DEVELOPMENT OF SPORADIC GASTRIC FUNDIC GLAND POLYP AFTER ERADICATION OF HELICOBACTER PYLORI

The pathogenesis of sporadic gastric fundic gland polyps (FGP) without familial adenomatous polyposis remains unclear. However, development of FGP is associated with normal gastric mucosa without Helicobacter pylori infection. We report two cases of FGP newly developed after successful eradication therapy of H. pylori infection. H. pylori‐associated gastric ulcers occurred in the two patients; H. pylori eradication was performed in the patients and was successful. The patients have not received medication of long‐term proton pump inhibitors. Follow‐up gastrointestinal endoscopy demonstrated a FGP in the fundus of the stomach of each patient after eradication therapy. Regression of sporadic FGP can be observed to coincide with the acquisition of H. pylori infection. Conversely, the present cases demonstrated that the curing of H. pylori infection could lead to the development of FGP.
