Abstract：Objective:To investigate the value of preoperative CT-guided novel pulmonary nodule localization needles and Hook-wire localization needles in thoracoscopic resection of small pulmonary nodules,and to provide more evidence-based evi-dence for the choice of preoperative localization methods.Methods:Clinical data of 80 patients who underwent thoracoscopic sur-gery for pulmonary nodules and underwent preoperative localization of pulmonary nodules at the hospital from January 2022 to Oc-tober 2022 were retrospectively analyzed.They were divided into the Hook-wire group and the new lung nodule localization needle group according to the type of localization needles.Patients in the Hook-wire localization needle group received preoperative CT-guided Hook-wire localization of lung nodules,and patients in the new lung nodule localization needle group received preopera-tive CT-guided localization of lung nodules.The localization effect and patient prognosis were compared between the two groups.Results:There was no statistically significant difference in the comparison of nodule diameter,distance of the nodule from the wall pleura,localization time,incidence of pneumothorax,and incidence of hemorrhage between the two groups of patients(t/χ2= 0.050,-0.782,0.065,1.967,-0.298,1.458,0.871,P＞0.05).The post-positioning pain scores and the incidence of displacement or decoupling were significantly lower in the new pulmonary nodule localization needle group than in the Hook-wire group,and the difference was statistically significant(t/χ2=-6.671,3.914,P＜0.05).Conclusion:The use of CT-guided positioning of a new type of pulmonary nodule localization needle before thoracoscopic resection of small pulmonary nodules can effectively reduce the risk of hook wire displacement or dislocation and alleviate the post-positioning pain.
