HPB Surgery and Oncology


The biliary system refers to the organs that are responsible for producing and storing bile and impacting the digestive and metabolic processes. Bile is a fluid that aids the process of nutrient absorption, digesting fat, and waste removal. The gallbladder stores and concentrates bile, which is a fluid produced in the liver to help digest the fat contained in food. The hepatobiliary system is the liver, gallbladder, bile ducts, and pancreas. Surgical oncology is the broad medical field that uses surgery to treat cancer. Hepato-Pancreato-Biliary procedures are a subspecialty of oncology surgery specific to benign and malignant diseases of the liver, pancreas, and biliary tree. HPB surgery can be complex and requires specialized training and/or experience.
