Extrabiliary Pathology Identified by Right Upper Quadrant Abdominal Ultrasound in Emergency Department Patients.

Background: The effectiveness of point of care (POC) right upper quadrant ultrasound (RUQ US) in the diagnosis of biliary disease has been well studied. Extrabiliary pathology that might remain undetected in the course of typical, focused POC RUQ US has not been directly examined.

Objectives: Our objective was to determine the prevalence and clinical significance of extrabiliary findings (EBFs) seen on radiology-performed, comprehensive RUQ US.
