放大内镜(ME)是一种具有高像素和高分辨率特点的电子内镜,可将内镜下的图像放大数十倍到上百倍,窄带成像技术(NBI)利用滤光器使内镜光源中仅留下窄带光谱,增强了消化道黏膜血管的图像。NBI联合放大内镜(NBI-ME)就能清晰的观察胃黏膜腺管开口以及微血管形态,从而可以达到鉴别病变良恶性的目的 ,在胃黏膜早期病变的诊断中发挥了巨大作用。1幽门螺杆菌(Hp)相关性胃炎目前研究证实,Hp感染与胃黏膜疾病的发生密切相关。
Magnifying endoscopy (ME) is an electronic endoscope with high pixel and high resolution that magnifies the endoscopic image tens to hundreds of times. Narrow band imaging (NBI) utilizes filters to move the endoscope Only narrowband light is left in the light source, enhancing the image of the mucosal blood vessels in the digestive tract. NBI combined magnifying endoscopy (NBI-ME) will be able to clearly observe the gastric mucosal gland opening and microvascular morphology, which can achieve the purpose of identifying benign and malignant lesions, in the early diagnosis of gastric mucosal lesions played a significant role. 1 Helicobacter pylori (Hp) -related gastritis studies have confirmed that Hp infection and gastric mucosal diseases are closely related.
