A novel training device for tip control in colonoscopy: preliminary validation and efficacy as a training tool

Area of Science:

• Medical Simulation
• Gastroenterology Training
• Endoscopic Skill Development

Background:

• Colonoscope tip control is crucial for effective colonoscopy.
• Novice trainees struggle with precise tip control, lacking dedicated training methods.
• A novel training device was developed to address this skill gap.

Purpose of the Study:

• To preliminarily validate a new training device for colonoscopic tip control.
• To assess the device's efficacy in improving novice colonoscopists' skills.

Main Methods:

• Study 1: Experienced endoscopists and novices performed target tracking on training surfaces; performance was compared.
• Study 2: Novices underwent a six-session training program with the device, tested pre- and post-training.
• Outcome measures included completion time and performance variability.

Main Results:

• Experienced endoscopists demonstrated significantly faster and more consistent tip control than novices.
• Novices showed significant improvements in speed and consistency after training.
• Post-training novice performance became comparable to that of experienced endoscopists.
• Improvements generalized to new training surfaces.

Conclusions:

• The training device's performance metrics can differentiate between novice and experienced colonoscopists, supporting its construct validity.
• The device serves as an effective training tool for enhancing fundamental colonoscopy tip control skills.
