摘要: Transbronchial needle aspiration (TBNA) offers the unique opportunity to pathologically stage patients with lung cancer at time of diagnostic bronchoscopy. The purpose this study was compare staging sensitivities Wang 22-gauge and 19-gauge needles. We studied 64 bronchogenic carcinoma mediastinal adenopathy. Before bronchoscopy each patient underwent chest CT. Three four aspirates were obtained from endotracheal sites adjacent paratracheal lymphadenopathy. In 47 malignant adenopathy confirmed by needle. A total 29 had aspirates. Of patients, 9 benign, reactive lymph nodes. There 20 in whom only demonstrated malignancy 2 as sole identifier malignancy. As a tool, significantly more sensitive than ne...
