We describe the basic principles and clinical usefulness of modern magnifying endoscopy techniques, using white-light imaging or narrow-band imaging, for precise diagnosis of small flat gastric cancers. Regarding technology, first, the resolution provided by the endoscope is important in order to consistently visualize the precise morphology of microvascular architecture, and second, the use of a distal attachment (soft hood or cap) is essential in order to maintain a constant distance between the tip of the scope and the mucosal surface. Regarding methodology, a systematic but simple classification system based on microvascular pattern and microsurface pattern (the "VS classification") is proposed. The technique based on the principles described here can be applied not only in routine endoscopic examination but also in the detailed preoperative assessment of the lateral extent of early gastric cancer, before endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD).
我们描述了现代放大内镜技术（使用白光成像或窄带成像）在精确诊断小的扁平型胃癌方面的基本原理和临床实用性。关于技术，首先，内镜提供的分辨率对于持续清晰显示微血管结构的精确形态很重要，其次，使用远端附件（软帽或透明帽）对于保持内镜尖端与黏膜表面之间的恒定距离至关重要。关于方法，提出了一种基于微血管形态和微表面形态的系统但简单的分类系统（“VS 分类”）。基于此处所述原理的技术不仅可应用于常规内镜检查，还可应用于内镜黏膜切除术（EMR）或内镜黏膜下剥离术（ESD）前早期胃癌侧向范围的详细术前评估。
