Esophagogastric junction outflow obstruction in the differential diagnosis of post-fundoplication dysphagia in children.

Introduction And Aims: Post-fundoplication dysphagia is resolved with no therapeutic intervention in the majority of cases but it can persist in 5.3% of children that undergo the procedure. Among the differential diagnoses, esophagogastric junction outflow obstruction (EGJOO) is a disorder that should be suspected if there is a persistence of dysphagia.
