摘要

BACKGROUND: Colonoscopy insertion is difficult to teach due to the inability of current training models to provide realistic tactile sensation with simultaneous three-dimensional (3D) colonoscope display. AIMS: To assess the influence of a simulator consisting of a colon model coupled with 3D instrument visualization on trainee colonoscopy performance. METHODS: Pilot study using the simulator model with three trainees who were not proficient in colonoscopy. At random times over a 6-week period, trainees participated in an individualized half-day session using the Colonoscope Training Model and a colonoscope equipped with a 3D magnetic probe imaging system (ScopeGuide) in six standardized cases. A blinded supervising instructor graded patient-based colonoscopy performance over the 6-week period, and we independently analyzed the 2-week period before and after the intervention. We also measured cecal intubation and withdrawal times and medication requirements. RESULTS: Trainees performed 86 patient-based colonoscopies. Following the intervention, the colonoscopy performance score improved from 4.4 +/- 2.3 to 5.9 +/- 2.4 (p = 0.005). Trainees had a 76% cecal intubation rate following the session as compared to 43% before training (p = 0.004), while utilizing less time, 14 +/- 7 versus 18 +/- 11 min (p = 0.056) and less medication (p > 0.05). CONCLUSIONS: Colonoscopy simulation using the Colonoscope Training Model and the ScopeGuide produced an immediate and large effect on trainee colonoscopy performance.
