Improving Operator Depth Vision in Gastrointestinal Endoscopy: A Pilot Study of a New Three‐dimensional Imaging System

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background and aims Traditional two‐dimensional (2D) gastrointestinal endoscopy lacks depth perception, leading to potential diagnostic errors. This study evaluates a novel software‐based three‐dimensional (3D) endoscopy system that converts 2D images into 3D, compatible with existing endoscopes.

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.

Secondary Aortoduodenal Fistula Diagnosed after Repeated Gastrointestinal Bleeding Episodes in a Patient With Prior Aortic Graft Surgery

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Secondary aortoduodenal fistula (sADF) is a rare but life‐threatening complication after aortic graft surgery. Diagnosis is often challenging, particularly when contrast‐enhanced computed tomography (CT) and endoscopy results are inconclusive. We report a case in which diagnosis was challenging due to contrast media allergy and non‐diagnostic ...

A Rare Case of Immune‐related Adverse Events Localized to the Small Intestine

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Enterocolitis is a common gastrointestinal manifestation of immune‐related adverse events (irAEs); however, only a few studies have reported on irAE enteritis with localized active inflammation in the small intestine. Here, we report the case of a 74‐year‐old man who developed diarrhea, abdominal pain, and oral intake difficulty and was ...

Successful Colonic Stenting Across the Ileocecal Valve With Severe Malignant Stenosis Using Ultra‐thin Scope and Single‐balloon Overtube

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Self‐expanding metallic stents (SEMSs) are an established palliative option for malignant colonic obstruction, including in cases with proximal lesions. However, SEMS placement across the ileocecal valve (ICV) can be technically challenging because of the anatomical curvature and luminal stenosis. Herein, we report a successful case of colonic
