Core Tip
Core tip: This is the first study to reveal that the screening performance for gastric cancers by a small caliber-endoscope might not be inferior to that of conventional endoscope. Superficially depressed type lesions in the upper lesser curvature region should be carefully observed in gastric cancer screening in order to decrease false-negative gastric cancers.
