The Use of Endoscopic Ultrasound in the Evaluation of Unexplained Biliary Dilation

Gastrointest Endosc Clin N Am. 2019 Apr;29(2):161-171. doi: 10.1016/j.giec.2018.11.001. Epub 2019 Feb 2.

Abstract

Isolated biliary dilation, as an incidental diagnosis, is increasing owing to an increase in the use of noninvasive abdominal imaging and poses a diagnostic challenge to physicians especially when further noninvasive diagnostic testing fails to reveal an etiology. This article reviews available data describing the natural history of this clinical scenario and the impact of endoscopic ultrasound examination in the evaluation of unexplained dilation of the common bile duct.

Keywords: Abnormal liver tests; Biliary dilation; Endoscopic ultrasound; Magnetic resonance cholangiopancreatography.
