title: The Efficacy of a Newly Designed, Easy-to-Manufacture Training Simulator for Endoscopic Biopsy of the Stomach.
abstract: OBJECTIVE
  We developed a new endoscopic biopsy training simulator and determined its efficacy for improving the endoscopic biopsy skills of beginners.
  
  
  METHODS
  This biopsy simulator, which presents seven biopsy sites, was constructed using readily available materials. We enrolled 40 participants: 14 residents, 11 first-year clinical fellows, 10 second-year clinical fellows, and five staff members. We recorded the simulation completion time for all participants, and then simulator performance was assessed via a questionnaire using the 7-point Likert scale.
  
  
  RESULTS
  The mean times for completing the five trials were 417.7±138.8, 145.2±31.5, 112.7±21.9, and 90.5±20.0 seconds for the residents, first-year clinical fellows, second-year clinical fellows, and staff members, respectively. Endoscopists with less experience reported that they found this simulator more useful for improving their biopsy technique (6.8±0.4 in the resident group and 5.7±1.0 in the first-year clinical fellow group). The realism score of the simulator for endoscopic handling was 6.4±0.5 in the staff group.
  
  
  CONCLUSIONS
  This new, easy-to-manufacture endoscopic biopsy simulator is useful for biopsy training for beginner endoscopists and shows good efficacy and realism.
