【摘要】 目的：探讨内镜下碘染色对食管癌和癌前病变的诊断价值。方法：选择2015年6-12月于本院行胃镜活检并存在可疑病灶的184例患者作为研究对象，并对其进行碘染色和病理学检查，分析胃镜下碘染色结果与病理结果之间的关系。结果：184例患者中食管鳞癌42例、不典型增生69例(其中重度12例、中度30例、轻度27例)、慢性食管炎51例以及鳞状上皮增生22例。碘染色后食管癌主要表现为不染，占90.5%(38/42)；癌前病变主要表现为不染和淡染，占97.1%(67/69)；食管癌及重度不典型增生主要表现为不染，占87.0%(47/54)。结论：食管癌癌前病变在碘染色下主要表现为不染和淡染；碘染色对食管癌和食管癌前病变的筛检具有十分重要的临床价值。
