Rare but probably often non-diagnosed. Esophageal chronic disease of allergic origin. Seems more common among boys. The pathophysiology is unknown but appears to involve a combination of immediate allergy (IgE) and delayed allergy to some food (egg, peanut, soya) or airborne allergens (pollen, mites). Children less than 4 years old are more often allergic to a food while older children and adolescents are more often allergic to airborne allergens.

Diagnosis: symptoms of esophageal dysfunction + histological picture of predominantly eosinophilic inflammation.

Symptoms: pain upon swallowing, food refusal, dysphagia (sometimes food blockage), which do not respond to anti-reflux treatment or antacids; growth retardation.

Endoscopy: macroscopically normal in 30 % of cases; sometimes "train rails" picture.

Treatment: removal of the identified allergen, corticosteroid therapy.

Anesthetic implications:

other signs of atopy (dermatitis, asthma, allergic rhinitis); corticosteroid therapy. There no contraindication to the use of propofol.
