title: Endoscopic simulator curriculum improves colonoscopy performance in novice surgical interns as demonstrated in a swine model.
abstract: BACKGROUND
  The purpose of this study was to determine whether independent virtual endoscopic training accelerates the acquisition of endoscopic skill by novice surgical interns.
  
  
  METHODS
  Nine novice surgical interns participated in a prospective study comparing colonoscopy performance in a swine model before and after an independent simulator curriculum. An independent observer evaluated each intern for the ability to reach the cecum within 20 min and technical ability as determined by Global Assessment of Gastrointestinal Endoscopic Skills--Colonoscopy (GAGES-C) score and performance compared. In addition, at the conclusion of training, a post test of two basic simulated colonoscopy modules was completed and metrics evaluated. As a control, three attending physicians who routinely perform colonoscopy also completed colonoscopy in the swine model.
  
  
  RESULTS
  Prior to endoscopic training, one (11 %) intern successfully intubated the cecum in 19.56 min. Following training, six (67 %) interns reached the cecum with mean time of 9.2 min (p < 0.05). Statistically significant improvement was demonstrated in four out of five GAGES-C criteria. All three experts reached the cecum, with a mean time of 4.40 min. Comparison of expert and post-curriculum intern times demonstrated the experts to be significantly faster (p < 0.05). Comparison of interns who were and were not able to reach the cecum following the simulator curriculum demonstrated significantly improved GI Mentor™ performance in the efficiency (79 vs. 67.1 %, p = 0.05) and time to cecum (3.37 vs. 5.59 min, p = 0.01) metrics. No other significant difference was demonstrated in GAGES-C categories or other simulator parameter.
  
  
  CONCLUSIONS
  Simulator training on the GI Mentor™ alone significantly improved endoscopic skills in novice surgical interns as demonstrated in a swine model. This study also identified parameters on the GI Mentor™ that could indicate 'clinical readiness'. This study supports the role for endoscopic simulator training in surgical resident education as an adjunct to clinical experience.
