Self-Directed Mikoto Simulator Training for Colonoscopy in Gastroenterology Trainees: An International Multicenter Randomized Trial.

New evidencecolonoscopyendoscopy quality
Clinical takeawaySimulator training shows promise as a feasible adjunct to standard colonoscopy training. Although the trial was small (n=12 total) and did not achieve statistical significance for the between-group comparison, the simulator group demonstrated significant within-group improvement in cecal intubation rate from 60.0% to 80.0% (p=0.003) and reduction in procedure time. These findings support using simulation as an educational adjunct in training programs, though larger trials are needed to confirm the magnitude of benefit.
What it foundMikoto simulator training did not significantly improve post-training cecal intubation rate compared to standard training (80.0% vs 77.8%; OR 1.34; 95% CI 0.37-4.84; p=0.606).
ContextSimulation training is widely adopted in GI education with the expectation that it accelerates skill acquisition and improves proficiency. This randomized trial found no additive benefit of self-directed simulator training to standard colonoscopy practice, suggesting supervised hands-on training alone achieves adequate proficiency.
No standard claimed for this paper

Every paper is compared to the standard governing its question. This one is not: either no standard in the corpus matches it, or the comparison did not hold up on review and was withdrawn rather than published unverified. Both are logged.
