Fiber optic bronchoscope

Display of fibrooptic Brochoscope

We are routinely doing fibroptic Brochoscopy both diagnostic and therapeutic on Olympus fibroptic Broncoscope.

A fiber optic bronchoscope is a critical tool in diagnosing and managing chest diseases, allowing direct visualization of the airways and lungs. Below is a concise overview of its role in chest disease, tailored to your query:

Fibro optic bronchoscope

Role in Chest Diseases

  • Diagnostic Applications:
  • Lung Cancer: Visualizes tumors, obtains biopsies (forceps, needle aspiration), or performs bronchial washings for cytology. Fluorescent bronchoscopy detects early-stage lesions.
  • Infections: Identifies causes of pneumonia, tuberculosis, or fungal infections via bronchoalveolar lavage (BAL) or protected brush samples.
  • Interstitial Lung Diseases: BAL and transbronchial biopsies help diagnose sarcoidosis, pulmonary fibrosis, or hypersensitivity pneumonitis.
  • Hemoptysis: Locates bleeding sources (e.g., tumors, bronchiectasis) for targeted intervention.
  • Airway Abnormalities: Assesses tracheal stenosis, bronchomalacia, or foreign body presence.
  • Mediastinal Disorders: Endobronchial ultrasound (EBUS)-guided bronchoscopy samples lymph nodes for staging lung cancer or diagnosing lymphoma.
  • Therapeutic Applications:
  • Foreign Body Removal: Extracts aspirated objects using forceps or baskets.
  • Airway Obstruction: Clears mucus plugs or blood clots in conditions like COPD or atelectasis.
  • Bleeding Control: Instills epinephrine or uses balloon tamponade for hemoptysis.
  • Stent Placement: Deploys stents for airway narrowing due to tumors or scarring.
  • Difficult Intubation: Guides endotracheal tube placement in patients with airway distortion (e.g., from tumors or trauma).
  • Laser Therapy: Delivers laser via bronchoscope to debulk tumors in advanced lung cancer.

Advantages in Chest Disease

  • Minimally Invasive: Performed under local anesthesia with sedation, reducing risks compared to surgical alternatives.
  • Real-Time Visualization: Flexible tip (180° up, 130° down angulation) navigates complex bronchial anatomy.
  • Versatility: Combines diagnostic (biopsy, BAL) and therapeutic (stenting, foreign body removal) capabilities in one procedure.
  • Outpatient Setting: Often done bedside or in endoscopy suites, minimizing hospital stays.

Specific Chest Conditions Addressed

  • Chronic Obstructive Pulmonary Disease (COPD): Assesses airway inflammation, clears secretions, or guides bronchial thermoplasty.
  • Bronchiectasis: Evaluates extent, collects samples to identify pathogens.
  • Pulmonary Alveolar Proteinosis: Performs whole-lung lavage to remove surfactant buildup.
  • Asthma: Investigates severe cases or guides bronchial thermoplasty for refractory asthma.

Procedure Details

  • Setup: Flexible fiber optic bronchoscope (5.0-6.0 mm for adults, smaller for pediatrics) with light source (LED/halogen) and working channel (1.2-3.2 mm for suction/biopsy).
  • Anesthesia: Lidocaine (spray or liquid) for airway numbing; sedation (midazolam, fentanyl) for comfort.
  • Duration: 15-60 minutes, depending on complexity (e.g., biopsy vs. simple inspection).
  • Risks: Rare but include bleeding, pneumothorax (with biopsy), or transient hypoxia.

Limitations

  • Image Quality: Inferior to videobronchoscopes (which use CCD/CMOS chips).
  • Fragility: Fiber optic bundles can break, requiring costly repairs.
  • Learning Curve: Requires skilled operators for complex interventions like EBUS or laser therapy.
