Out of 156 cases of patients treated for Helicobacter pylori (H. pylori),there were 12 examples of gastric erosions (7.7％) and 14 examples of duodenal erosions (9％).
As clinical features, the duodenal erosions were mainly recognized 1～3 months after H. pylori eradication. On the other hand, the gastric erosions were mainly recognized 1 year after H. pylori eradication. Both types of erosions were mainly recognized from mild atrophy of the gastric mucosa in spite of successful H. pylori eradication. These were transient lesions which disappeared after follow-up in most case. There were also many subclinical cases, but only a few of them required the administration of acid suppressives.
As endoscopic features,the gastric erosions were mainly recognized as erosions consisting of multiple small spots and hemorrhagic erosions. On the other hand,the duodenal erosions were mainly recognized as a comparatively large map-like state produced by banded erosions.
