title: [Endoscopic diagnosis of erosive and ulcerative lesions in the stomach and duodenum using NBI technology].
abstract: The study was designed to assess the value of a new NBI-based digital videoendoscopic system for the diagnosis of erosive and ulcerative lesions in the stomach and duodenum of 136 patients in comparison with 185 ones examined with the use of conventional fiber-optic and videoendoscopes. Patients of group 1 were examined using a GIF-H180 EVIS Exera-I apparatus ("Olympus", Japan), controls with GIF-Q40 and GIF-Q160 EVIS Exera-II endoscopes ("Olympus", Japan). Endoscopic signs of inflammation, its extent and severity were recorded. NBI endoscopy revealed perifocal inflammatory changes associated with ulcerative lesions in the stomach and duodenum as spots of different tones of blue. This method allowed for the detection of lesions not visualized by conventional techniques. The use of NBI technology for routine endogastroduodenoscopy in patients with erosive and ulcerative lesions in the stomach and duodenum improves visualization of even minor changes in gastric and duodenal mucosa (p < 0.05).
