Abstract：Objective To explore the application effect of the novel ex vivo porcine model for pediatric intussusception air enema simulation training.Methods A simple ex vivo porcine colonic intussusception model was constructed to simulate the entire procedure of pediatric intussusception air enema reduction.Participants included five senior physicians and five residents in the Radiology Department.The model simulation,effectiveness and satisfaction were assessed,and the difference in participants'self-confidence before and after training was comparatively analyzed.Results Ten physicians participated and completed this training,scoring(4.62±0.42)on the overall model simulation and effectiveness of training,and as the number of simulation training sessions increased,the participants'operating time lengths were all shorter,while the pressure of air enema,the number of film frames taken and the DAP of fluoroscopic radiation were all lower(P<0.05).The difference in residents'self-confidence assessment scores before and after training was statistically significant(P<0.05).Conclusion This simple novel ex vivo porcine model has good simulation,and can effectively improve radiology residents'air enema reduction skills.
