Is Gastric Xanthelasma an Alarming Endoscopic Marker for Advanced Atrophic Gastritis and Intestinal Metaplasia?

Background/aim: The clinical significance of gastric xanthelasmas is unknown. We conducted a case-control study in order to evaluate whether gastric xanthelasma is an indicator of advanced atrophic gastritis and intestinal metaplasia.

Material And Method: The study was conducted among 1400 patients who underwent elective upper endoscopy.

Prevalence of advanced histologic features in diminutive colon polyps.

Background/aims: Accurate in vivo differentiation of colon polyp histology may serve to prevent the resection of diminutive hyperplastic polyps in the distal colon or the need for histologic assesment of diminutive polyps after resection. The clinical implementation of these strategies depends on the prevalence of advanced histologic findings among diminutive polyps. We aimed to determine the prevalence of advanced histologic features (villous features, high-grade dysplasia, and adenocarcinoma) in diminutive colon polyps and compare it to small and larger polyps.
