The relation between Helicobacter pylori infection and gastric cancer has been proven in epidemiological studies and animal experiments. Our aim was to investigate the prophylactic effect of H pylori eradication on the development of metachronous gastric carcinoma after endoscopic resection for early gastric cancer.
