a Prospective Study on the Efficacy of Magnifying Endoscopy With Narrow-band Imaging in Diagnosing Gastric Lesions


Inclusion Criteria:



- patients with gastric lesions which were detected by conventional screening endoscopy
and suspected of early malignancy.

Exclusion Criteria:

- advanced gastric cancer or any other malignancy;

- patients under unsuitable conditions for examination or treatment, such as acute
