Treatment of thoracoscopic subsegmental resection under the guidance of 3D reconstruction of bronchial blood vessels of pulmonary for pulmonary nodule / 中国医学装备

ABSTRACT

Objective:To analyze the effect of thoracoscopic subsegmental resection under the guidance of three dimensional(3D)computed tomography bronchography and angiography(3D-CTBA)for resection of pulmonary nodules.Methods:A total of 40 patients who underwent 3D-CTBA-guided thoracoscopic subsegmental resection in Nanjing Jiangbei Hospital of Nantong University from January 2020 to October 2021 were selected as the observation group,and other 35 patients who underwent 3D-CTBA-guided thoracoscopic pulmonary segmentectomy were selected as the control group.The intraoperative and postoperative conditions,and the incidence of postoperative complications of the two groups were observed.Results:The differences of amount of intraoperative blood loss,average margin width,postoperative drainage,retention time of drainage tube between observation group and control group were significant(t=8.644,2.862,10.03,3.277,P<0.05),respectively.The numbers of occurring postoperative chest leakage,pulmonary infection and hemoptysis in observation group and control group were respectively"3,1,1"and"2,1,2".The incidences of complications of two groups were respectively 12.5%and 14.29%,without statistical significance between the two groups(P>0.05).Conclusion:3D-CTBA-guided thoracoscopic subsegmental resection can shorten the operation time,and reduce intraoperative blood loss and the injury of tracheas and blood vessels,and improve the postoperative recovery of patients.
