摘要:

目的 比较分析超声引导下胸膜穿刺获取的病理组织及胸腔积液标本在疑似结核性胸膜炎中的诊断价值。方法 搜集2016年1月至2018年5月在西安市胸科医院初次就诊的298例疑似结核性胸膜炎患者,其中临床确诊结核性胸膜炎患者112例,非结核性胸膜炎患者186例。所有患者均通过超声引导下胸膜穿刺获取病理组织和胸腔积液标本,对活检组织进行病理学切片检查(简称“病理检查”),胸腔积液分别进行结核分枝杆菌培养(浓缩集菌法,采用液体培养BACTEC MGIT 960操作系统,简称“MGIT 960培养”)、全自动医用PCR分析系统(GeneXpert MTB/RIF,简称“GeneXpert检测”)和抗酸杆菌染色涂片检查(简称“涂片检查”)。上述各种方法以临床确诊患者为参考标准,得出各自的诊断敏感度、特异度、阳性预测值、阴性预测值、约登指数,以评价各种检测方法诊断结核性胸膜炎的效能。结果 病理检查、MGIT 960培养、GeneXpert检测、涂片检查以临床确诊结果为参考标准的诊断敏感度分别为41.96%(47/112)、73.21%(82/112)、58.93%(66/112)和2.68%(3/112);特异度分别为99.46%(185/186)、100.00%(186/186)、100.00%(186/186)、100.00%(186/186);约登指数分别为0.41、0.73、0.59、0.02。结论 超声引导下胸膜穿刺获取标本采用各种技术与方法进行检测,结果证明胸腔积液标本采用浓缩集菌法进行MGIT 960培养相对其他检测技术与方法具有较好的敏感度、特异度,约登指数最高,具有良好的临床诊断结核性胸膜炎的价值。

Abstract:

Objective To compare and analyze the diagnostic value of pathological tissue and pleural effusion samples obtained by ultrasound-guided pleural puncture in suspected tuberculous pleurisy.Methods Two hundred and ninety-eight patients with suspected tuberculous pleurisy who were admitted to Xi’an Chest Hospital from January 2016 to May 2018 were retrospectively analyzed. Among them, 112 cases were clinically diagnosed as tuberculous pleurisy and 186 cases as non-tuberculous pleurisy. The specimens of pathological tissue and pleural effusions were obtained under the guidance of ultrasound, and the pathological sections of the biopsies were examined (“pathological examination”). The pleural effusions were cultured with Mycobacteria tuberculosis (concentrated collection method, liquid culture BACTEC MGIT 960 operating system, “MGIT 960 culture”). GeneXpert MTB/RIF detection (“GeneXpert detection”) and acid-fast bacillus staining smear examination (“smear examination”). The above-mentioned methods took clinically confirmed patients as reference criteria, and obtained their diagnostic sensitivity, specificity, positive predictive value, negative predictive value and Yoden index, in order to evaluate the effectiveness of various detection methods in the diagnosis of tuberculous pleurisy.Results The sensitivity of pathological examination, MGIT 960 culture, GeneXpert detection and smear examination were 41.96% (47/112), 73.21% (82/112), 58.93% (66/112) and 2.68% (3/112).The specificity was 99.46% (185/186), 100.00% (186/186), 100.00% (186/186) and 100.00% (186/186). The Yoden index was 0.41, 0.73, 0.59, 0.02.Conclusion The results showed that MGIT 960 culture with concentrated bacteria collection method had better sensitivity and specificity than other detection techniques and methods. The Yoden index was the highest, and had good clinical diagnostic value for tuberculous pleurisy.
