Olympus EndoTherapy Endobronchial Ultrasound (EBUS) Procedure


Bronchoscopy is a routine method used for diagnostic and therapeutic procedures performed within the lungs. It allows direct visualization within the lumen of the upper airway and the tracheobronchial tree including subsegmental bronchi. Bronchoscopy allows sampling of the respiration tract secretions and cells, and biopsy of the airway, lung, and mediastinal structures.

Symptoms of Pulmonary Problems

Indications for bronchoscopy can include any of the following:

  • Persistent or unexplained cough, hoarseness, vocal cord paralysis
  • Haemoptysis–coughing up of blood from respiratory tract, generally indicating severe infection
  • Wheezing, shortness of breath
  • Chest pain
  • Evaluation for lung transplant rejection
  • Evaluation for chest or airway trauma
  • Lung cancer diagnosis and staging
  • Positive sputum cytology regardless of a normal chest
  • x-ray
  • Suspected tracheoesophageal fistula
  • Removal of foreign bodies from the lungs

These symptoms may or may not indicate one of the following (this is not a comprehensive list):

  • Tumors
  • Endobronchial lesions indicative of further diagnosis
  • Infection including, but not limited to:
    • Fungal Infections
    • Tuberculosis or mycobacteria
    • Pneumonia
  • Inflammation of the lungs (hypersensitivity pneumonitis)
  • Rheumatoid lung disease
  • Vasculitis
  • Granulomas
    • Sarcoidosis


In order to diagnose a condition or stage lung cancer, a biopsy or sample is taken using biopsy forceps, needle aspiration, or endobronchial brushing.

Endobronchial Ultrasound Transbronchial Needle Aspriation (EBUS-TBNA) is one one method for sampling lymph nodes and nodules under real-time view.  This procedure uses an ultrasonic bronchoscope, specifically designed for diagnostic biopsies and staging in the lung. The scope’s design enables physicians to visualize lymph nodes and surrounding vessels in real-time, via ultrasound, while simultaneously viewing the endoscopic image. The EBUS-TBNA System makes biopsies safer and more accurate than conventional “blind” TBNA and offers a less invasive, less costly alternative to mediastinoscopy.


  • Lung cancer diagnosis and staging
  • Distant metastasis of other known or unknown cancer types
  • Lymphoma (benign or malignant disease of the lymph nodes)
  • Other diseases
    • Tuberculosis
    • Sarcoidosis
    • Histoplasmosis (fungal disease)
