AB  - BACKGROUND: The reperfused human cadaver is a validated simulator for surgery. We 
      aimed to use it as a colonoscopy simulator. METHODS: Novices, intermediates and 
      skilled participants in gastrointestinal endoscopy were included. They performed 
      one colonoscopy on a reperfused human cadaver and reaching rates, time, and 
      length needed to reach anatomical landmarks were reported for construct validity 
      analysis. We also assessed our model realism (SRS survey), educational content 
      (CVS survey) and task load (NASA-TLX index). Score items were collected and 
      defined as "favorable" when items were rated >/= 5/7 with an inter-quartile range 
      (IQR) overlapping four, and "very favorable" when rated >/= 5/7 with an IQR 
      excluding four (neutral). Primary endpoints were the rectosigmoid junction (RSJ) 
      reaching rate and the descending colon (DC) reaching time. Secondary objectives 
      were SRS, CVS and NASA-TLX questionnaire results. RESULTS: A total of 11 skilled 
      participants, 5 intermediates and 8 novices were included. Skilled participants 
      reached RSJ more often than novice and intermediary groups, respectively, 100%, 
      80% and 75% without differing significantly. They reached DC more frequently 
      (100% for skilled, 80% for intermediates and 50% for novices, p = 0.018). The 
      median time to reach RSJ (59, 272 and 686 s for skilled, intermediates and 
      novices group, respectively) and DC (90, 534 and 1360 s for skilled, 
      intermediates and novices) was significantly shorter for skilled participants 
      (both p < .01). Nineteen out of the 22 items composing the realism survey 
      obtained "very favorable" and "favorable" scores. Educational content was 
      designated as "very favorable". Mental, physical, and technical demands were 
      gradually higher the lower the initial level of experience. CONCLUSIONS: 
      Reperfused human cadaver model has the potential to be valid simulation tool for 
      diagnostic colonoscopy training.
