AIM:To evaluate the effect of hands-on training of gastroenterology fellows in gastric polypectomy using an ex vivo simulator.METHODS:Eight gastroenterology fellows at Mackay Memorial Hospital,Taipei were evaluated in gastricpolypectomy techniques using a pig stomach with artificial polyps created by a rubber band ligation device.The performance of four second year(year-2)fellows who had undergone one year of clinical training was compared with that of four f irst year(year-1)fellows both before and after a 4-h workshop using the ex vivo simulator.The workshop allowed for hands-on train-ing in the removal of multiple artif icial polyps and the placement of hemoclips at the excision site.Evaluation included observation of technical skills,procedure time,and the fellows’ conf idence scale.RESULTS:One week after the workshop,the year-1 fellows were re-evaluated and had significantly im-proved mean performance scores(from 17.9 ± 1.8 to 22.5 ± 0.7),conf idence scale(from 4.5 ± 1.0 to 7.8 ± 0.5)and procedure time(from 615.0 ± 57.4 s to 357.5 ± 85.0 s)compared with their baseline performance.After 4 h of training using the ex vivo simulator,the skills of the year-1 fellows were statistically similar to those of the year-2 fellows.CONCLUSION:Use of this ex vivo simulator significantly improved the endoscopic gastric polypectomy skills of gastroenterology fellows who had not had previous clinical training in gastric polypectomy.
AIM: To evaluate the effect of hands-on training of gastroenterology fellows in gastric polypectomy using an ex vivo simulator. METHODS: Eight gastroenterology fellows at Mackay Memorial Hospital, Taipei were evaluated in gastricpolypectomy techniques using a pig stomach with artificial polyps created by a rubber band ligation device. The performance of four second year (year-2) fellows who had undergone one year of clinical training was compared with that of four of f first year (year-1) fellows both before and after a 4-h workshop using the ex vivo simulator. The workshop allowed for hands-on train-ing in the removal of multiple artificial polyps and the placement of hemoclips at the excision site. Evaluation included observation of technical skills, procedure time, and the fellows’ conf idence scale. RESULTS: One week after the workshop, the year-1 fellows were re-evaluated and had significantly im-proved mean performance scores (from 17.9 ± 1.8 to 22.5 ± 0.7), conf idence scale (from 4.5 ± 1.0 to 7.8 ± 0.5) and procedure time (from 615.0 ± 57.4 s to 357.5 ± 85.0 s) compared with their baseline performance. After 4 h of training using the ex vivo simulator, the skills of the year-1 fellows were arrested similar to those of the year-2 fellows.CONCLUSION: Use of this ex vivo simulator significantly improved the endoscopic gastric polypectomy skills of gastroenterology fellows who had not had previous clinical training in gastric polypectomy.
