Olympus EndoTherapy Transbronchial Needle Aspiration 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.

One common method for taking a biopsy is with Transbronchial Needle Aspiration (TBNA). TBNA is a procedure used to provide a diagnosis of malignant or benign conditions and staging of lung cancer. This is a diagnostic procedure that allows biopsies to be taken from lymph nodes, which are located beyond the endobronchial wall, using the method of needle aspiration. This procedure is frequently performed with the aid of ultrasound.

Indications:

  • Lung cancer staging
  • Sampling endobronchial lesions for a submucosal condition where standard forceps cannot be used to obtain a sufficient sample
  • Diagnosis or staging of mediastinal or hilar adenopathy (swollen lymph nodes)
  • Diagnosis of endobronchial (inside bronchi) lesions with necrotic tumor, hemorrhagic tumor, predicting line of surgical resection
  • Follow up of small-cell tumors, lymphoma (cancerous lymph node)
