色素内镜技术是指在常规内镜检查的基础上,辅助使用活体染色剂,增加病变与正常组织对比度,增强黏膜表面细小凹凸改变的立体感,使病灶的形态、范围更为清晰,从而提高镜下肉眼识别能力,以便有针对性地取材,提高病变检出率的方法。常用的染料有靛青红(靛胭脂)、美蓝(亚甲蓝,methylene blue,MB)、碘和刚果红等。越来越多的临床研究表明,色素内镜对消化道疾病的诊断有较大价值,但其安
Pigmented endoscopic technology refers to the conventional endoscopic examination, based on the auxiliary use of living stain, to increase the contrast between lesions and normal tissue, and enhance the three-dimensional sense of mucosal surface fine irregularities, the lesion morphology and scope more clearly, thereby enhancing Microscopic identification of the naked eye, in order to be drawn, improve the detection rate of the disease. Common dyes are indigo red (indigo rouge), methylene blue (methylene blue, MB), iodine and Congo red and so on. More and more clinical studies have shown that the pigment endoscopy for the diagnosis of digestive diseases have great value, but its security
