超声内镜引导下的经支气管针吸活检术在肺癌分期及分型中的应用

The Application Value of Endobronchial Ultrasound-guided Transbronchial Needle Aspiration in the Staging and Typing of Lung Cancer

目的：探讨超声内镜引导下的经支气管针吸术（EBUS-TBNA）在肺癌淋巴结分期和病理分型中的临床应用价值。方法对术前CT检查拟诊伴有纵隔淋巴结转移的59例肺癌患者行超声内镜引导下的EBUS-TBNA检查，并与其术后病理检查结果进行对比。结果59例患者术前EBUS-TBNA检查诊断淋巴结阳性55例，术后病理检查证实淋巴结转移57例，诊断敏感性为96.5%；病理分型符合率为91.2%；术前EBUS-TBNA检查N分期与术后病理检查N分期对比准确性为93.2%。59例患者接受EBUS-TBNA检查后均未发生并发症。结论经EBUS-TBNA检查对肺癌淋巴结分期及病理分型具有高度敏感性和准确性，并且创伤小、安全性高，有较高临床应用价值。

Objective To explore the application value of endobronchial ultrasound-guided transbronchial needle aspiration （EBUS-TBNA） in the staging and typing of lung cancer. Methods To 59 patients of primary bronchogenic carcinoma with suspected lymph node metastasis by chest CT scan, EBUS-TBNA were performed before operation. The cytological results were compared with the pathological ones after operation. Results In 59 patiens, the diagnosis of EBUS-TBNA examination before operation with 55 cases were positive. 57 cases were diagnosed lymph node metastasis by pathology after operation, the sensitivity diagnostic rate were 96.5%. The coincidence rate of pathology typing were 91.2%. The overall accuracy of c-N by EBUS-TBNA before opera-tion was 93.2%compared with p-N by pathological examination after operation. 59 patients had no other serious complications by EBUS-TBNA examination. Conclusion The EBUS-TBNA is small hurt and safe, and it has high sensitivigy and accuracy for lymph node staging and pathology typing of lung cancer.
