The use of one single echoendoscope in both the trachea and the oesophagus in diagnosing and staging of lung cancer

The use of one single ultrasound echoendoscope in both the trachea (EBUS) and the oesophagus (EUS-B) gives a fast, safe and precise diagnosis and stage of the patient with suspected lung cancer. There is solid evidence for simulator-based training in EBUS concerning safety and diagnostic outcome, but this is currently not an option in EUS-B and needs development. In this review, we recommend evidence-based simulator training and certification in EBUS and when available also in EUS-B before practicing on patients.
