| Objective: The ground glass opacity(GGO)lesion location is a technical difficulty in minimally invasive surgical resection.Various kinds of localization methods have been reported,but each method has its own shortcomings.In this study,through clinical case analysis,the operability and safety of preoperative Hook-wire positioning in video-assisted thoracoscopic surgery(VATS)were thoroughly investigated in order to provide a basis for finding a better positioning method for preoperative lung ground glass opacity.Methods: In this study,a total of 60 GGO patients were collected and the clinical data of 53 GGO patients included in the study were compared according to the inclusion exclusion criteria.The study collected the patient's age,gender,the ratio of smokers and non-smokers,GGO diameter,the distance from the GGO to the chest wall,the GGO CT value,the time required for thoracoscopic surgical resection of the lesion,the distance between the resection margin,the number of intraoperative nails,number of intraoperative repairs,rapid pathological examinations,finding the number of focal incisions,blood loss during surgery,postoperative removal of chest drainage tube,postoperative hospital stay,total hospital cost,and Hook-wire positioning need time,positioning CT scan times,complications caused by positioning operations and other indicators.Patients with preoperative Hook-wire positioning were used as the experimental group,and patients without preoperative positioning were used as the control group.The significance of Hook-wire positioning before surgery was clarified by comparing the differences between the two groups of data.At the same time,we analyzed the various problems encountered during the Hook-wire positioning and surgical procedure and the treatment methods to clarify the operability of its clinical application.Results: A total of 53 patients were included in the study,including 26 in the untargeted group and 27 in the positioning group.Through statistical analysis,the age,gender,ratio of smokers to non-smokers,distance between GGO nodules and the chest wall,distance between the experimental and control groups,the distance from the margin to the lesion,the number of nails used during the operation,the number of rapid pathological examinations,and There was no significant difference in the amount of blood loss,postoperative drainage time,postoperative hospital stay,and total hospital expenses.The GGO nodule diameter(non-positioned group 10.90±3.48 mm,positioning group 9.07±2.71,P=0.037);CT values of GGO nodules(unpositioned group-459.35±181.61 HU,positioning group-570.81±127.71 HU,P=0.012);time required for minimally invasive resection(33.00±8.94 min in unpositioned group,22.67±7.66 min in positioning group,P=0.001);number of intraoperative supplementary cuts(0.15±0.37 in untargeted group,0 in localized group P=0.034);Finding the number of focal incisions(non-localized group 1.69±1.01 times,positioning group 1.15±0.36 times,P=0.011)and other observational indicators have significant differences.The GGO nodule diameter and the CT value of GGO nodules were not correlated with the time required for minimally invasive resection of the lesion,the number of intraoperative repairs,and the number of times the lesion was cut.Conclusion: Preoperative Hook-wire positioning of GGO nodules is safe,effective and feasible.Although there will be a small number of complications,they can be effectively controlled and no serious complications occur after positioning.The preoperative Hook-wire positioning of GGO nodules can facilitate the search for lesions during surgery,significantly shorten the time for resection of the lesions,and accelerate the surgical process. |
