Abstract
The patient, a 73-year-old woman, had been taking acid-suppressive therapy for refractory reflux esophagitis for 10 years. A potassium-competitive acid blocker was administered to strengthen acid-suppressive therapy for worsening symptoms of gastroesophageal reflux disease. Esophagogastroduodenoscopy showed an increase in the number and size of fundic gland polyposis (FGPs). When acid-suppressive therapy was changed from potassium-competitive acid blocker to proton pump inhibitor, the FGPs showed reduced size 1 year later. Furthermore, when acid-suppressive therapy was changed from proton pump inhibitor to histamine-2 receptor antagonist, FGPs were even smaller after 1 and 2 years. The patient, who had no flare-up of gastroesophageal reflux disease symptoms, continues to be treated medically with histamine-2 receptor antagonist. This case report describes changes in endoscopic findings of a patient with FGPs caused by acid-suppressive therapy for refractory gastroesophageal reflux disease.
