目的 探讨模拟训练在进修医师经皮胆道镜取石教学中的应用价值。方法 选取2020年12月至2022年10月在郑州大学第一附属医院肝胆胰外科进修的56名医师,采用随机数字表法将其分为试验组和对照组。试验组28名学员采用模拟训练,对照组28名学员采用传统教学。教学效果评价包括理论考核、胆道镜技能考核和调查问卷。采用t检验和χ²检验比较两组间差异。结果 试验组学员理论考核和胆道镜技能考核成绩高于对照组学员,分别为(84.32±5.79)分比(76.71±6.74)分和(86.89±7.29)分比(77.43±6.42)分,其差异均具有统计学意义(均P＜0.001)。试验组学员比对照组学员在学习兴趣(4.68±0.48)分比(4.32±0.55)分]、学习效率[(4.89±0.32)分比(4.32±0.48)分]、自信心[(4.57±0.50)分比(4.25±0.44)分]、操作能力[(4.75±0.44)分比(4.07±0.47)分]、合作能力[(4.71±0.46)分比(3.96±0.43)]、教学安排合理性[(4.75±0.44)分比(4.25±0.44)分]、整体教学效果[(4.64±0.49)分比(4.21±0.42)分]7个方面满意度高,其差异均有统计学意义(均P＜0.05)。结论 模拟训练有助于提高进修医师经皮胆道镜取石的理论知识及操作技能,并得到进修医师的认可,是一种行之有效的教学方法。

Objective To explore the application of simulation training in the teaching of percutaneous choledochoscopy lithotomy for advanced physicians. Methods Fifth-six refresher doctors who joined the training program of choledochoscopy from December 2020 to October 2022 in the Department of Hepatobiliary and Pancreatic Surgery of The First Affiliated Hospital of Zhengzhou University were randomly divided into experimental group (n=28) and control group (n=28). The experimental group received simulation training, while the control group received traditional teaching. The theoretical assessment, choledochoscopy skill assessment and questionnaire survey were used to evaluate the teaching effect. Using t-test and χ² test to compare the differences between two groups. Results The theoretical assessment and choledochoscopy skill assessment in the experimental group were higher than that in the control group with (84.32±5.79) vs. (76.71±6.74) and (86.89±7.29) vs. (77.43±6.42), respectively, There were all statistical differences (all P＜0.001). The experimental group had a higher scores than those of the control group in learning interest[(4.68±0.48) vs. (4.32±0.55)], learning efficiency[(4.89±0.32) vs. (4.32±0.48)], self-confidence[(4.57±0.50) vs. (4.25±0.44)], operation ability[(4.75±0.44) vs. (4.07±0.47)], cooperation ability[(4.71±0.46) vs. (3.96±0.43)], rationality of teaching arrangement[(4.75±0.44) vs. (4.25±0.44)] and overall teaching effect[(4.64±0.49) vs. (4.21±0.42)] andThere were all statistical differences (all P＜0.05). Conclusions Simulation training is helpful to improve theoretical knowledge and operational skills of refresher doctors in percutaneous choledochoscopy, and is recognized by these trainees. It is an effective method in the teaching of percutaneous choledochoscopy.
