Parts of patients are diagnosed as H. pylori -negative before ER, whereas the specimens become H. pylori-positive after ER, which may have a role in the recurrence of EGC. Our study aims to determine the difference in H. pylori infection rate of EGC patients before and after ER , and discuss the causes leading to the difference, which can provide references for improving the diagnostic accuracy of H. pylori infection and reducing EGC's recurrence rate.

difference in H. pylori infection rate before and after ER
Information on the H pylori infection status before ER will be collected from the medical records of each patient. A positive result on at least one rapid urease test, urease breath test or Giemsa staining is deemed to be indicative of H pylori infection .Each specimen after ER will be detected H pylori infection status in two weeks. Then we analyze the difference in H. pylori infection rate before and after ER.
in two weeks after endoscopic resection
patients with early gastric lesions
All the lesions will be removed endoscopically or surgically and examine histologically by an independent gastrointestinal pathologist. Each biospecimen after ER will be detected H pylori infection status.
