Abstract：Objective To explore the application effect of problem-based learning and case-based learning combined with Three-Dimensional visualization technology in hepatobiliary surgery teaching. Methods A total of 68 clinical medical students enrolled in Shanghai East Hospital of Hepatobiliary Surgery from January to September 2021 were selected as the experimental subjects of this study. The students were divided into experimental group and control group by digital random table, with 34 cases in each group. The control group adopted the traditional teaching mode, while the experimental group adopted the new teaching method of problem-based learning and case-based learning combined with Three-Dimensional visualization technology. The teaching indexes of the two groups were compared by teaching scale evaluation method: theoretical achievement, anatomical achievement and total achievement, and also clinical practice skills were scored. Results The anatomical scores and total scores of the experimental group were higher than those of the control group, with statistically significant differences (P<0.0001). The scores and total scores of various clinical practice skills of the experimental group were higher than those of the control group, with statistically significant differences (P<0.0001). Conclusion It is difficult to teach hepatobiliary surgery interns, but problem-based learning and case-based learning combined with Three-Dimensional visualization technology can improve the teaching mode, make students master the anatomy of hepatobiliary system more easily, and effectively improve the teaching quality and efficiency.
