“…Three of 6 of those with a short segment of intestinal metaplasia of the lower esophagus were later diagnosed with BE at follow-up endoscopic evaluation [ 31 ]. Similarly, another study found that 7 of 20 children with intestinal meta-plasia of the esophagus had only columnar metaplasia with no goblet cells at prior evaluation; the authors suggested that gastric metaplasia of the esophagus may be a precursor to BE in some children [ 32 ].…”

Case series Patient: Female, 8-year-old • Male, 15-year-old • Male, 8-year-old • Male, 17-year-old • Male, 11-year-old Final Diagnosis: Columnar metaplasia of the esophagus Symptoms: Iron deficiency anemia Medication: — Clinical Procedure: Esophagogastroduodenoscooy Specialty: Gastroenterology and Hepatology Objective: Rare coexistence of disease or pathology Background: Columnar metaplasia of the lower esophagus includes both gastric and intestinal metaplasia. Children with severe neurologic impairment and congenital esophageal atresia often have gastroesophageal reflux disease, which can lead to Barrett’s esophagus, a form of lower esophageal columnar metaplasia and precursor to esophageal adenocarcinoma, with some, but not all, guidelines specifically requiring the presence of intestinal metaplasia for diagnosis. This case series illustrates how iron deficiency anemia may be the primary symptom of esophageal columnar metaplasia in such children and how upper endoscopy is essential in their initial and ongoing evaluation. Case Reports: We review 5 cases of columnar metaplasia of the lower esophagus in children, 3 with severe neurologic impairment and 2 with esophageal atresia. Each child presented with marked iron deficiency anemia and minimal-to-no gastrointestinal symptoms. Conclusions: We conclude that columnar metaplasia of the esophagus may present with iron deficiency anemia in children with neurologic impairment or congenital esophageal atresia, even if without overt gastrointestinal symptoms. Accordingly, we propose that early endoscopic evaluation should be considered in this specific patient population. Based on our literature review, we also emphasize the need for guidelines on the endoscopic surveil-lance of such children with any type of columnar metaplasia of the lower esophagus, given the associated risk of malignant transformation.
