PINERO, Ramón et al. Endoscopic magnification, acetic acid and flexible spectral imaging colour enhancement (fice) for the diagnosis of Barrett´s esophagus. Gen [online]. 2012, vol.66, n.3, pp.151-154. ISSN 0016-3503.

Standard endoscopy does not identify Barrett´s esophagus, but endoscopic magnification and chromoendoscopy diagnose it accurately. Ojective: Diagnose Barrett’s esophagus with magnification endoscopy, spraying of acetic acid and Flexible Spectral Imaging Colour Enhancement (FICE). 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) highresolution, b) FICE, c) high resolution d) magnification, e) FICE, f) high resolution with spraying of 5% acetic acid in distal esophagus inmediately washed with 20cc of water, g) magnification and h) FICE. Biopsy was taken and evaluated without patient information. The procedure was recorded, was photographed and was saved in JPEG in Power Point program. Results: In 120 patients: 44 men and 76 women aged 20-85 years, pit patterns of mucosa were enhanced with acetic acid sprayed in distal esophagus and highlighted with magnification and FICE. Barrett’s esophagus was diagnosed in 87.50% of cases with long columnar tongues and pit pattern type 3. Conclusion: Endoscopic magnification with spraying of acetic acid, and Flexible Spectral Imaging Colour Enhancement (FICE), identified and highlighted the pattern suggestive of diagnosis of Barrett’s esophagus.
