Core Tip
Core Tip: The prevalence of cardiac and antral nodularity in Helicobacter pylori (H. pylori)-negative, -positive, and -eradicated patients were 0.14% and 0.14%, 54.5% and 29.5%, and 4.5% and 0.6%, respectively. Cardiac nodularity was more frequent than antral nodularity in H. pylori-positive and -eradicated patients. Cardiac nodularity was often found in younger patients and patients with less intestinal metaplasia. Cardiac nodularity decreased after eradication, especially in patients who underwent eradication a long time ago.
