Welcome to the new academic journal OBM Hepatology and Gastroenterology. Recent progress in understanding liver, biliary, pancreatic and gastro-intestinal diseases and their treatments has been observed in the world. OBM Hepatology and Gastroenterology publishes interesting and informative reviews, original articles, and invaluable case reports in this area. We also publish basic research as well as clinical research.

Hepatitis A virus (HAV), HBV, HCV, HDV, and HEV are still a serious issue worldwide. Treatments on these viruses have recently improved. However, liver fibrosis, cirrhosis and hepatocellular carcinoma are still critical conditions. We focus on all of these liver diseases. We also focus on broad-spectrum of gastro-intestinal diseases in this journal.

Please accept our special thanks for choosing to publish in the OBM Hepatology and Gastroenterology. We are looking forward to your submissions for OBM Hepatology and Gastroenterology.
