Gastric Foveolar‐Type Hyperplastic Polyp of the Duodenum With GNAS and KRAS Mutations: A Potential Precursor to Neoplasia

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT We report a gastric foveolar‐type hyperplastic polyp of the duodenum harboring mutations in the GNAS and KRAS genes. The lesion was incidentally detected during a routine upper gastrointestinal endoscopy in a man in his 50s. It appeared as a 10‐mm elevated lesion located at the superior duodenal angle.

Efficacy and Safety of Gel Immersion Endoscopic Mucosal Resection for Gastric Neoplasms in Patients With Familial Adenomatous Polyposis: A Multicenter Retrospective Study

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Approximately 10%–30% patients with familial adenomatous polyposis (FAP) develop gastric neoplasms (GNs). Although recent reports have suggested the effectiveness of gel‐immersion endoscopic mucosal resection (GI‐EMR) for FAP‐associated GNs, given its simplicity and safety, treatment outcomes for such lesions have not been evaluated.

Trends in Endoscopist Reporting Rates of Eosinophilic Gastrointestinal Diseases in Japan Evaluated by the Japan Endoscopy Database Project

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
We analyzed 9,940,870 endoscopic procedures from the Japanese Endoscopy Database (2015–2023), identifying 9,669 eosinophilic gastrointestinal disease (EGID) cases. The prevalence of eosinophilic esophagitis, gastritis, and duodenitis increased significantly (p < 0.001), while enteritis and colitis remained unchanged (p = 0.136). EoE rose from 36 cases (
