Eosinophilic gastroenteritis is often difficult to treat owing to recurrent mucosal edema, redness, and especially progression to erosion or ulceration. We describe here the case of a patient with eosinophilic gastroenteritis showing duodenal stenosis of the entire circumference due to mucosal ulcer, which was successfully treated by allergy elimination. A 3-year-old boy was brought to a nearby hospital with the chief complaint of repeated vomiting; he was diagnosed as having duodenal ulcer by endoscopic examination. He had been conservatively treated for a year; however, vomiting persisted owing to retractable duodenal stenosis. He was transferred to our hospital for further treatment of retractable duodenal ulcer disease. Gastric mucosal biopsy via endoscopy showed eosinophil infiltration. The RAST showed a positive result for milk and lactalbumin. He was finally diagnosed as having eosinophilic gastroenteritis. His duodenal ulcer and stenosis were improved by the treatment including dairy or milk product removal from his diet. Allergy elimination is a useful treatment strategy not only for duodenal ulcer, but also duodenal stenosis, as we learned in this case. One should take into consideration the possibility of eosinophilic gastroenteritis in the case of retractable peptic ulcer disease with duodenal scar stenosis, followed by prompt treatment including allergy elimination.
