Conventional TBNA (cTBNA) is a technique used for cytological sampling of mediastinal lymphnodes performed with CT guide, using Wang areas. This method is useful to obtain cytological specimen from lymphnodes and ilo-mediastinal structures for the diagnosis and staging of lung cancer and pulmonary granulomatosis. Since 2003, the spread of EBUS TBNA (Endobronchial Ultrasound-guided Transbronchial Needle Aspiration) has led to a qualitative increase in the cTBNA's yeld due to the better knowledges about vascular structures, studied in real time, and the possibility to sample subcentimetric lymph nodes not reachable with cTBNA. In this study, a retrospective survey was conducted over a period of 24 months to assess, in a U.O. of Interventional Pneumology, the cTBNA diagnostic yield before and during training with EBUS.
