Abstract: Objective To explore the value of vitro animal model for endoscopic training for the postgraduates of digestion. Methods　13 postgraduates learned the theory of endoscopic skills and completed a questionnaire firstly. Then they were randomized to receive endoscopic training either on the vitro animal (group B) or on training experience (group A) for 6 months of the clinical observation. At last, one case was assessed by a blinded expert. The total scores, operating time and complications were recorded. All postgraduates completed the questionnaire once again. Results　There were no difference between the two groups in total time, total scores and confidence of endoscopic polypectomy. For EMR, group B spent significantly less time than group A (P<0.05) and had more confidence. For ESD, the total time of group B and group A are (48.9±19.0)min and (88.8±27.8)min respectively. Complications were recorded. There were significant differences between the two groups, especially on marking time, cutting time and dissection time (P<0.05), but there were no difference on injection time. The confidence level of group B (2.9±0.7) was significantly higher than that of group A (1.5±0.5) (P<0.05). There was no perforation in the two groups. For group B, their knowledge of technical and equipment principle of endoscopy and their confidence had been obviously increased after the endoscopic training on vitro animal model. Conclusion　Theory combined with endoscopic training on vitro animal model can make the postgraduates familiar with and master the basic theory and endoscopic skills.
