Brief Summary

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

Although endoscopic findings of H. pylori have been reported in the literature, there is still some debate over whether H. pylori-related gastritis can be diagnosed via endoscopic features alone. Most studies concluded that it is not possible to diagnose H. pylori-related gastritis on the basis of endoscopic findings. However, the resolution power of endoscopy has greatly improved in recent years and the exact examination of gastric mucosa was possible.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Our study aimed to achieve the following: (1) describe the H. pylori-related mucosal pattern in the gastric corpus using high-definition endoscopy; (2) evaluate the diagnostic accuracy for H. pylori detection; (3) find the optimal biopsy site for rapid urease test (RUT); (4) validate the inter- and intraobserver agreement in the assessment of endoscopic patterns.
