤ 2cm and CT shows that ground glass nodules ≥ 50%.
Methods From January 2020 to July 2021,38 patients with lung adenocarcinoma who underwent segmental resection or pulmonary wedge resection at Zhongnan Hospital of Wuhan University were enrolled.Among them:16 cases in the segmental resection group(segmental resection group);22 cases in the wedge resection group(wedge resection group),compared the clinical data of the two groups of patients.
Results There was no perioperative death in both groups.Operation time [(131.6±40.2)min vs.(20.3±10.2) min],intraoperative blood loss [(67.2±49.1) ml vs.(9.9±5.1) ml],drainage tube extubation time[(3.5±1.5)d vs.(1.5±0.5)d] and hospitalization time [(4.5±3.5)d vs.(2.5±1.5)d] in the segmental resection group and the wedge resection group were statistically significant(P＜0.05).All these aspects,resection the wedge resection group was significantly better than the segment resection group.
Conclusion Pulmonary wedge resection is beneficial to the rapid recovery of patients with peripheral(1/3 of outside the lung parenchyma) and pulmonary adenocarcinoma with diameter ≤2cm.
