The efficacy of training insertion skill on a physical model colonoscopy simulator

Area of Science:

• Medical Simulation
• Surgical Education
• Gastroenterology Training

Background:

• Colonoscopy simulators like the Kyoto Kagaku Colonoscope Training Model are validated for assessing insertion skill.
• The efficacy of these physical models as a training tool requires further investigation.

Purpose of the Study:

• To assess the effectiveness of a brief, structured training program for developing basic colonoscope insertion skills.
• To evaluate skill acquisition through unsupervised practice on a physical colonoscopy simulator model.

Main Methods:

• A training study involving 32 novices with pre- and post-testing.
• Participants completed an 11-hour unsupervised training regime on the Kyoto Kagaku Colonoscope Training Model.
• Performance metrics (completion rates, time to cecum, peak force) were compared to untrained novices and experienced colonoscopists.

Main Results:

• Trained novices demonstrated significantly higher completion rates and shorter times to cecum compared to untrained novices.
• Trained novices' performance approached that of experienced colonoscopists but did not reach their level.
• No significant differences in peak force applied were observed between trained novices and either comparison group.

Conclusions:

• A self-directed training program utilizing the colonoscopy simulator model can effectively teach basic insertion skills.
• Individuals completing this training are better prepared for supervised procedures on live patients.
