摘要：目的评价术前三维可视化影像联合术中吲哚菁绿（ICG）荧光显影的多模态可视化教学在肝胆外科本科实习生外科思维培养中的效果与学习体验。方法纳入2020年9月至2021年3月在中山大学附属第六医院肝胆外科实习的本科实习生30名，随机分为经典教学组与三维联合荧光组各15名。两组均采用肝胆外科手术图谱及人民卫生出版社《外科学》教材教学；经典组结合无荧光手术视频；三维联合荧光组增加术前三维可视化讲解、结合术中ICG荧光显影的手术视频及现场手术演示。教学2周，共6学时。结局指标为闭卷考试成绩及Likert 5级量表满意度问卷（学习积极性与自主学习、三维空间理解与应用、应用解剖指导术中决策理解、职业兴趣及总体满意度）。结果两组均完成教学干预。三维联合荧光组闭卷考试成绩高于经典组［（90.2 ± 3.8）分 vs（84.8 ± 2.8）分，P＜0.001］。满意度问卷显示，三维联合荧光组上述各维度评分均高于经典组（均P＜0.001）。结论术前三维可视化影像联合术中ICG荧光显影的多模态可视化教学可显著提升肝胆外科本科实习生知识考核成绩与学习体验，促进由理论解剖向应用解剖转化并强化外科思维与术中决策理解，具有推广价值。
