Concomitant gastroparesis negatively affects children with functional gallbladder disease.

Objectives: The aim of the present study was to determine whether concomitant gastroparesis and biliary dyskinesia (BD) occur in children, and if so, to determine whether concomitant gastroparesis affects clinical outcome in children with BD.

Methods: We conducted a retrospective chart review of children with BD (ejection fraction <35% on cholescintigraphy, with no other metabolic or structural cause) who completed a solid-phase gastric emptying scintigraphy scan within 12 months of abnormal cholescintigraphy. Children were classified into 1 of 4 clinical outcome groups (excellent, good, fair, poor).
