Abstract Hepatic encephalopathy is a common complication of liver cirrhosis. Cognitive dysfunction and abnormal signs of nervous system are the main clinical manifestations, and the fatality rate is relatively high. Currently, the pathogenesis of hepatic encephalopathy is still unclear and specific treatment is lacking. The intestinal microecosystem of patients with hepatic encephalopathy is dysfunctional, and it may induce hepatic encephalopathy by promoting the production of blood ammonia, releasing inflammatory factors, affecting the production of neurotransmitters, and reducing the synthesis of bile acids and short-chain fatty acids. Therefore, the treatment of hepatic encephalopathy based on intestinal flora has become a new entry point, including the use of probiotics, prebiotics, and antibiotics and fecal microbiota transplantation. This review summarizes the main mechanism of action of intestinal flora in hepatic encephalopathy and related treatments based on intestinal flora, in order to provide a new theoretical basis for clinical treatment of hepatic encephalopathy.

Key words： Hepatic encephalopathy Intestinal flora Liver-gut-brain axis Fecal microbiota transplantation
