The authors sought to determine the diagnostic test characteristics of bedside emergency physician (EP)-performed ultrasound (US) for cholelithiasis in symptomatic emergency department (ED) patients. ⋯ This study suggests that in patients presenting to the ED with pain consistent with biliary colic, a positive EUS scan may be used to arrange for appropriate outpatient follow-up if symptoms have resolved. In patients with a low pretest probability, a negative EUS scan should prompt the clinician to consider an alternative diagnosis.
