摘要
目的:探讨基于虚拟现实(virtual reality，VR)的增强现实(augmented reality，AR)技术在肝胆胰外科教学中的应用效果。方法:选取2021年5月至2022年5月解放军总医院第一医学中心肝胆胰外科医学部规培研究生100名作为本次教学研究对象，按照随机数字表法将学生分成试验组(50名)和对照组(50名)。其中对照组学生采用传统的教学模式，试验组采用基于VR的AR技术进行教学，使用教学评估量表对两组学生的教学指标(基础理论知识、生理解剖、临床思维能力)进行评估对比，对两组学生的临床操作技能进行评价，并采用问卷调查表评价两组教学效果满意度。结果:两组考核成绩评分显示，试验组在基础理论知识、生理解剖、临床思维能力方面均优于对照组(P<0.05)，总成绩明显高于照组(P<0.05)。通过对比得出，试验组学生的各项临床操作技能评分均高于对照组(P<0.05)。问卷调查显示，试验组学生在提高肝胆胰外科学习兴趣、临床实践能力、检索和查阅文献能力及理论应用临床能力等方面评分均高于对照组(P<0.05)，差异均有统计学意义。结论:肝胆胰外科的教学难度相对较大，基于VR的AR技术教学模式在临床教学中具备独特优势，能够显著提升教学效果，进一步提高医学生的专业理论水平和临床实践技巧，并能够培养学生良好的学习兴趣和临床思维能力，值得借鉴参考。
Abstract
Objective:To explore the application effect of augmented reality (AR) technology based on virtual reality (VR) in the teaching of hepatobiliary surgery.Methods:A total of 100 graduate students from the Department of Hepatobiliary Surgery in our hospital from May 2021 to May 2022 were selected as the teaching research objects, and were divided into experimental group (50 students) and control group (50 students) according to the random number table method. The control group adopted the traditional teaching mode, and the experimental group adopted the augmented reality technology based on virtual reality for teaching. The teaching evaluation scale was used to evaluate and compare the teaching indicators of the two groups of students, including basic theoretical knowledge, physiological anatomy and clinical thinking ability. The clinical operation skills of the two groups of students were evaluated and the satisfaction of the teaching effect of the two groups was evaluated by questionnaire.Results:The test scores of the two groups showed that the experimental group was superior to the control group in basic theoretical knowledge, physiological anatomy and clinical thinking ability (P< 0.05), and the total score was significantly higher than the control group (P< 0.05). The results showed that the scores of clinical operation skills of experimental group were higher than those of control group (P< 0.05). According to the questionnaire survey, the scores of students in the experimental group were higher than those in the control group in terms of improving their interest in hepatobiliary surgery, clinical practice ability, literature retrieval ability and theoretical application ability (P< 0.05), and the differences between the two groups were statistically significant.Conclusions:The teaching of hepatobiliary surgery is relatively difficult. The teaching mode of augmented reality technology based on virtual reality has unique advantages in clinical teaching, which can significantly improve the teaching effect, further improve the professional theoretical level and clinical practice skills of medical students, and cultivate students' good learning interest and clinical thinking ability, which is worthy of reference.
