Clinical Study Of Preoperative CT-guided Hook-wire Localization For Pulmonary Ground-glass Nodule In Video-assisted Thoracoscopic Surgery

Objective:Through a comparative study with the relevant indexes of traditional intraoperative experiential localization,the safety and clinical application value of CT-guided hook wire localization in the thoracoscopic resection of solitary pulmonary ground-glass nodule were discussed,and the practical experience was analyzed and summarized,so as to provide a reference for the thoracoscopic surgical treatment of pulmonary ground-glass noduleMethod:According to the inclusion criteria and exclusion criteria,60 patients who underwent surgical treatment in the Department of Thoracic Surgery of the Third Affiliated Hospital of Kunming Medical University from December 2017 to February 2019,were randomly divided into two groups according to the order of admission:patients underwent CT-guided positioning with hook wire before thoracoscopic surgery were the experimental group,and patients without hook-wired wire guided by CT were used as the control group.The location time,success rate,and location-related complications of the two groups were statistically analyzed.The general clinical data,lung wedge resection time,transthoracic chest opening rate,postoperative hospital stay and pathological results were compared.The data were analyzed using SPSS22.0 software,P<0.05 was statistically significant.Results:All 60 patients underwent successful operation without perioperative death.There were no serious complications in the experimental group before operation.The preoperative localization time(12.0±2.0)min in the experimental group and the intraoperative localization time(16.6±2.5)min in the control group were statistically significant.In the experimental group,30 lesions were successfully located before operation,and the success rate was 100.0%.In the control group,30 cases were successfully located in 26 cases,and the success rate was 86.7%.The difference was statistically significant.The wedge resection time of the experimental group was(13.6±2.2)min,and the wedge resection time of the control group was(22.2±3.5)min.The difference was statistically significant.The postoperative hospital stay was(6.4±0.8)d in the experimental group and(6.9±0.6)d in the control group.The difference was statistically significant.In the experimental group,the transthoracic opening rate was 0.0%,and the conversion rate in the control group was 13.3%.The difference was statistically significant.There were no significant differences in the general clinical data and postoperative pathological findings between the two groups.Conclusion:Through comparative analysis in this study,it can be seen that the positioning with hook wire under CT guidance before the thoracoscopic resection of solitary pulmonary ground-glass nodule has high feasibility and safety,can accurately locate the position of pulmonary ground-glass nodule,and can effectively shorten the time of pulmonary wedge resection and postoperative hospitalization,and significantly decrease the rate of transferring thoracotomy,which is worthy of clinical application.
