In brief
Retrospective study of 22 pediatric patients demonstrates that timed barium esophagram is a feasible noninvasive screening tool for esophageal emptying disorders in children. Modified diagnostic criteria (1.6 cm barium height at 5 minutes) achieved 100% sensitivity and 80% specificity compared to high-resolution manometry, suggesting pediatric-specific cutoffs may improve diagnostic accuracy over standard adult criteria.

Objectives: Timed barium esophagram (TBE) is a fluoroscopic study that is widely employed as an adjunctive tool for diagnosing esophageal emptying disorders in adults (eg, achalasia, esophagogastric junction outflow obstruction [EGJOO]) and for following response to treatment. We aimed to describe the characteristics and feasibility of a pediatric TBE protocol and provide a first report of the potential value of TBE for assessment of esophageal emptying in the pediatric population.
Methods: Retrospective chart review of pediatric patients at a tertiary pediatric hospital who underwent TBE from October 2017 to October 2019. Patient and test characteristics were summarized using descriptive statistics. Results from patients who had both TBE and high-resolution esophageal manometry (HRM) were used to generate ROC curves for TBE to identify esophageal emptying disorders.
Results: Twenty-two patients underwent 25 TBE. Fourteen of 23 (61%) received 150 mL barium volume per protocol. Nearly half (42%) of subjects could tolerate ingesting barium within 20 seconds. Nine individuals underwent HRM. The sensitivity of standard adult TBE criteria (1 cm barium column height at 5 minutes) to detect emptying disorder was 100%, specificity 40%. A modified diagnostic cutoff (1.6 cm height at 5 minutes) offered 100% sensitivity, 80% specificity.
Conclusions: TBE is feasible and should be considered an adjunctive noninvasive screen for impaired esophageal emptying in children. There was heterogeneous adherence to protocol for timing and volume of barium; however, studies remained interpretable. This population may benefit from different diagnostic cutoffs than adults, and clinical judgment should be used until specific diagnostic cutoffs are determined in children.
