Efficacy of endoscopic ultrasonography in evaluation of undetermined etiology of common bile duct dilatation on abdominal ultrasonography

ABSTRACT

Background: The cause of common bile duct [CBD] dilatation cannot be determined by imaging modalities in many patients. The aim of this study was to assess the value of endoscopic Ultrasonography [EUS] in detecting the cause of CBD dilatation in patients in whom Ultrasonography could not demonstrate the cause of dilation
