A case of duodenal pyloric gland adenoma with high‐grade dysplasia arising from ectopic gastric mucosa

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Superficial non‐ampullary duodenal epithelial tumor is a rare disease, but its frequency has reportedly been increasing in recent years. We report a case of duodenal pyloric gland adenoma with high‐grade dysplasia arising from ectopic gastric mucosa.

Capsule Endoscopy in Inflammatory Bowel Disease: Current Status and Issues in Clinical Practice

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Inflammatory bowel diseases include Crohn's disease (CD) and ulcerative colitis (UC), both of which require endoscopic evaluation of mucosal surfaces. Capsule endoscopy has been used in clinical practice since 2000 as a minimally invasive means of mucosal evaluation.

Successful Endoscopic Submucosal Dissection for Giant Inflammatory Fibroid Polyp in Terminal Ileum

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A 55‐year‐old woman presented with postprandial abdominal pain and diarrhea. Contrast‐enhanced abdominal computed tomography revealed a large tumor in the ileocecal region. Colonoscopy demonstrated a pedunculated polyp originating from the terminal ileum, intermittently prolapsing into the cecum with a stalk‐like base.

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.

Cost‐Effectiveness Analysis of Fecal Immunochemical Test‐ and Colonoscopy‐based Colorectal Cancer Screening across Varying Uptake Rates

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives To reduce the burden of colorectal cancer (CRC), identifying cost‐effective screening strategies with particular attention to screening adherence is essential. We aimed to assess the cost‐effectiveness of screening strategies using fecal immunochemical test (FIT) and/or total colonoscopy (TCS) through simulation model analyses using

Clinicopathological Features of Superficial Non‐Ampullary Duodenal Epithelial Tumors Involving Brunner's Glands

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Background and Aims Although Brunner's glands (BGs), located in the submucosa of the duodenum, may be involved by tumor cells of superficial non‐ampullary duodenal epithelial tumors (SNADETs), the detailed incidence and histopathological features have not yet been analyzed. This study aimed to clarify the histopathological relationship between

KRAS‐G12C: The neglected biomarker to detect patients with MUTYH‐associated polyposis

International Journal of Cancer, Volume 158, Issue 6, Page 1588-1598, 15 March 2026.
What's new? MUTYH‐associated polyposis is an underdiagnosed recessive syndrome that predisposes individual to colorectal cancer and frequently displays KRAS‐G12C mutations. By analyzing a large cohort of colorectal cancer patients routinely tested for KRAS, the authors assessed whether KRAS‐G12C detection could serve as a pre‐screening tool for the ...
