Background and study aims: Prior research supports the validity of performance measures derived from the use of a physical model colonoscopy simulator– the Kyoto Kagaku Colonoscope Training Model (Kyoto Kagaku Co. Ltd., Kyoto, Japan) – for assessing insertion skill. However, its use as a training tool has received little research attention. We assessed the efficacy of a brief structured program to develop basic colonoscope insertion skill through unsupervised practice on the model.

Participants and methods: This was a training study with pretesting and post-testing. Thirtytwo colonoscopy novices completed an 11-hour training regime in which they practiced cases on the model in a colonoscopy simulation research laboratory. They also attempted a series of test cases before and after training. For each outcome measure (completion rates, time to cecum and peak force applied to the model), we compared trainees’ post-test performance with the untrained novices and experienced colonoscopists from a previously-reported validation study.

Results: Compared with untrained novices, trained novices had higher completion rates and shorter times to cecum overall (Ps< .001), but were out-performed by the experienced colonoscopists on these metrics (Ps< .001). Nevertheless, their performance was generally closer to that of the experienced group. Overall, trained novices did not differ from either experience-level comparison group in the peak forces they applied (P> .05). We also present the results broken down by case.

Conclusions: The program can be used to teach trainees basic insertion skill in a more or less selfdirected way. Individuals who have completed the program (or similar training on the model) are better prepared to progress to supervised live cases.
