Endobronchial ultrasound bronchoscopy: current uses, innovations and future directions
Radial probe endobronchial ultrasound (RP-EBUS) and convex probe EBUS (CP-EBUS) have transformed the approach to diagnosis and management of intrathoracic disease. RP-EBUS, has improved the diagnostic yield of bronchoscopic biopsy of peripheral pulmonary nodules. CP-EBUS is the initial diagnostic tool of choice for mediastinal and hilar lymph node staging of lung cancer. Both EBUS modalities have been used in a variety of novel ways to enhance the minimally invasive diagnostic and treatment capabilities of the bronchoscopist in benign and malignant disease. Thin convex probe EBUS and electromagnetic navigated EBUS are promising advances in endobronchial ultrasound technology that may allow for enhanced diagnostic capabilities in the future. Future research and technological developments will likely continue to expand the application of EBUS in thoracic disease.
