Abstract
In recent years, the combination of endobronchial ultrasound and endoscopic ultrasound has enabled "medical exploration" of the mediastinum for the study of mediastinal lymphadenopathies. These techniques are particularly important for the diagnosis and staging of lung cancers. Progress has been made with the availability of new-generation cutting needles for endoscopic ultrasound and new cryobiopsy needles for endobronchial ultrasound to improve the quality of samples.
