Gastric emptying and myoelectrical activity testing in children with esophageal atresia: A pilot study.
JPGN reports. 2024 Februrary
OBJECTIVES: Abnormalities of gastric function in children with esophageal atresia (EA) could potentially contribute to gastrointestinal symptoms and reduced quality of life (QOL). Therefore, we aimed to determine the feasibility and clinical usefulness of gastric function testing in children with EA.
METHODS: The validated PedsQL Gastrointestinal Symptoms Questionnaire (PedsQL-GI) was completed to assess gastrointestinal symptoms and symptom-related QOL. Gastric emptying and gastric myoelectrical activity were studied using 13 C-gastric emptying octanoic acid breath test (13 C-GEBT) and surface electrogastrography (EGG). Correlations between 13 C-GEBT and EGG parameters and PedsQL-GI scores were investigated.
RESULTS: Fifteen patients (four males) were included (median age: 6 [3.0-8.5] years). Mean PedsQL-GI scores as reported by the children were comparable to the healthy population. However, parents reported a diminished QOL. Gastric function tests (gastric emptying and/or surface EGG) showed abnormalities in 12 patients (80%). Patients with abnormal slow waves showed abnormal gastric emptying coefficient more often. There was no significant association between 13 C-GEBT nor EGG results and PedsQL-GI scores.
CONCLUSIONS: 13 C-GEBT and EGG can be used to evaluate gastric function in patients with EA. Abnormal gastric function tests were present in 80% of our cohort. However, abnormal gastric function did not significantly correlate with reported gastrointestinal symptom-related QOL.
