Diagnosis and treatment of gastric abscess by endoscopic ultrasound: A mini‐review of the preliminary application

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Gastric abscess is a rare condition caused by gastric barrier damage. It is easily misdiagnosed in clinical practice as a cancer recurrence or submucosal tumor, especially after surgery or endoscopic submucosal dissection. With a relatively high mortality rate, the cause and clinical characteristics of gastric abscesses are obscure.

Visibility Evaluation of Fundic Gland Polyp Associated With Proton Pump Inhibitor in Texture and Color Enhancement Imaging

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives A ‘gray color sign’ (GCS) is a new endoscopic feature of fundic gland polyp associated with proton pump inhibitor (PPI‐FGP). Here, we compare the ability of texture and color enhancement imaging (TXI) to white light imaging (WLI) with regard to the detection of GCS. Methods In this prospective study, 19 consecutive patients with PPI‐

Current Status of Gastric Cancer Screening and Future Perspectives

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Gastric cancer (GC) remains a major global health concern, particularly in East Asia, Central Asia, and Eastern Europe, where its incidence and mortality rates are high. Helicobacter pylori infection is the primary cause of GC and leads to carcinogenic progression from nonatrophic gastritis to cancer.

Vedolizumab Induces Remission in Two Cases of Ulcerative Colitis With Upper Gastrointestinal Involvement

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Ulcerative colitis (UC) predominantly affects the colon; upper gastrointestinal involvement (UGI) has been reported, but no established treatments exist. We report two cases of UC with concomitant UGI that showed positive responses to vedolizumab therapy.

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.
