 Atrophic gastritis and IM(intestinal metaplasia)are well known as precancerous lesions of gastric cancer. The present study evaluated the gastric mucosa for 10years after H. pylori eradication. Patients with successful eradication underwent follow-up endoscopic examination every year prospectively. Biopsy specimens were taken from five points of the stomach as recommended by the updated Sydney system. The courses of 30patients were able to be observed every year for 10years after successful eradication. Atrophy score at all five points were significantly reduced half a year to 6years after eradication. IM score of the lesser curvature of the corpus continued decreasing gradually and showed a significant decrease 6years after. Within 10years after H. pylori eradication, atrophy at all sites and IM in the lesser curvature of the corpus gradually and significantly decreased. These results suggest that the improvement of gastric atrophy and IM might have some kind of association with the reduction of gastric cancer occurrence.
