Specialized medical specialties that address the diagnosis, treatment, and management of diseases affecting the liver, pancreas, and biliary system include hepatology and hepato-pancreato-biliary (HPB) surgery. Diseases involving the liver, pancreas, and biliary system are diagnosed, treated, and managed in conjunction with the related specialties of hepatology and HPB surgery. Hepatologists concentrate on medicinal treatment and liver transplantation, whereas surgeons with expertise in hemorrhagic–pancreatic illnesses perform surgical procedures. These two disciplines work together to offer patients with hepatobiliary and pancreatic diseases full care.
