 Diagnostic potency of endoscopic examination for gastric cancer depends on following factors: 1) experience and detecting ability of an operator, 2) habits of practice in good condition, 3) examination with a fixed observation order, 4) observation techniques such as using distant and near view points, changing directions of observation, changing of pneumatic expansion and etc., 5) selection of an appropriate instrument, 6) techniques of biopsy and interpretation of the biopsy specimen.

 To improve these factors, we emphasize the following requisites in each factor: 1) appraisal of many cases at case conference, 2) discussion on weak points of an operator at case conference, 3) establishment of routine examination protocols, 5) understanding of advantage and disadvantage of a forward-viewing endoscope, 6) front view of lesions at an appropriate distance is a key to make a better biopsy, and biopsy diagnosis should be made with both pathological and endoscopic findings.
