Assessment of the Efficiency of the Narrow-Band Imaging With Optical Magnification in the Diagnostics of Upper Gastrointestinal Diseases

The article is devoted to the study of the capabilities of the EG-2990Zi video gastroscope combined with the EPK-i7000 Pentax video processor in the process of comparative assessment of the effectiveness of using narrow-band video imaging with optical magnification in diagnosing certain diseases of upper gastrointestinal, namely, the esophagus, gaster, and duodenum. In particular, the method of comparative assessment of the mucous coat condition and morphological criteria in patients with Barrett's esophagus, as one of the serious complications of gastroesophageal reflux disease, is considered when performing narrow-band video imaging with optical magnification compared to a routine endoscopic examination technique. At the second stage, endoscopic indices and morphological diagnostic criteria in patients with ulcers and cicatricial deformity of the gaster and duodenum were compared. The final stage is connected with the study of the state of the mucous coat and morphological criteria in patients with polyps of the stomach and duodenum. The result of a comparative analysis of the findings obtained using these methods enables the early detection of changes in the mucous coat of the esophagus, preceding neoplastic ones when coinciding with the morphological conclusion in patients with the above diseases. The main points of scientific novelty include the following: a clear diagnostic algorithm has been first proposed for diseases of upper gastrointestinal diseases, taking into account the use of innovative technologies combined with a morphological study of biopsy material, which differs from routine endoscopic examination only in white light using a logical structure of study of the effectiveness of various endoscopic imaging visualization modes in terms of detailing of the micrograph and angioarchitecture of the mucous coat during the identification of spread and extent of manifestation of various chronic pathologies of the esophagus, gaster and duodenum; it has been proposed to assess the inter-relation between the data of endoscopic examinations and morphological criteria within the independent main and control groups, differing in the use of correlation analysis by the Spearman criterion and allowing to statistically substantiate the advantages of narrow-band imaging with hig

Primary esophageal Paget’s disease is rare. Only a few case reports have described the intraepithelial papillary capillary loop (IPCL) pattern obtained by magnified Narrow Band Imaging (M-NBI) endoscopy in this rare pathology. This report highlights the usefulness of M-NBI and the successful diagnosis using a large bloc specimen obtained by endoscopic mucosal resection with the cap method (EMR−c). A 53-year-old man was referred to endoscopic examination for dysphagia. The endoscopic image revealed a ring-shaped scarring of the esophagus suggestive for eosinophilic esophagitis. The IPCL pattern by M-NBI endoscopy showed an inflammatory pattern, and the entire epithelium of the esophagus was not stained by Lugol iodine spraying. Based on six biopsies randomly performed, a poorly differentiated adenocarcinoma was diagnosed. Since the M-NBI pattern and the histology were completely different, EMR−c was performed to obtain large bloc specimens for a more detailed diagnosis. The pathological findings revealed extensive Paget’s cells infiltration into the epithelium and multifocal invasion from the mucosa to the submucosal layer with adenocarcinoma. In conclusion, a large bloc specimen by EMR-c might be more useful than a small biopsy for an accurate diagnosis of the rare esophageal Paget’s disease.Key words: – – .Abbreviations: EMR−c: endoscopic mucosal resection with cap method; IPCL: intraepithelial papillary capillary loop; LVLs: Lugol-voiding lesions; M-NBI: magnified Narrow Band Imaging; PET-CT: Positron-Emission Tomography and Computed Tomography.

Gastric Hyperplastic Polyp

A case of gastric hyperplastic polyp with proliferation of xanthoma cells is reported. The patient was a 69-year-old man who visited our hospital for further evaluation of gastric polyps. Endoscopic examination of the upper digestive tract revealed multiple hyperplastic polyps in the gastric antrum. There was a pedunculated polyp with whitish yellow granules, 7 mm in diameter, arising from the greater curvature of the antrum. Magnification narrow-band imaging endoscopy (GIF-H260Z, Olympus) revealed long microcapillaries in the polyp but did not reveal disappearance of the mucosal microstructure or irregular branched capillaries. Endoscopic mucosal resection (EMR) was performed. Histological examination of the specimen revealed the lengthened gastric foveolae in the superficial portion and tight sheet of foamy histiocytes in the lamina propria. Diagnosis of gastric hyperplastic polyp with proliferation of xanthoma cells was made. There was no evidence of malignancy. It is necessary to know that a gastric hyperplastic polyp may associate with gastric xanthoma, although such association is very rare.
