A prospective study of a training program for bronchial sleeve resection using operable 3-dimensional models

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.
