| 目的 探索混合现实技术在肝胆外科手术教学中的应用效果。方法 选取2016至2018年在陆军军医大学第一附属医院肝胆外科及重庆医科大学附属第一医院肝胆外科接受过住院医师规范化培训4个月的外科学专业学位硕士研究生120例，按照随机数字法均分为对照组和研究组。对照组采用传统手术教学模式，研究组采用混合现实技术构建三维可视化模型实施手术教学，分别在培训结束时对两组学员进行考核及问卷调查。结果 研究组学员理论考试及手术操作考核分数均明显高于对照组学员（P＜0.05）；研究组学员腹腔镜模拟系统操作考核中血管及胆管分离操作步骤出错率明显低于对照组学员（P＜0.05）；研究组学员对教学方法满意度评分及带教教师对学员表现满意度评分明显高于对照组学员（P＜0.05）。结论 应用混合现实技术构建三维可视化模型实施肝胆外科手术教学，能使受训学员更好地掌握肝胆系统解剖要点及手术入路，反馈效果良好。 |

| Objective To explore the application effect of mixed reality technology in the teaching of hepatobiliary surgery. Methods A total of 120 professional postgraduates majored in surgery who had received the four-month standardized training of residents in hepatobiliary surgery department of the First Affiliated Hospital of Army Military Medical University and the First Affiliated Hospital of Chongqing Medical University during 2016-2018 were selected and were equally allocated into the control group and the research group via random number table method. Students in the control group were trained with traditional surgical teaching mode and in the research group were trained with three-dimensional visualization model which was constructed by mixed reality. Students in both groups received assessment and questionnaires at the end of training. Results Scores of theoretical examination and surgical operation assessment of students in the research group were higher than those in the control group (P<0.05). The error rate for separating gallbladder artery and bile duct in the laparoscopic simulated system of students in the research group was significantly lower than that in the control group (P<0.05). Students-teacher satisfaction degree in the research group was higher than that in the control group (P<0.05). Conclusion Using mixed reality technology to construct a three-dimensional visualization model and to implement hepatobiliary surgery teaching enables the trainees to better master anatomical key points in the hepatobiliary system and the hepatobiliary surgical approach, with good feedback. |
