Abstract:

Objective The purpose of this study is to explore the hot topics in Web of Science core databasein pediatric liver transplantation from 2016 to 2020. Methods The core database data of Web of Science is download as the data source of this study，and Vosviewer and Citespace softwares were used to visually analyze the published papers，research units，core research authors，journal distribution，research keywords and perform related cluster analysis of pediatric liver transplantation in recent five years. Results A total number of 1 965 articles on pediatric liver transplantation showed that the United States was the main country with 465 articles published in five years, the University of Toronto in Canada was the high publishing institution with 53 articles published, and Mureo Kasahara was the high-yield core author. In the past five years, the high-frequency keywords in the basic research of subject knowledge were "children" "liver transplantation" "outcome" "recipient" and "pedatric", and the high-frequency mutation words include "prognosis" "prophylaxi" "stenosis" and "disorder". Conclusion The research hotspots of pediatric liver transplantation in recent five years include split liver transplantation, clinical changes, acute liver failure in children, brain death, lymphoproliferative disorders, hepatic sinusoidal obstruction syndrome, hepatocellular carcinoma and so on.
