Endoscopic ultrasound is a minimally invasive imaging modality that provides high - resolution images of the extrahepatic biliary tree and the surrounding structures. It has been shown to be accurate for the detection and staging of bile duct and gallbladder cancer, and is especially useful for small tumors. Intraductal techniques, which are still in evolution, may provide even more information about the etiology and extent of biliary structures and mural tumors. EUS has also been shown to be useful for the detection of biliary stones and sludge when transabdominal ultrasound is not diagnostic. In many cases, diagnostic EUS is needed. 1, 2, 3 Endosonography produces detailed images of the pancreas and surrounding blood vessels and provides both accurate detection and staging of malignant lesions and the means for making a tissue diagnosis.The instruments and techniques for endosonography continue improving, and at present EUS can be considered a promising minimally invasive tool for evaluating the pancreatobiliary disorders. 4, 5
