Eosinophilic oesophagitis (EoE) is a disease identified just over 30 years ago. The main symptom is dysphagia. EoE is initially inflammatory and progresses to fibrosis. There are differences in clinical presentation between young children and adults. Diagnosis is by endoscopy and six biopsies at varying positions of the oesophageal lining. Blood tests are of no diagnostic value as the condition is mediated by IgG4 local mucosal pathology. Endoscopic signs are distinct from those of gastro-oesophageal reflux. Histological signs of EoE are >15 eosinophils/high-power field on a background of hyperplastic mucosa. Options of therapy include diet restriction, proton pump inhibitors therapy and topical steroids but there is a dearth of randomised control trials to define the optimum approach. The only licenced therapy for EoE is budesonide orodispersible tablet, a specific formulation for oesophageal topical steroid therapy. EoE is the most common cause of spontaneous perforation in the oesophagus. Stricture formation occurs in up to 10% and may require therapeutic dilatation.
