To study the application effect of 3D-printed anatomical models combined with laparoscopic surgery videos in the clinical teaching of laparoscopic hepatectomy (LH).

A total of 40 fifth-year undergraduate interns from January 2023 to December 2024 were included as research subjects. They were divided into a traditional group and a combined group using a random number table method, with 20 interns in each group. The traditional group adopted conventional teaching methods, while the combined group used 3D-printed anatomical models combined with laparoscopic surgery videos for teaching. The theoretical test scores, operational skill scores (before and after teaching), students’ recognition of the teaching method, and teaching effectiveness were compared between the two groups.

After teaching, the theoretical test scores and operational skill scores of the combined group were significantly higher than those of the traditional group (P<0.05); the students’ recognition of the teaching method in the combined group was higher than that in the traditional group (P<0.05); the learning interest, understanding of theoretical knowledge, teaching satisfaction, and comprehensive scores of the combined group were all higher than those of the traditional group (P<0.05).

The teaching method of 3D-printed anatomical models combined with laparoscopic surgery videos helps to improve interns’ understanding of LH theoretical knowledge, master operational skills, and enhance their interest in transitioning from theoretical learning to practical learning. It also achieves high teaching recognition and satisfaction.
