【摘要】 目的探讨经超声支气管镜引导针吸活检术(EBUS-TBNA)在纵膈及肺门淋巴结以及肺内病变诊断中的价值及应用。方法回顾性总结2014年6月至2015年10月在我科收治的32例接受EBUS-TBNA患者的临床资料。其中纵膈淋巴结肿大患者13例,单纯肺部病变患者4例,肺部病变合并纵膈淋巴结肿大患者15例。结果通过对32例患者检查结果分析,22例患者明确诊断。其中,恶性病变12例,良性病变10例;12例未能确诊。未能确诊者采用经皮肺穿刺活检或全身PET-CT扫描明确诊断。EBUS-TBNA敏感性、特异性、分别为76%和100%,阳性预测值以及阴性预测值分别为100%和30%。所有患者均未出现严重并发症。结论 EBUS-TBNA是近年逐渐开始推广应用的支气管镜下有创诊疗技术,是安全、高效的微创诊疗方法,在诊断纵膈及肺部疾病中具有重要意义。更多还原

【Abstract】 Objective To determine the efficacy and safety of endobronchial ultrasound-guided transbronchial needle aspiration( EBUS-TBNA) for dagnosis of the mediastinum and hilar lesions. Methods A retrospective study about EBUS-TBNA from 32 patients with mediastinum and hilar lesions was carried out.The sensitivity,specificity,positive predictive value,negative predictive value and diagnostic accuracy of EBUS-TBNA were evaluated. Results Among all the 32 patients,specimens were of histological quality showed malignant invasion in 12 cases and benign granuloma disease in 10 cases. The overall sensitivity,specificity,positive predictive value and negative predictive value of EBUS-TBNA for all the patients were76%,100%,100%,30%,respectively. There was no severe complication happened. Conclusions EBUSTBNA is a valueable and safe transbronchial needle aspiration biopsy of mediastinum and hilar lesions.更多还原
