Hepatic ischemia-reperfusion injury (HIRI) is a complex pathological phenomenon dominated by the innate immune system and involves a variety of immune cells. This condition frequently occurs during hepatectomy, liver transplantation or hemorrhagic shock. HIRI represents an important factor in the poor prognosis of patients after liver surgery. However, there is still a lack of effective intervention to reduce the incidence of HIRI. In this study, we aimed to describe the overall structure of scientific research on HIRI over the past 20 years and provide valuable information and guidelines for future researchers. Bibliometric analysis was used to comprehensively review developments in HIRI and changes in our understanding of HIRI over the past two decades. We identified a total of 4267 articles on HIRI that were published over the past 20 years of which basic research was predominant. Collaboration network analysis revealed that China, the University of California Los Angeles, and Ronald W Busuttil were the most influential country, institute, and scholar, respectively. Co-occurrence cluster analysis revealed that ischemic preconditioning, liver cirrhosis, hepatic I/R injury, autophagy, acute liver failure, oxygen, donation after circulatory death, Nlrp3, remote organ, and microdialysis were the top 10 clusters. Keyword burst detection indicated that autophagy, inflammation, and early allograft dysfunction represent the current research hotspots. In summary, this is the first bibliometric analysis of HIRI research. Our timely analysis of these hotpots and research trends may provide a framework for future researchers and further promote research on the key mechanisms and therapeutic measures in this field.
