ABSTRACT
Objective To research high efficiency ,safety and complications of transbronchial needle aspiration biopsy under the guidance of ultrasound bronchoscope (EBUS‐TBNA ) in the early stage diagnosis of pulmonary disease .Methods Totally 28 patients showed intrathoracic mass or mediastinal lymph nodes by chest CT treated from May 2013 to May 2014 underwent EBUS‐TBNA ,and conducted biopsy for pathological examination .Results Among all the 28 patients ,23 patients underwent EBUS‐ TB‐NA ,10 patients were diagnosed as lung cancer ,4 patients had metastatic tumors ,3 patients were diagnosed lymphoma ,3 people were tuberculosis ,2 people were sarcoidosis ,1 patients with inflammatory .The EBUS‐TBNA diagnosis rate of malignant tumor was 74 .0% ,and the diagnosis rate was significantly higher than expectation (53 .2% ,P<0 .01) .The accuracy of EBUS‐TBNA diagno‐sis was as follow :91 .0% for lung cancer ,100 .0% for lymphoma ,75 .0% for metastatic tumor;75 .0% for tuberculosis ,50 .0% for sarcoidosis ,and 100 .0% for inflammatory lesions .Among all EBUS‐TBNA patients ,only two patients had mild hypoxia and one patient had bleeding .Conclusion EBUS‐TBNA was an effective ,minimally invasive ,safe means of inspection for the early diagnosis of respiratory diseases ,especially of mediastinal mass .
