Abstract

This paper provides an overview of the principles of a vessel plus surface (VS) classification system to explain the diagnostic system of early gastric cancer using image-enhanced magnifying endoscopy. Furthermore, this paper introduces the magnifying endoscopy simple diagnostic algorithm for gastric cancer (MEADA-G) developed according to the VS classification system, with a description of the procedures performed for diagnosis. In addition to the diagnostic system, white opaque substance (WOS), light blue crest (LBC), white globe appearance (WGA), and vessels within epithelial circle (VEC) patterns, which are representative findings that can be observed in the gastric mucosa by image-enhanced magnifying endoscopy, are also described. Image-enhanced magnifying endoscopy is particularly useful in the diagnosis of differentiated-type early gastric cancer. It is important to use the appropriate clinical strategies based on a comprehensive understanding of the usefulness and limitations of the diagnostic system described in this paper.

影像增强内镜诊断早期胃癌的系统方法。

本文概述了血管+表面(VS)分类系统的原理，以解释图像增强放大内镜对早期胃癌的诊断系统。此外，本文还介绍了根据VS分类系统开发的胃癌放大内镜简易诊断算法(MEADA-G)，并对诊断过程进行了描述。除了诊断系统外，还描述了白色不透明物质(WOS)，浅蓝色波峰(LBC)，白色球形外观(WGA)和上皮圈内血管(VEC)模式，这些都是图像增强放大内镜在胃粘膜中观察到的代表性发现。图像增强放大内镜在鉴别型早期胃癌的诊断中特别有用。重要的是要使用适当的临床策略，基于对有用性和局限性的诊断系统的全面理解在本文中描述。

期刊介绍： Translational Gastroenterology and Hepatology (Transl Gastroenterol Hepatol; TGH; Online ISSN 2415-1289) is an open-access, peer-reviewed online journal that focuses on cutting-edge findings in the field of translational research in gastroenterology and hepatology and provides current and practical information on diagnosis, prevention and clinical investigations of gastrointestinal, pancreas, gallbladder and hepatic diseases. Specific areas of interest include, but not limited to, multimodality therapy, biomarkers, imaging, biology, pathology, and technical advances related to gastrointestinal and hepatic diseases. Contributions pertinent to gastroenterology and hepatology are also included from related fields such as nutrition, surgery, public health, human genetics, basic sciences, education, sociology, and nursing.
