ABSTRACT
ObjectiveTo evaluate digital chrome endoscopy (I-Scan) and confocal laser endomicroscopy (CLE) for diagnosis of Barrett esophagus (BE).MethodsFrom July 2010 to July 2011,a total of 878 outpatients who had upper gastrointestinal symptoms underwent routine endoscopy and I-Scan examination,screened patients with suspected Barrett's epithelial were further referred to CLE and endoscopy.The detection rate and image features of BE between routine endoscopy and I-Scan,and the diagnosis of BE between pathology and CLE,were compared respectively.ResultsSuspected BE was diagnosed in 46 patients (5.2%) by routine endoscopy,and in52 (5.9%) by I-Scan,and there was no significant difference in detection rate between 2 methods (x2 =0.533,P > 0.05 ).The detection rate of paliform blood vessels between SCJ and GEJ was higher using I-Scan (35/52,67.3% ) than routine endoscope (21/46,45.7%,P <0.05).A total of 19 suspected BE underwent CLE and biopsy,and BE was diagnosed by CLE with a sensitivity of 93% and a specificity of 100%.ConclusionI-Scan is capable of identifying paliform blood vessels between SCJ and GEJ,and can improve the detection rate of suspected BE.CLE is able to provide in-vivo histological diagnosis of BE with a high sensitivity and specificity.
