Upper GI series in infants and children with vomiting: insights into ACR appropriateness criteria

Abstract

Background: Although upper gastrointestinal series (UGI) series are frequently requested in pediatric radiology department, there are few articles investigating its value in children with vomiting. The purpose of this study was to review imaging findings perceived during UGI series in infants and children presented with vomiting in correlation to their symptoms based on the ACR appropriateness criteria. This was to identify clinical scenarios with higher diagnostic yield. Results: A cross-sectional study including UGI series of 76 patients presented with vomiting (1 month–17 years) was performed. Patients were grouped according to their age into 5 groups and stratified according to the type of vomiting into 3 groups (bilious vomiting, new-onset nonbilious vomiting, intermittent nonbilious vomiting since birth). Associated symptoms were described with calculation of a novel clinical score. Radiological abnormalities in different age groups were described in relation to the type of vomiting. All patients with bilious vomiting or nonbilious vomiting associated with melena or dysphagia had abnormal findings. Gastroesophageal reflux was detected in 25% of cases. Patients with normal and abnormal study were compared according to their clinical score. The clinical score was significantly higher in the group of patients with abnormal findings (p
