色素放大内镜下Barrett食管微细结构的分析

目的研究色素放大内镜下Barrett食管（BE）微细结构的变化及与病理组织学的相关性，提高BE镜下诊断。方法应用放大内镜对疑似BE黏膜进行染色放大观察并做病检，记录67例经病理确诊BE病例的临床表现、内镜特点及病理分型。结果BE的内镜分型：岛型28例，舌型7例，全周型32例。放大内镜共分三型，其中Ⅲ型病理均为肠上皮化生，肠化生检出率与Ⅰ型、Ⅱ型比较差异有统计学意义（x^2=21．8，P〈0．01）。结论色素内镜在Barrett食管的诊断和组织学较常规内镜有较好的一致性。

Ultrastructural analysis of Barrett's esophagus under magnifying chromoendoscopy

Objective To study Barrett's esophageal consistency with its histological findings,which were found with magnifying chromoendo6copy,and to advance the endoscopic diagnosis of Barrett's esophagus. Methods The patients with BE were diagnosed by endoscopy and histology, and their histological findings and endoscopic appearances of a total of 67 patients with BE were observed. Results Endoscopic appearances type of BE showed island (28 cases) ,tongue(7 cases) ,and circum ference(32 cases). Three types of BE under magnifying chromoendoscopy,and in magnifying endoscope group,type Ⅲ which were found with magnifying endoscope were verified intestinalisation epithelium pat ho-type, compared with type I and type Ⅱ,the discrepancy of them had statistical significance(P＜0.01). Conclusion Magnifying chromoendoscopy had a relatively better consistency in the diagnosis of Barrett's esophagus with histological findings.
