Summary
Brief summary (as posted)
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.

- measure
- difference in H. pylori infection rate before and after ER
- timeFrame
- in two weeks after endoscopic resection
- description
- 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.
