DOZ047.57: Eosinophilic esophagitis in an infant with repaired esophageal atresia and tracheoesophageal fistula
Abstract Esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) requires early surgical intervention in life, following which symptoms related to esophageal dysmotility, gastroesophageal reflux, and strictures may develop. Eosinophilic esophagitis (EoE) is an immune-mediated disorder presents with vomiting and dysphagia. The appearance of exudates, rings, and furrows during endoscopy and the presence of >15 eosinophils/HPF in biopsy confirm the diagnosis. Treatment options include elimination diet, proton pump inhibitors (PPI), and topical steroids. We report a full-term male who had EA and TEF repaired in the second day of life. At 11 months of age, he developed progressive vomiting, contrast study showed esophageal dysmotility with slow emptying and no stricture. The initial endoscopy showed a mild nonobstructive narrowing 5 cm above the gastroesophageal junction, below which the mucosa was erythematous, biopsies showed >25 eosinophils/HPF. Started treatment with PPI and endoscopy repeated three months later showed same endoscopic features and biopsies showed >45 eosinophils/HPF. Allergy testing was positive for milk, wheat, oat, and rice. Topical steroids and elimination diet were added to PPI. At 32 months of age, the child was asymptomatic, not on elimination diet and treatment was stopped. Repeat endoscopy showed longitudinal furrows and erosions of the lower esophagus, no stricture, and biopsies showed >15 eosinophils/HPF. Steroids, PPI, and elimination diet were all resumed. Despite moderate esophagitis due to EoE and poor compliance to treatment, our patient shows normal growth, development, and symptoms resolution. Asymptomatic children with repaired EA and treated EoE may require close follow-up and repeat endoscopy.
