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...

Area of Science:

  • Thoracic Surgery
  • Surgical Education
  • 3D Modeling in Medicine

Background:

  • Bronchial sleeve reconstruction is a complex surgical procedure.
  • Effective training methods are crucial for developing surgical proficiency in this technique.
  • Existing training paradigms may not adequately prepare trainees for the intricacies of sleeve reconstruction.

Purpose of the Study:

  • To develop and evaluate a training program for bronchial sleeve reconstruction.
  • To assess the effectiveness of a 3-dimensional (3D) operable airway model in surgical education.
  • To determine if video-based instructions enhance trainee performance in sleeve reconstruction.

Main Methods:

  • Eight surgical trainees were randomized into a training group (n=4) and a control group (n=4).
  • The training group received 6 cycles of instruction using a 3D operable airway model and video guidance.
  • Surgical performance was assessed by senior surgeons using a 5-point Likert scale, evaluating aspects like airway wall tear, ligatures, needlework, and anastomosis.
  • Anastomosis time was also recorded for both groups.

Main Results:

  • The training program showed a trend towards improved scores in the training group compared to the control group (median 28.2 vs 20.8).
  • Anastomosis time tended to be shorter in the training group post-intervention (median 20.0 vs 24.6 minutes).
  • The reduction in anastomosis time was significantly greater in the training group (median -9.4 minutes, P=.05), indicating improved efficiency.

Conclusions:

  • The developed training program using 3D airway models and video instructions effectively improved surgical trainees' skills in bronchial sleeve reconstruction.
  • This innovative training approach enhances proficiency and potentially reduces operative time.
  • 3D models offer a valuable tool for surgical simulation and education in complex airway procedures.
