In this study, we proposed a prospective study about the effect of the automatic surveillance system on surveillance rate of patients with gastric premalignant lesions. The enrolled patients were divided into group A with intelligent surveillance system, group B with manual reminder, and group C with natural state. The surveillance among the three groups will be compared.
Male or female aged 18 years or older who undergo upper endoscopy.
1)No contact information or invalid contact information.
2) The surveillance interval cannot be determined according to the surveillance guidelines, including no upper gastrointestinal pathology, therapeutic endoscopy or with history of previous gastrectomy, esophagectomy, or ESD, no dysplasia degrees, no biopsy sites, non-epithelial lesions, duodenal lesions, ulcer and so on.
3) Needless for surveillance or others.
4) High-grade intraepithelial neoplasia or cancer of the esophagus or stomach.
