目的:探讨采用三维可视化技术的以案例为基础的学习（case-based learning，CBL）教学法在肝胆外科住培带教中的应用效果。方法:选取2015年1月和2016年12月在徐州医科大学附属淮安医院肝胆外科参加住培的46名学员作为研究对象，分为对照组（n n=22）和试验组（n n=24），分别应用传统教学法及采用三维可视化技术的CBL教学法。在培训结束后，分别对两组进行理论知识和临床技能考核。用问卷调查来评价教学效果。n 结果:试验组学员的理论知识及临床技能考核优于对照组学员[（85.2±5.9）vs.（81.2±5.6），（85.0±5.8）vs.（81.4±3.9）]。问卷调查显示，试验组学员对采用三维可视化技术的CBL教学法总满意度高于对照组学员（95.8% vs. 72.7%）。结论:采用三维可视化技术的CBL教学法值得在住培带教中推广应用。“,”Objective:To explore the application effect of case-based learning (CBL) teaching model on the clinical teaching of standardized residency training of hepatobiliary surgery.Methods:The study selected 46 residents as the research objects who attended the standardized residency training program from January 2015 to December 2016. All the residents were randomly divided into control group (n n=22) using the traditional teaching method and experimental group (n n=24) using CBL teaching method. After the training, the teaching effect was evaluated by the assessment of theoretical knowledge and clinical skills and questionnaire survey between the two groups.n Results:The theoretical knowledge and clinical skills of the residents in the experimental group were significantly better than those in the control group after training [ (85.2±5.9) vs. (81.2±5.6) , (85.0±5.8) vs. (81.4±3.9) ]. The questionnaire survey showed that the total satisfaction of the experimental group with CBL teaching method combined with 3D visualization technology was significantly higher than that of the teaching method of the control group (95.8% vs. 72.7%) .Conclusion:The CBL teaching method with 3D visualization technology is worth popularizing and applying in the education of standardized residency training.
