Abstract: Objective To explore the application value of 3D printing combined with PBL in clinical teaching of hepatobiliary surgery residents’ standardized training, taking the liver and liver cancer model as an example. Methods Fifty-six physicians who received residents’ standardized training in hepatobiliary surgery from January 2018 to January 2019 were randomly divided into observation group and control group, 28 in each group. The control group was taught by traditional PBL teaching mode, while the observation group was taught by using 3D technology to print the whole model of liver and liver cancer, and related biliary tract and blood vessel models, and combined with PBL teaching mode. The scores of theoretical examination, CT/MRI image reading ability and teaching satisfaction of the two groups were analyzed. Results The scores of theoretical examination in the observation group were significantly higher than those in the control group (t=4.165, P<0.01); the scores of CT/MRI image reading in the observation group were higher than those in the control group (t=2.922; P<0.01); the students’ satisfaction with teaching in the observation group was significantly higher than that in the control group, and the difference was statistically significant( χ2=4.909, P=0.027). Conclusion 3D printing combined with PBL is an effective teaching method for clinical teaching of hepatobiliary surgery residents’ standardized training, and it is worth popularizing.
