Diagnostic Considerations
Vomiting is a symptom associated with many disorders. Accordingly, gastroesophageal reflux cannot be assumed to be the primary problem in infants and children who present with a history of emesis. Warning signals that herald the requirement for additional evaluation include the following:
-
Bilious or forceful vomiting
-
Hematemesis or hematochezia
-
Vomiting with diarrhea
-
Abdominal tenderness or distention
-
Onset of vomiting after 6 months of life
-
Fever, lethargy, hepatosplenomegaly
-
Macrocephaly, microcephaly, seizures
The occurrence of any of these signs and symptoms indicates the need to consider a comprehensive metabolic, neurologic, and/or surgical evaluation, in addition to a gastroenterologic workup.
Conditions to consider in the differential diagnosis of gastroesophageal reflux include the following:
-
Antral web
-
Intestinal motility disorders, including achalasia, collagen-vascular disorders (e.g. systemic sclerosis)
-
Eosinophilic esophagitis
-
Helicobacter pylori associated gastritis
-
Irritable bowel syndrome
-
Peptic ulcer disease
-
Tracheoesophageal fistula
