ABSTRACT
Objective To evaluate the value of i-Scan in the diagnosis of Barrett′s esophagus.Methods 52 patients diagnosed with Barrett′s esophagus by gastroscopies and pathological examinations were observed under the ordinary edoscopy and i-Scan respectively.Besides,the Barrett's esophageal mucosa were classified by Endo with i-scan mode, the target lesions was taken to be biopsied and pathologically examined.Results ( 1 ) In the 52 patients,mucosal lesions were found in 46 cases (88.5%) under i-Scan and 35 cases (67.3%) under ordinary edoscopy respectively,mucosal lesion detection rate in i-Scan was significantly higher than normal white mode( P<0.01).In the 33 patients which found mucosal lesions in the two modes,the definition of lesion margins,morphology of lesion cryptaeand mucosa capillaries revealed by i-Scan were superior to that by white lighted endoscopy ( P<0.05);(2) Under i-scan mode,the detection of specific intestinal metaplasia ( SIM) of typeⅣ,type V in sensitivi-ty,accuracy,specificity were respectively 90.0%,93.5%,94.4%.Conclusion i-Scan is very easy to operate and has a clear lesion of Barrett′s esophagus,which helps to target the lesion at pathological biopsy.
