Core Tip

Core tip: This is a retrospective study to evaluate the effect of Helicobacter pylori (H. pylori) status test and H. pylori eradication on the occurrence of metachronous gastric cancer (MGC) after endoscopic submucosal dissection (ESD) of early gastric cancer (EGC) and risk factors of MGC. H. pylori status test and H. pylori eradication seems to have no preventive effect on the occurrence of MGC after ESD for EGC. The risk factors of MGC were endoscopic gastric mucosal atrophy in H. pylori tested group alone and intestinal metaplasia in all patients.
