PINERO, Ramón et al. Duodenal villi: High resolution endoscopy, magnification, Flexible Spectral Imaging Colour Enhancement (FICE) and histological correlation. Gen [online]. 2012, vol.66, n.4, pp.260-265. ISSN 0016-3503.

Introduction: Standard endoscopy has limits to visualize the duodenal mucosa. With high resolution, magnification with or without chromoscopy it is possible to identify the duodenal villi and its alterations. Objective: Identify duodenal villi and its alterations with endoscopy of high resolution, magnification 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 and EPX 4400 processor, consecutively we practiced: a) high-resolution, b) FICE, c) high resolution d) magnification, e) FICE and f) high resolution. Two samples were taken in bulb and second duodenal portion evaluated by pathologists without patient information. The procedure was recorded, was photographed and was saved in JPEG in program Power Point. Results: 33 patients were included and 66 areas were evaluated in 11 men and 22 women with 20-85 years and 52.66 years average age range. The Z1 pattern of normal duodenal villi agreed in all cases with histopathology. Conclusion: Endoscopic magnification identifies patterns of the duodenal villi and Flexible Spectral Imaging Colour Enhancement (FICE) highlighted them. We found high histological correlation.
