Brief Summary:

Magnifying endoscopy with narrow-band imaging (ME-NBI) can emphasize surface pattern and microvascular architecture of the gastric mucosa.However,the usefulness and criteria of NBI for differential diagnosis among early gastric cancers (EGC) have not been fully established.The study is based on the hypothesis:

  1. ME-NBI is useful in distinguishing EGC from other gastric lesions
  2. ME-NBI is useful in further differential diagnosis among EGCs.

Primary Outcome Measures :
  1. diagnosis accuracy of ME-NBI [ Time Frame: in 2 weeks after ME-NBI examination ]
    ME-NBI diagnosis was made during real-time endoscopy procedure and reviewed in two weeks after ME-NBI examination. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of ME-NBI diagnosis compared with histology were measured.

Biospecimen Retention:   Samples Without DNA
Samples after biopsy or resection are to be retained.
