Core tip:Helicobacter pylori (H. pylori) is generally regarded as the risk factor of the development of gastric diseases, including cancer. However, some authors suggest that H. pylori infection can cause other disorders, including liver diseases such as non-alcoholic fatty liver diseases, non-alcoholic steatohepatitis, liver fibrosis, cirrhosis and hepatic carcinoma. The importance of other Helicobacter species in the development of hepatobiliary diseases is also considered. This review examines the current knowledge on the impact of H. pylori infection on the pathogenesis of liver and biliary diseases and considers various points of view.
