摘　　要：Standard endoscopy with biopsy and narrow-band imaging with guided biopsy are techniques for the detection of Helicobacter pylori(H.pylori)-related gastritis and precancerous lesions.In this study,the authors compared standard endoscopy and magnified narrow-band imaging(commonly known as NBI-M)in the diagnosis of H.pylori infections,atrophic gastritis,and intestinal metaplasia.Although the sensitivity of NBI-M is better than standard endoscopy,the diagnostic accuracy did not differ substantially between the diagnostic modalities.Future prospective studies may guide endoscopists in difficult cases regarding which modality is more useful and cost-effective for the diagnosis of H.pylorirelated gastritis and precancerous conditions.
