Magnified Observation of Elevated Borderline Lesions (Adenoma) of the Stomach Based on Dissecting Microscopy and Magnifying Fiberoptic Endoscopy

Gastric Mucosal Surface In Cirrhosis Evaluated By Magnifying Endoscopy And Scanning Electronic Microscopy

“…An improved and detailed description with increased magnification was confirmed in this study by two results on the prevalence of "pooled" gastric areas (gastric areas or mosaic pattern) (see Table 3): a) magnifying endoscopy identified pooled gastric areas in the gastric body of control patients and in the antrum of cirrhotic patients more frequently than conventional endoscopy ( Table 3); b) whereas conventional endoscopy showed a significant increase in the prevalence of pooled gastric areas in the body of cirrhotic patients compared with control patients (Table 3), microendoscopy, by identifying more pooled gastric areas in control patients, did not show a difference in prevalence between the two patient groups. It should be noted that convoluted ridges, whose furrows correspond to pits, have been also termed a sulciolar pattern and have mainly been observed in the antrum [21], as in our study.…”

“…Thus the gastric mucosal surface was observed using a magnifying fibergastroscope, and the fine gastric mucosal patterns, which were even smaller than one unit of gastric area, were examined at a magnification of about 30 in 1978 [19]. Okada & Nishizawa have established a classification of elevated lesions of the stomach with the magnifying fiberoptic endoscope [20] which has been applied to borderline lesions (adenoma) [21]. Magnifying endoscopy has also been useful in the diagnosis of gastric polyps by suggesting a high possibility of neoplastic polyps [22].…”

Endoscopic Submucosal Dissection for Early Gastric Cancer Using Magnifying Endoscopy With a Combination of Narrow Band Imaging and Acetic Acid Instillation

“…Until 1990, there were only a few reports of magnifying endoscopy for the upper gastrointestinal tract 10–12 . Overcoming technical problems such as low quality of the image and poor operationality has greatly increased the use of magnification endoscopy in the upper gastrointestinal tract 13 .…”

Characterization and identification of gastric hyperplastic polyps and adenomas by confocal laser endomicroscopy

“…The established CLE imaging criteria were developed on the basis of pathologic criteria [9,10], previous published research [8,[11][12][13][14][15][16], and our early experience beginning June 2006 [17][18][19]. Afterward, an endoscopic resection was performed to remove gastric polyps.…”
