 Despite developments in endoscopic systems, there are many gastric cancers the margins of which cannot be determined by conventional endoscopy. ME-NBI(magnifying endoscopy with narrow band imaging)is very useful in diagnosing these margins. To improve its precision, we have to attach a soft black hood to the scope tip to obtain high magnification NBI images in focus, and we recommend setting the image enhancement to level B8. To diagnose gastric cancers, we observe microsurface patterns and microvascular patterns by magnifying endoscopy, and the maximal optical magnifying ratio must be used to observe the microvascular patterns in detail. To perform ME-NBI, we should understand not only the structure of gastric cancers but also the basic structure of normal stomach and gastritis.
