Further longitudinal studies are needed to confirm our findings.

Method In phase I, 64 patients with gastric mucosal lesions diagnosed by gastrointestinal endoscopy were enrolled in the study. Normal mucosa and suspicious lesions were evaluated under normal white light imaging (WLI) and pCLE mode. Descriptive characteristic of gastric mucosal inflammation and atrophy under pCLE were defined according to the histology. In phase II, the criteria for nonatrophic gastritis (NAG) and chronic atrophic gastritis (CAG) under pCLE were used to diagnose the mucosal lesions in 431 patients. Diagnostic accuracy of each endoscopy modes was evaluated by measuring the concordance with histology. Result A total of 64 patients with 187 positions were enrolled in the first part of this study. According to the histological diagnosis, the vessel diameter was increased in the NAG (11.18 ± 0.1 μm) and CAG (13.21 ± 0.29 μm) and CAG (13.21 ± 0.29 μm) and CAG (13.21 ± 0.29 μm) and CAG (13.21 ± 0.29 μm) and CAG (13.21 ± 0.29 μm) and CAG (13.21 ± 0.29 μm) and CAG (13.21 ± 0.29 . Conclusion pCLE shows high potential for the diagnosis of gastric inflammation and atrophy based on quantitative criteria and has the ability to be a substitute for histology in the diagnosis of diffuse lesions in the stomach.
