Endoscopic Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...

Area of Science:

  • Pulmonary Medicine
  • Medical Robotics
  • Diagnostic Bronchoscopy

Background:

  • Increased incidence of pulmonary nodules (PNs) due to expanded lung cancer screening.
  • Conventional bronchoscopy faces limitations in accessing PNs.
  • Need for advanced tools to improve diagnostic capabilities for PNs.

Purpose of the Study:

  • To evaluate a novel multisection robotic bronchoscope (SR) for accessing pulmonary nodules.
  • To compare the reach and accessibility of the SR against conventional bronchoscopes in a cadaveric model.
  • To assess the potential impact of the SR on lung cancer screening and diagnosis.

Main Methods:

  • Cadaveric assessment involving 3 operators comparing the SR with conventional (OL-6.3) and thin (OL-4.2) bronchoscopes.
  • Primary outcome: number of airway generations traversed from the carina.
  • Secondary outcomes: insertion depth, CT-to-body divergence, and accessible lung parenchyma volume for biopsy.

Main Results:

  • The SR reached significantly greater airway generations (median 6) compared to OL-6.3 (median 4) and OL-4.2 (median 5).
  • SR demonstrated superior performance across all lung lobes and greater insertion depth.
  • This enhanced reach translates to increased access to total and peri-bronchial lung volumes, potentially enabling biopsy of an additional 17,601 nodules annually in the US.

Conclusions:

  • The novel robotic bronchoscope (SR) significantly outperforms conventional bronchoscopes in tracheobronchial tree reach.
  • The SR provides greater access to lung parenchyma for biopsy, addressing limitations of current diagnostic methods.
  • This technology holds promise for improving the diagnostic yield in lung cancer screening programs.
