Abstract

Evaluation methods for asymptomatic patients with evidence of dilatation of the main bile duct, pancreatic duct, or both ducts simultaneously are currently not well established. There are no guidelines, at present, to direct us on what is the best choice for the correct assessment of this group of patients. Endoscopic ultrasound has demonstrated outstanding performance in addressing the pancreatobiliary, mainly malignant, disease. This review article presents current evidence on the diagnostic performance of endoscopic ultrasound in asymptomatic patients with signs of dilation of the main bile duct, the main pancreatic duct, or both, in different imaging studies.
