[Endobronchial brush biopsy].

Bronchial brushing under fluoroscopy control is used in the diagnosis of pulmonary lesions which are beyond reach of the bronchoscope. A small nylon or steel brush is passed through a bronchial catheter and tissue material from the lesion is taken for cytologic and bacteriologic studies. The technique described is easy to learn, relatively safe, is well tolerated by patients and gives good diagnostic results.
