目的:探讨超声支气管镜引导下经支气管针吸活检(EBUS-TBNA)在肺癌诊断中的初步应用价值。方法:对2011年5月至2012年1月住院的肺部占位病变患者18例行EBUS-TBNA穿刺,标本行病理学检查。结果:18例患者均顺利完成,无1例发生并发症。18例患者中经病理学检查确诊为肺癌的有12例,共穿刺淋巴结31组,每组淋巴结平均操作时间为10.7 min。EBUS-TBNA的灵敏度、特异度、准确率分别为100%、83.3%、94.4%。结论:EBUS-TBNA检查安全性好,准确率高,是诊断肺癌较好的方法。
Objective: To investigate the preliminary value of transbronchial needle aspiration biopsy (EBUS-TBNA) guided by ultrasound bronchoscopy in the diagnosis of lung cancer. Methods: EBUS-TBNA puncture was performed on 18 patients with lung-occupying lesions in hospital from May 2011 to January 2012. The specimens were examined by pathology. Results: All 18 patients were successfully completed without complications. Of the 18 patients diagnosed with lung cancer by pathology, 12 had a total of 31 punctured lymph nodes, with an average operation time of 10.7 minutes per lymph node. The sensitivity, specificity and accuracy of EBUS-TBNA were 100%, 83.3% and 94.4% respectively. Conclusion: EBUS-TBNA has good safety and high accuracy, which is a good method to diagnose lung cancer.
