Resumo

The study was aimed to the assessment of the feasibility of the use of endobronchial ultrasound (EBUS-TBNA) for the diagnosis of peribronchial neoplasms of lungs and mediastinal organs. The examination was conducted using convex ultrasound bronchoscope or ultrasonic mini-sensors with subsequent fine-needle aspiration biopsy and biopsy with «Essen» forceps. The use of EBUS-TBNA allowed to make the correct diagnosis in 152 (83.0%) of 183 cases. Mini-sensor and convex bronchoscope had similar performance: 84.6 and 81.7%, respectively (p=0.89, χ2 test). Depending on the location, the best diagnostic results were obtained regarding to 7th zone of lymph nodes - 35 (94.6%) of 37 cases; 2R zone was the most difficult area - 8 of 16 cases (50%, p=0.003, X2 test). 3 (1.6%) patients experienced mild bleeding to the extent of 50 ml during the procedure. 2 (1.1%) patients experienced slight subcutaneous emphysema in the neck during the first days after a biopsy of 2nd zone lymph nodes using forceps. Deaths were not registered. It is emphasized that EBUS-TBNA is effective method of sampling of peribronchial lungs and mediastinal tumors for cytological and histological examination, and it has advantages over other methods of verification of such tumors.
