Abstract： 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.
