Low Prevalence of Extraesophageal Gastrointestinal Pathology in Patients with Eosinophilic Esophagitis.

The yield of gastric and duodenal biopsies in adults with EoE is low, with 6.5% of patients demonstrating histologic features of celiac disease, Helicobacter pylori, EG, and/or EoD. Biopsies of extraesophageal, gastrointestinal sites in patients with suspected or previously diagnosed EoE should consider symptom and endoscopy manifestations as well as the potential impact of histopathologic findings on clinical management.
