Abstract:
Objective To evaluate the diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis of mediastinal lymphadenopathy.Methods EBUS-TBNA were performed in 148 mediastinal lymphadenopathy previously by CT were selected,and 129 malignant tumor were confirmed by surgery.The advantages of EBUS-TBNA were evaluated,including superiority,success rate of puncture and diagnostic accurary.Results In 129 cases,mediastinal lymphadenopathy were detected clearly and were guided accurately by EBUS-TBNA.The positive results were obtained in 118 cases,and the false negative results in 11 cases.The success rate of biopsy and sensitivity of diagnosis by EBUS-TBNA in malignant tumor were 100％ and 91.47％ respectively.There were no complications in this group.Conclusions EBUS-TBNA is a safe and useful technique in diagnosis of mediastinal lymphadenopathy and evaluate the response to neoadjuvant chemotherapy.
