How often would you perform an upper endoscopy on an individual with chronic gastritis and previously eradicated H pylori with respect to risk of gastric malignancy?

Endoscopic surveillance of patients with chronic gastritis and previously eradicated Helicobacter pylori (H. pylori) would primarily hinge on endoscopic/histologic features on index endoscopy.

Endoscopically and histologically, the presence and extent/distribution of gastric pre-neoplastic lesions noted on index upper endoscopy would help determine the need for future endoscopic surveillance. Chronic gastritis in itself would not warrant endoscopic surveillance, but the presence of gastric atroph...
