Article Synopsis
- - This study investigates the link between multiple white and flat elevated lesions (MWFL) in the stomach and the use of oral proton pump inhibitors (PPIs), finding a significant association between the two.
- - Out of 163 patients, those taking oral PPIs had a much higher occurrence of MWFL (49.3%) compared to those not on PPIs (10.9%), with results showing a strong statistical significance (p<0.001).
- - The research suggests that oral PPI intake is a significant independent risk factor for the presence of MWFL, indicating a potential clinical concern for patients using these medications.
Article Synopsis
- Patients with incomplete gastric intestinal metaplasia (GIM) have a higher risk of gastric cancer, and this study aims to investigate the effectiveness of micromucosal patterns observed during magnifying endoscopy with narrow-band imaging (M-NBI) in diagnosing incomplete GIM.
- The research involved 98 patients, focusing on specific regions of the stomach and using endoscopic findings to classify GIM patterns, followed by targeted biopsies for histological analysis.
- Results indicated that while micromucosal patterns weren't useful for diagnosing GIM subtype, the presence of white opaque substance (WOS) was a strong predictor for identifying incomplete GIM, showing high specificity and moderate sensitivity.

A white opaque substance (WOS) has been observed in the epithelia of gastric, duodenal, and colorectal epithelial adenomas and carcinomas, using magnifying endoscopy (ME). The WOS has been reported to be derived from a dense accumulation of minute lipid droplets in the epithelium. This study aimed to investigate whether the WOS in colorectal hyperplastic polyps was derived from lipid droplets accumulated in the epithelium, as observed in the case of gastric, duodenal, and colorectal epithelial neoplasms.

Therefore, we conducted a study to determine the usefulness of magnifying endoscopy using vessel plus surface classification system for making a diagnosis of early gastric cancer after eradication.
Method: Usefulness of the markers of the vessel plus surface classification system for diagnosing gastric cancer using magnifying endoscopy with narrow-band imaging was investigated for gastric cancer detected after eradication (-eradicated group) vs.
Background/aims: The objective of this study was to elucidate the histological structure of the absent microsurface patterns (MSPs) that were visualized by magnifying endoscopy with narrow-band imaging (M-NBI).
Methods: The study included consecutive gastric epithelial neoplasias for which M-NBI findings and histological findings could be compared on a one-to-one basis. The lesions were classified as absent MSPs and present MSPs based on the findings obtained using M-NBI.
Background/aims: While the occurrence of multiple whitish flat elevated lesions (MWFL) was first reported in 2007, no studies on MWFL have been published to date. The present retrospective observational study aimed to clarify the endoscopic findings and clinicopathological features of MWFL.
Methods: Subjects were consecutive patients who underwent upper gastrointestinal endoscopy as part of routine screening between April 2014 and March 2015.
