肺小结节胸腔镜术前定位中CT三维重建联合CT引导下医用胶定位的价值

Value of CT Three-dimensional Reconstruction Combined with CT Guided Medical Adhesive Localization in Preoperative Thoracoscopic Localization of Pulmonary Nodules

目的 分析肺小结节胸腔镜术前定位中CT三维重建联合CT引导下医用胶定位的价值。方法 选取2019年11月—2022年10月铜陵市人民医院心胸外科行胸腔镜手术治疗的77例肺小结节患者为研究对象,全部为单一结节患者。根据不同定位方法分为两组,对照组(38例)仅接受胸部CT扫描定位,观察组(39例)在CT三维重建图像基础上联合CT引导医用胶定位。比较两组结节定位的成功率、术前定位时间。结果 观察组结节定位的成功率为100.00%(39/39),高于对照组的89.47%(34/38),差异有统计学意义(χ^(2)=4.330,P=0.037)。观察组术前定位时间短于对照组,差异无统计学意义(P>0.05)。结论 术前CT三维重建联合CT引导下医用胶定位能有效提升肺小结节定位的成功率。

Objective To analyze the value of 3D CT reconstruction combined with CT-guided medical glue localization in thoracoscopic preoperative location of pulmonary nodules.Methods Seventy-seven patients with small pulmonary nodules who underwent thoracoscopic surgery in the Department of cardiothoracic Surgery of Tongling People's Hospital from November 2019 to October 2022 were selected as the study objects,all of whom were single nodules.They were divided into two groups according to the different positioning methods.The control group(38 cases) only received chest CT scan for localization.Observation group(39 cases) combined with CT-guided medical glue localization on the basis of CT 3D reconstruction images.The success rate and preoperative localization time of nodules were compared between the two groups.Results The success rate of nodule localization in observation group was 100.00%(39/39),which was higher than that in control group 89.47%(34/38),and the difference was statistically significant(χ^(2)=4.330,P=0.037).The preoperative positioning time of the observation group was shorter than that of the control group,the difference was not statistically significant(P>0.05).Conclusion The combination of preoperative CT three-dimensional reconstruction and CT guided medical adhesive localization can effectively improve the success rate of locating pulmonary nodules.
