Gastric mucosal prolapse: A case of proton-pump inhibitor nonresponsive dyspepsia.

Gastric mucosal prolapse (GMP) is a rare clinical syndrome that in patients with hiatal hernias and gastroesophageal reflux disease (GERD) may present with typical findings of abdominal pain and reflux symptoms but prove resistant to medical therapy. Physicians should therefore be aware and consider GMP as a differential in such patients in order to make an accurate diagnosis and provide timely treatment.
