Olympus EndoTherapy Peripheral Bronchoscopy Procedure

Overview

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

Treatment

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

For lesions that are difficult to locate with traditional bronchoscopy, Olympus’ Guide Sheath Kit functions as an extended working channel beyond the reach of the bronchoscope, through which devices can be exchanged in order to facilitate the convenient transfer of devices for repeated sampling of a peripheral lesion.

Guide Sheath Kit—accessing lesions that reside in the periphery has been a challenge with traditional bronchoscopy. The Guide Sheath Kit has been designed to increase diagnostic yield of peripheral lesions, by acting as an extended working channel, allowing the physician to sample a lesion beyond the reach of the bronchoscope, after confirming the location of the lesion through ultrasound. After the guide sheath is inserted, endobronchial ultrasound probes are inserted through the guide sheath to help locate and identify a lesion, deep within the lungs. Once the lesion is located, the ultrasound probe is removed and sampling devices are introduced into the guide sheath to perform sampling of the lesion in a less invasive, more efficient, and more reliable way. The Guide Sheath Kit enables physicians to easily target peripheral lesions and allows for multiple approaches to one target site. Perhaps the most important benefit of this procedure is that the diagnosis is obtained in a minimally invasive manner, and in those cases where the lesion is found as benign, the patient has been saved from undergoing a more invasive, more costly procedure such as surgery.
