ABSTRACT
Objective To investigate whether the colonoscopy skills could be retained after the endoscopy simulator training,and to find evidence for curriculum design.Methods A total of 14 trainees received virtual reality simulator colonoscopy training and took a standardized VR colonoscopy test at the end of training and at 6 months later without practice during the time period.Results Scores drastically decreased at 6 months after training when compared to those right after the training.Although there was no difference in safety or accuracy,there was significant difference in the residual air volume,intestinal loop and procedure time.Conclusion Some skills acquired by using the Endoscopy Simulator can be retained,but other skills may be lost,which requires more practice.
