Endobronchial ultrasound (EBUS) is a bronchoscopic technique that uses ultrasound to visualize structures within the airway wall, lung, and mediastinum [1-3]. EBUS is different from endoscopic ultrasound (EUS). While both can visualize and guide sampling of mediastinal lymph nodes, EBUS is performed during bronchoscopy and EUS is performed during gastrointestinal endoscopy.
The indications, contraindications, and complications of EBUS are discussed in this topic review. Types of EBUS, technical aspects of EBUS-guided sampling, and indications for EUS are described separately. (See "Endobronchial ultrasound: Technical aspects" and "Endoscopic ultrasound-guided fine-needle aspiration biopsy in the gastrointestinal tract".)
There are two types of EBUS:
●Radial probe EBUS (RP-EBUS)
●Convex probe EBUS (CP-EBUS)
