Long-term Helicobacter pylori infection causes premalignant gastric conditions, such as atrophic gastritis and intestinal metaplasia. Image-enhanced endoscopy techniques such as narrow-band imaging (NBI) and magnifying endoscopy improve the diagnosis of gastric intestinal metaplasia (GIM). However, there are no comparative data on the utility of NBI and magnifying endoscopy for diagnosing GIM.
This study aims to evaluate the diagnostic performance of NBI and magnifying endoscopy for GIM in a country with high risk of gastric premalignant lesions.
