Prediction of symptom improvement in children with biliary dyskinesia.

Background: Rates of cholecystectomy for biliary dyskinesia are rising. Our objective was to identify clinical determinants of symptom improvement in children undergoing cholecystectomy for biliary dyskinesia.

Methods: This retrospective cohort study included patients undergoing cholecystectomy for biliary dyskinesia from 2006-2013 who had their gallbladder ejection fraction (EF) measured by either cholecystokinin-stimulated hepatobiliary iminodiacetic acid scan and/or fatty meal ultrasound.
