A diagnostic delay of 10 years in the DanEoE cohort calls for focus on education - a population-based cross-sectional study of incidence, diagnostic process and complications of eosinophilic oesophagitis in the North Denmark Region.

The EoE incidence was documented. The diagnostic process was analyzed and showed an unmet need for education among referring physicians and endoscopists: A diagnostic delay of a decade, infrequently noted macroscopic EoE changes and lack of treatment at the debut in one fifth. Strictures in the DanEoE cohort were rare whereas food bolus obstruction was frequent.
