Abstract

US and EUS play an important role in the diagnosis of biliary cancer. Especially, EUS is positioned as a modality for in-depth examination diagnosing T factor (TNM classification). In 2013, general rules for clinical and pathological studies on cancer of the biliary tract (The 6th edition: edited by Japanese Society of Hepato-Biliary-Pancreatic Surgery) was modified and proposed as it was consistent with TNM classification (The 7th edition). I discussed here how US and EUS served in the diagnosis of biliary cancers (bile duct cancer, gallbladder cancer and cancer of ampulla of Vater.) in this situation.
