Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) of the liver is a safe procedure in the diagnosis and staging of hepatobiliary malignancies with a minimal major complication rate. EUS-FNA is useful for liver lesions poorly accessible to other imaging modalities of the liver. EUS-guided FNA of biliary neoplasia and malignant biliary stricture is superior to the conventional endoscopic brushing and biopsy.
Core tip: The present article reviews the usefulness of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in patients with focal liver and biliary tract lesions. We conducted MEDLINE search using the terms “endoscopic ultrasound-guided fine needle aspiration”, “focal liver lesions” and “biliary tract lesions”, “EUS and biliary stricture”, EUS and focal liver mass”, “EUS and cholangiocarcinoma” and “EUS and gallbladder” to retrieve articles published between 1999 to 2014.
