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

DEN 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

DEN 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

DEN 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 (

Severe Gastroduodenitis Associated With Ulcerative Colitis After Total Colectomy Successfully Treated With Endoscopic Hemostasis and Oral Tacrolimus

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Herein, we report a rare case of gastroduodenitis associated with ulcerative colitis (UC). A 42‐year‐old man was diagnosed with UC 1 year prior to admission to our hospital. The patient underwent a 3‐stage total colectomy and ileal pouch‐anal anastomosis for severe UC.

Intramucosal Alpha‐Fetoprotein‐producing Early Gastric Cancer Without Vascular Invasion or Metastasis Diagnosed After Endoscopic Submucosal Dissection: A Case Report and Literature Review

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Alpha‐fetoprotein‐producing gastric cancer (AFPGC) is a rare histological subtype of gastric cancer that is often diagnosed at an advanced stage. In the present case, an elevated lesion was detected in the gastric antrum during upper gastrointestinal endoscopy screening and diagnosed as early gastric cancer of cT1a.
