Now that minimally invasive treatment is performed more widely, it is important that more cases indicated for such treatment are diagnosed, i.e., microcancers that can be treated endoscopically should be accurately diagnosed. Since the diameter of early gastric cancer indicated for endoscopic treatment is generally less than 2.0 cm, detection of these microcancers is crucial and improvement in the endoscopic diagnosis is needed. We discuss the method for measuring lesion size, the procedure of dye scattering endoscopy, and the types of dyes used in this examination. In addition, we describe a method for increasing the diagnostic accuracy in the color of the vasoconstriction by the spraying of a drug that acts directly on the capillaries in the gastric mucosa. These basic aspects of endoscopic diagnosis of early gastric cancer will significantly assist gastroenterologists. We hope that these skills will be mastered and that endoscopic diagnosis, built on a firm foundation, will become even more widespread.
鉴于微创治疗的应用越来越广泛，准确诊断更多适合此类治疗的病例非常重要，即能够通过内镜治疗的微小癌应被准确诊断。由于适合内镜治疗的早期胃癌直径一般小于2.0厘米，检测这些微小癌至关重要，且需要提高内镜诊断水平。我们讨论了病变大小的测量方法、染料散射内镜检查的操作步骤以及该检查中使用的染料类型。此外，我们还描述了一种通过喷洒直接作用于胃黏膜毛细血管的药物来提高血管收缩颜色诊断准确性的方法。早期胃癌内镜诊断的这些基本方面将极大地帮助胃肠病学家。我们希望这些技术能够得到掌握，并且基于坚实基础的内镜诊断将得到更广泛的应用。
