Failed Nissen fundoplication in two patients who had persistent vomiting and eosinophilic esophagitis

The following report describes two patients who had chronic symptoms of gastroesophageal reflux and persistent histological esophagitis, despite aggressive medical antireflux therapy, who continued to have esophagitis and remained symptomatic post antireflux surgery (Nissen fundoplication). Both patients demonstrated a severe eosinophilic esophagitis with normal gastric and duodenal histology before and after surgery. Postoperatively, each received the diagnosis of allergic enteritis and both responded clinically and histologically to oral corticosteroids and an elemental diet.
