User, expert and construct validation of a new colonoscopy simulator: correlation with National Endoscopy Database Key Performance Indicators (Science Direct)

A new colonoscopy simulator from RZero Inc. (Mikoto™) is showing promise in training future endoscopists. Validated against the UK’s National Endoscopy Database KPIs, the simulator provides real-time feedback on performance and patient comfort, generating a single score (MSS). In trials with 20 endoscopists, MSS strongly correlated with adenoma detection rate, caecal intubation, and comfort scores. Early results suggest Mikoto™ could become a powerful training tool—bridging the gap between simulation and real-world colonoscopy outcomes.
