Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

After obtaining informed consent from the patients, all the medical history and treatment records of the patients who underwent gastroscopy since the onset of the disease, as well as gastric fluid samples, including laboratory and imaging data, were collected and recorded. The medical history and treatment records and gastric fluid samples were analyzed.
