Narrow-band imaging Dual focus endoscopy capabilities in diff erential diagnosis of intestinal metaplasia types

Stomach cancer has an important place in medicine. Unfortunately, diagnosis of gastric is being established majority cases at the IV stage. So, yt necessary to detect tumors earliest stages carcinogenesis and evaluate treat precancerous diseases, such as atrophy intestinal metaplasia. Aims : To estimate value Narrow-band imaging Dual focus (NBI Focus) endoscopy capabilities differential metaplasia types. We evaluated data Russian foreign articles on this topic from 2011 2021. In our study 46 patients with suspected admitted Nizhny Novgorod Oncology Dispensary. have performed multimodal endoscopy, including White light (WLI), narrow-band (NBI, WLI, BLI — 28) (18). Sydney system based multifocal biopsy targeted IM foci were all cases. Results Verification metaplasia, visualized was confirmed only 59% However, observed NBI, by pathology 100% NBI Focus made possible differentiate complete incomplete also patients. Conclusions Intestinal can be successfully diagnosed endoscopy. Differential types other variants mucosa using narrow-spectrum dual Focus).
