摘要: Intraductal ultrasonography (IDUS) is an imaging modality having unique characteristics and suitable for of a narrow ductal cavity, its wall the neighbouring structures. As IDUS uses high-frequency ultrasound (12-30MHz), image quality very high within approximately 2-cm range radius. The bile duct pancreatic duct, therefore, are good targets assessment by IDUS. Biliopancreatic mainly performed through papilla Vater in same session as endoscopic retrograde cholangiopancreatography (ERCP). Biliary possible percutaneous transhepatic route well. Not many comparative studies on biliopancreatic have been published. Gallbladder well most still at level clinical research. Constant delineation Oddi's sphincter with improvement instruments will expand use lesions.
