PINERO, Ramón et al. Diagnosis of Helicobacter pylori infection in gastric body with endoscopic magnification and Flexible Spectral Imaging Colour Enhancement (FICE). Gen [online]. 2013, vol.67, n.2, pp.71-75. ISSN 0016-3503.

Helicobacter pylori infection is not diagnosed with standard endoscopy. With high resolution and magnification patterns of gastric mucosa suggesting its presence are observed. Objective: Diagnose Helicobacter pylori infection with endoscopic 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 ZW and EPX 4400 processor. Endoscopy was practiced on both sides of the gastric body consecutively with: a) high-resolution, b) magnification, c) high-resolution, d) FICE, e) magnification and g) biopsy of the antrum and the pattern more prevalent on each side of the body evaluated without patient information. The entire procedure was recorded, was photographed and was saved in JPEG in program Power Point. Results: 60 Areas in 30 patients were evaluated: 10 men and 20 women with ages of 20-82 years and average 49.60. Only magnification and FICE identified patterns of mucosa in gastric body. Helicobacter pylori was diagnosed in 37.03% with histology and in pattern Z2 and Z3 in 53.33% and 61.11% respectively. Conclusion: The endoscopic magnification and Flexible Spectral Imaging Colour Enhancement (FICE) identify patterns of gastric mucosa suggesting Helicobacter pylori infection.
