Abstract:
Objective:To explore the application effect of mixed reality technology in the teaching of hepatobiliary surgery.
Methods:A total of 120 professional postgraduates majored in surgery who had received the four-month standardized training of residents in hepatobiliary surgery department of the First Affiliated Hospital of Army Military Medical University and the First Affiliated Hospital of Chongqing Medical University during 2016-2018 were selected and were equally allocated into the control group and the research group via random number table method. Students in the control group were trained with traditional surgical teaching mode and in the research group were trained with three-dimensional visualization model which was constructed by mixed reality. Students in both groups received assessment and questionnaires at the end of training.
Results:Scores of theoretical examination and surgical operation assessment of students in the research group were higher than those in the control group (P<0.05). The error rate for separating gallbladder artery and bile duct in the laparoscopic simulated system of students in the research group was significantly lower than that in the control group (P<0.05). Students-teacher satisfaction degree in the research group was higher than that in the control group (P<0.05).
Conclusion:Using mixed reality technology to construct a three-dimensional visualization model and to implement hepatobiliary surgery teaching enables the trainees to better master anatomical key points in the hepatobiliary system and the hepatobiliary surgical approach, with good feedback.
