PINERO, Ramón et al. Intestinal metaplasia in esophagus: diagnosis With magnifying endoscopy and flexible Spectral imaging colour enhancement (fice) Corroborated by histology. Gen [online]. 2012, vol.66, n.2, pp.88-92. ISSN 0016-3503.

Standard endoscopy does not identify Barrett's esophagus or mucosa patterns suggestive of intestinal metaplasia. Endoscopic magnification, vital and or virtual chromoscopy reduces this limitation. Aim: Identify intestinal metaplasia with endoscopic magnification and Flexible Spectral Imaging Colour Enhancement (FICE) corroborating it with histology. Patients: Individuals scheduled to undergo routine upper gastrointestinal endoscopy were enrolled. Materials and methods: Upper gastrointestinal endoscopy was performed with Fujinon Inc. 590 EG ZW and EPX 4400 processor. Endoscopy was consecutively performed with: a) high resolution, b) FICE, c) high resolution, d) magnification, e) FICE, f) high resolution. Each found pattern was recorded, was photographed and was saved in JPEG in program Power Point. Biopsy was obtained of the predominant pattern and the pathologist assessed without patient information. Results: 30 patients were included, 11 men and 19 women with 20-83 years and 51.73 years average age range. Patterns of mucosa were observed only with magnification and virtual chromoscopy, Barrett's esophagus was diagnosed in 33.33% of type 3 and none in type 1 and 2. Conclusion: The endoscopic magnification and virtual chromoscopy with FICE identifies intestinal metaplasia and let diagnose Barrett's esophagus.
