Chinese expert consensus on laparoscopic hepatic segmentectomy and subsegmentectomy navigated by augmented- and mixed-reality technology combined with indocyanine green fluorescence imaging

Augmented- and mixed-reality technologies have pioneered the realization of real-time fusion and interactive projection for laparoscopic surgeries. Indocyanine green fluorescence imaging technology has enabled anatomical, functional, and radical hepatectomy through tumor identification and localization of target hepatic segments, driving a transformative shift in the management of hepatic surgical diseases, moving away from traditional, empirical diagnostic and treatment approaches toward digital, intelligent ones. The Hepatic Surgery Group of the Surgery Branch of the Chinese Medical Association, Digital Medicine Branch of the Chinese Medical Association, Digital Intelligent Surgery Committee of the Chinese Society of Research Hospitals, and Liver Cancer Committee of the Chinese Medical Doctor Association organized the relevant experts in China to formulate this consensus. This consensus provides a comprehensive outline of the principles, advantages, processes, and key considerations associated with the application of augmented reality and mixed-reality technology combined with indocyanine green fluorescence imaging technology for hepatic segmental and subsegmental resection. The purpose is to streamline and standardize the application of these technologies.
