BRONCHOSCOPY

n. (Medicine) examination performed with a bronchoscope (tube for examining the bronchi)

Bronchoscopy is a medical procedure where a tube is inserted into the airways, usually through the nose or mouth. This allows the practitioner to examine inside a patient's airway for abnormalities such as foreign bodies, bleeding, tumors, or inflammation. The practitioner often takes samples from inside the lungs: biopsies, fluid (bronchoalveolar lavage), or endobronchial brushing. The practitioner may use either a rigid bronchoscope or flexible bronchoscope.
