Endobronchial Ultrasound

What is EBUS?

EBUS is a minimally invasive means of achieving fine needle aspirate biopsy of mediastinal lymph nodes and masses, and biopsy of peripheral pulmonary nodules, under direct ultrasound visualisation/guidance. It is a significantly less invasive means of sampling when compared to traditional surgical mediastinoscopy.


Indications for EBUS could include (but are not limited to):

  • Mediastinal staging of lung cancer
  • Diagnosis of lung cancer
  • Investigation of mediastinal adenopathy of uncertain cause
  • Diagnosis of sarcoidosis
  • Diagnosis of lymphoma
  • Diagnosis of metastatic malignant lymphadenopathy
  • Diagnosis of peripheral pulmonary nodules/masses

EBUS is usually performed as a day procedure, with return home within a few hours.
