Abstract
Objective To explore the diagnostic value of transbronchial needle aspiration ( TBNA ) for pulmonary or mediastinal lesions.Methods Fifty - six patients with enlarged mediastinal lymph nodes underwent routine fiberoptic bronchoscope examinations, which revealed no ohvious lumps inside the cavity nor pressure from outside the bronchial cavity.Transbronchial needle aspiration was carried out in these patients, with subsequent brush cytology performed at the TBNA site.Additional biopsy were carried out when thickened local mucosa, congestion or edema were seen.Positive rates of diagnosis of TBNA and bronchoscopy brush cytology combined with mucosa biopsy were compared to evaluate the validity and safety of TBNA,with its possible influencing factors analyzed.Results Of the 56 cases with mediastinal lymphonode enlargement, 34 were diagnosed by TBNA, with the diagnostic rate ( 60.7％ ) higher than that of hronchoscopy hrush cytology comhined with mucosa hiopsy ( 16.1％ )( P ＜0.01 ).The influencing factors included size and site of the examined lymph nodes.Lymph nodes larger than 2 cm in diameter delivered higher positive rates of TBNA diagnosis ( P ＜ 0.01 ).Mediastinal lymph nodes in group seven delivered higher positive rates than those in the other groups ( 76.9％ vs.46.7％ ) ( P ＜ 0.05 ).Complications of TBNA were rare,mostly slight bleeding of the puncture site.Conclusion TBNA is a safe and effective method in the diagnosis of lesions outside the bronchial cavity or enlargement of mediastinal lymph nodes and lymph nodes within the hilum of the lungs , especially when the bronchi are unobstructed.关键词
