Global trends of indocyanine green fluorescence navigation in laparoscopic cholecystectomy: bibliometrics and knowledge atlas analysis.

BACKGROUND: Indocyanine green fluorescence cholangiography is a new type of cholangiography that has emerged in recent years. It has many advantages, such as simplicity, safety, and efficiency, and is expected to become a routine procedure for intraoperative cholangiography in the future. However, there is no bibliometric analysis of horizontal generalization in this field. Therefore, this study aims to assess the current research status and developmental trends in this field from a global perspective and to help guide the focus of future research. METHODS: This study was conducted by retrieving the literature related to ICG fluorescence cholangiography published in English from 2000 to 2021 from Web of Science. The Histcite. Pro tool was used to analyze the bibliometric indicators, and VOSviewer was used to visualize the research trends and hotspots in this field. RESULTS: 192 related studies were finally included. For the past 20 years, the number of related publications in this field have increased yearly, with 2010 being a breakthrough point for research in this field. Research has developed rapidly since 2013 and may continue to expand in the next several years. The USA and Japan play leading roles in this field. "SURG ENDOSC", "SURG INNOV", and "J LAPAROENDOSC ADV S" are core journals that publish high-quality literature and the latest developments in this field. Some authors who have a large number of high-quality publications include Ishizawa T and Kokudo N. The current research hotspots in this field are focused on exploring the factors that affect ICG cholangiography and optimization measures. CONCLUSIONS: In general, the number of documents related to ICG fluorescence cholangiography is growing rapidly, with the USA and Japan being influential countries and China being one of the major producers of these documents. The optimization of this new technology will affect key developments in future research.
