Endoscopic Studies I: Bronchoscopy and Thoracoscopy

796
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...

Area of Science:

  • Medical Education
  • Medical Simulation
  • 3D Printing Technology

Background:

  • Low-fidelity simulation is crucial for mastering complex procedural skills.
  • Developing cost-effective training tools is essential for medical education.
  • Traditional simulators can be expensive, limiting accessibility.

Purpose of the Study:

  • To develop and evaluate a novel, low-cost bronchial tree simulator using 3D-printing technology.
  • To compare the anatomical realism of the 3D-printed simulator against existing commercial models.
  • To assess the simulator's effectiveness in training specific bronchoscopy procedures.

Main Methods:

  • A bronchial tree simulator was created using 3D-printing technology from human thorax CT scans.
  • Thirty experienced physicians participated in a randomized, single-blind study.
  • Participants used a fiberoptic bronchoscope to rate simulator realism using a visual analogue scale (VAS) for specific tasks and overall realism.

Main Results:

  • The 3D-printed simulator was rated significantly more realistic for localizing the right upper lobe bronchial lumen (p = 0.002).
  • No significant differences were found in bronchial blocker placement (p = 0.792) or fluid aspiration (p = 0.057) realism.
  • The 3D-printed simulator achieved higher overall realism ratings (p = 0.021) compared to commercial alternatives.
  • The cost of the 3D-printed simulator was substantially lower (£85 vs. >£2000).

Conclusions:

  • The 3D-printed bronchial tree simulator is a realistic and inexpensive alternative for bronchoscopy training.
  • It provides a valuable tool for practicing procedures on patient-specific models.
  • This technology has the potential to enhance medical training accessibility and effectiveness.
