Abstract: Objective:To study the subject domain knowledge of surgery and liver surgery education using multiple statistical and social network analysis, then to build visualized knowledge-mapping and predict the future development trend.
Methods:Pubmed database was systematically searched using key words “(education, student, general surgery, liver surgery, and hepatobiliary surgery)” from 2010 to 2022. A total of 5157 articles were returned. The co-occurrence matrix was built by the Bicomb. Transformation, dimensionality reduction and clustering of the co-occurrence matrix were analyzed by SPSS 22.0, and visualized network was drawn by Ucinet 6.0.
Results:The visualized domain knowledge-mapping of surgery and liver surgery education was successfully built. By comparing the time periods before and after COVID-19, the current study explored the impact of epidemic situation on surgery and liver surgery education. Computer aided technology and virtual reality technology have become the technical driving force of liver surgery education. At the same time, as a subject that emphasizes clinical practice and operation, the monitoring of teaching quality and the evaluation and certification of training effect have become the key contents of liver surgery education. Moreover, the epidemic situation has brought changes to the education mode of liver surgery.The combination of endoscopic and endoscopic surgery, 3D reconstruction and visualization technology, digital surgery technology and surgical navigation system can further promote the teaching of surgery in the epidemic situation.
Conclusions:A variety of advanced teaching technologies have been applied in surgery education in the epidemic situation. The visualized domain knowledge-mapping has promoted the rapid development of the surgical teaching quality evaluation system, and new teaching technologies are also in urgent need of application in general surgery education.
