内镜色素染色对上消化道疾病的诊断价值

目的：探讨内镜色素染色对上消化道疾病的诊断价值。方法：对72例有食管、胃、十二指肠疾病患者行胃镜下局部喷洒染剂后,观察着色情况并取材。结果;18例食管疾患复方碘染色不染区取材,病理示食管癌9例、Barrett食管3例、慢性炎症6例。美蓝染色胃疾患36例中29例（80．55％）着色区取材,胃癌5例、肠化及不典型增生21例、十二指肠球溃疡球部染色18例中11例（61．11％）不染区检出胃上皮化生。结论：内镜色素染色具有扩增内镜诊断的能力,方法简单安全,值得临床推广。

DIAGNOSTIC VALUES ON THE UPPER DIGESTIVETRACT STAININGED BY THE ENDOSCOPY

Discuss the diagnosis values on the upper digestive tract staininged by the endoscopy.Methods:After spraying straining on the 72 cases below parts using stomach endoscopy,who are suffering from esophagus,stomach disease,and duodenal,observe the staining struction and take some samples.Results:Take samples from Lugol's iodine unstaininged but areas on the 18 esophagus disease,the pathobology shows that 9 suffering f from esophagus carcinomas,3 Barrett's esophagus,6 chroinc esophgitis.Taking the staining areas as samples from 29 diseases (it is 80.55% among 36 disease suffering from methylene blue staining stomach),it appears that 5 are suffering from stomach cancer,21 are intestinal metaplosia and gastric dysplasia.Among 18 staining on bulbs of duodenal ulcer,11 unstaininged are checked gastric metaplasia (61.11%).Conclusions:The endoscopy staining possesses the ability of enlarging the endoscopy diagnosis.The method is simple and safe,it is worthy of clinical application and extending.
