目的探讨内镜下碘染色对食管病变的早期诊断价值。方法对26例食管病变可疑患者局部喷洒碘染剂后,观察着色情况并取材活检。结果 26例患者食管黏膜碘染色后有不着色区或明显淡染区,病理显示单纯增生和炎症10例,不典型增生9例,Barrett食管2例,食管癌5例。结论内镜下碘染色可提高食管病变,尤其是食管癌的早期诊断率,方法简单,值得临床推广应用。
Objective To investigate the value of endoscopic iodine staining in the early diagnosis of esophageal lesions. Methods Twenty-six cases of suspected esophageal lesions were stained with iodine dye and observed biopsies. Results Twenty-six patients had non-coloring area or obvious light-stained area after iodine staining of esophageal mucosa. The pathology showed simple hyperplasia and inflammation in 10 cases, atypical hyperplasia in 9 cases, Barrett’s esophagus in 2 cases and esophageal carcinoma in 5 cases. Conclusion Endoscopic iodine staining can improve esophageal lesions, especially the early diagnosis of esophageal cancer, the method is simple and worthy of clinical application.
