Introduction: Endoscopic diagnosis of Barrett's esophagus is given by the finding of tabs or patches of mucus in tubular esophagus but taking the biopsy may have sampling errors. Magnification endoscopy and electronic chromoscopy as Flexible Spectral Imaging Color Enhancement (FICE) represent the application of endoscopy technique with a high diagnostic capability of Barrett's Esophagus. Objective: To study the diagnostic capacity of electronic Chromoscopy using FICE system in Barrett's esophagus. Materials and Methods: A prospective cross-sectional study with a non-probabilistic intentional sampling, from May 2007 to February 2016. 206 patients were included. The classification of the findings of the mucosal patterns (Pit) was performed by the Classification of Barrett’s epithelium by magnifying endoscopy of Takao Endo and underwent histology and immunohistochemistry. Results: pit 1: 120 (100%), pit 2: 36 (97 %%), pit 3: 21 (84%), pit 4: 17 (100%), pit 5: 7 (100%). These results confirm the ability of endoscopy diagnosed when classification Takao Endo is used, with the same for endoscopy and histology Immunohistochemistry stockings. Conclusion: Endoscopy magnification and Chromoscopy Electronics FICE has a high diagnostic capability of Barrett's Esophagus.
