薄层CT画图导航联合快速现场评价在肺外周型病变中的诊断价值

The diagnostic value of thin slice CT map navigation combined with rapid field assessment in peripheral pulmonary diseases

目的:分析薄层CT画图导航联合快速现场评价(ROSE)技术在肺外周型病变(PPLs)中的诊断价值。方法:选择2022年2月—2024年2月收治的80例拟诊为PPLs患者作为研究对象,随机分为对照组和观察组,每组40例。对照组使用薄层CT画图导航行常规气管镜下活组织检查,观察组使用薄层CT画图导航联合ROSE技术进行活组织检查。以术后常规细胞以及组织学活组织检查结果为金标准,比较两组并发症、诊断阳性率、穿刺次数以及穿刺时间。根据受试者特征曲线(ROC)计算薄层CT+ROSE在肺外周病灶的诊断效能。结果:观察组并发症发生率高于对照组,但差异无统计学意义(P>0.05)。观察组穿刺次数低于对照组(P<0.05),穿刺时间长于对照组(P>0.05)。观察组总阳性率高于对照组,但差异无统计学意义(P>0.05)。ROC曲线结果分析,薄层CT画图导航行常规气管镜下活组织检查、薄层CT画图导航联合ROSE技术活组织检查早期预测PPLs的ROC曲线下面积(AUC)分别为0.793和0.872。结论:薄层CT导航联合ROSE技术活组织检查诊断PPLs具有良好的诊断阳性率,能够提高标本质量,缩短检测时间,安全性较好。

Objective:To analyze the diagnostic value of thin slice CT mapping navigation combined with rapid field assessment(ROSE)in pulmonary peripheral lesions(PPLs).Methods:A total of 80 patients with suspected PPLs admitted to hospital from February 2022 to February 2024 were randomly divided into control group and observation group,with 40 cases in each group.The control group was treated with thin-layer CT navigation for routine bronchoscopy biopsy,and the observation group was treated with thin-layer CT navigation combined with ROSE technique for biopsy.According to the results of routine cell and histological examination after operation as the gold standard,the complications,diagnostic positive rate,puncture times and puncture time were compared between the two groups.The diagnostic efficacy of thin-slice CT+ROSE in peripheral pulmonary lesions was calculated according to the ROC curve.Results:The incidence of complications in the observation group was higher than that in the control group,but there was no significant difference between the two groups(P>0.05).The number of punctures in the observation group was lower than that in the control group(P<0.05),the puncture time was higher than that of the control group(P>0.05).The total positive rate of the observation group was higher than that of the control group,but there was no significant difference between the two groups(P>0.05).According to the results of ROC curve analysis,the AUC of conventional bronchoscopy biopsy and thin-layer CT navigation combined with ROSE biopsy for early prediction of PPLs were 0.793 and 0.872,respectively.Conclusion:Thin-slice CT navigation combined with ROSE biopsy has a good diagnostic positive rate for PPLs,which can improve specimen quality,shorten detection time and has good safety.
