详细描述
Subjects who are included will recieve Hp eradication therapy based on antimicrobial susceptibility test. After the therapy, the subjects will be divided into two groups, the successful group and the failure group. The subjects who fail to eradicate the Hp after initial treatment and rescue treatment will go into the failure group. Otherwhile, they will go to the successful group.And then they wiil be followed up to observe the development of the gastric mucosa pathology. For mild atrophy gastritis, non- intestinal metaplasial gastritis, follow-up is performed every 2-3 years.For severe atrophy gastritis, intestinal metaplasial gastritis, follow-up is performed every 1-2 years. For patients wth high-grade intraepithelial neoplasia, they can be included 3 months after the endoscopic treatment, and the follow up will be performed at 6, 12 months after the treatment and then the follow up will be carried out every 1 year. For non-atrophic gastritis, no follow-up will be performed. All included patients will recieve a follow-up at the endpoint of 5 years. The follow-up includes endoscopy examination and serum test of PG I,PG II and gastrin 17.
