放大内镜对早期消化系肿瘤及其癌前病变的诊断价值

Diagnostic value of magnifying endoscopy in early-stage gastrointestinal tumors and their precancerous lesions

随着内镜技术的发展和在临床诊断中的作用日益收到重视,放大内镜在临床中也逐渐受到青睐,并越来越多运用于临床.目前新型的放大内镜可清晰显示消化道黏膜腺管开口和微细血管等细微结构的变化,发现和诊断普通内镜难以发现的一些早期病变,特别是早期恶性肿瘤及其癌前病变.近年来在放大内镜检查中更配于染色对比及窄带成像等技术,使放大内镜的的运用得到进一步拓展.本文就放大内镜对早期消化系肿瘤及其癌前病变的诊断价值作一综述.

With advance in endoscopic technology and its increasing importance in clinical diagnosis, magnifying endoscopy has attracted increasing attention and has been widely used in clinics. At present the new magnifying endoscope is able to clearly demonstrate duct openings of gastrointes-tinal tract mucosa and microstructural changes, thus enabling discovery and diagnosis of early lesions that are difficult for common endoscope, especially early-stage malignant tumors and pre-cancerous lesions. Recently, magnifying endosco-py in combination with staining or with narrow-band imaging technology facilitates its wider use. This paper reviewed the diagnostic value of mag-nifying endoscopy in early-stage gastrointestinal tumors and precancerous lesions.
