Endobronchial ultrasound: what is it and when should it be used?
Endobronchial ultrasound has become increasingly used in the UK as a lung cancer staging and diagnostic tool. It has many applications especially in the mediastinal lymph nodes but also the vascular structures as well as the airway wall itself. It is superior to conventional transbronchial needle aspiration in lung cancer staging and diagnosis of mediastinal lymphadenopathy. With time it may well replace mediastinoscopy completely for staging lung cancer. There are, however, training issues and revenue-based tariff systems have been slow to reflect this innovation. Future developments may include routine use in the assessment of central pulmonary vasculature and assessment of airway wall remodelling.
