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

open access: yesDEN 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.

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

open access: yesDEN 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.

Advancements and limitations of image‐enhanced endoscopy in colorectal lesion diagnosis and treatment selection: A narrative review

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
Abstract Colorectal cancer (CRC) is a leading cause of cancer‐related mortality, highlighting the need for early detection and accurate lesion characterization. Traditional white‐light imaging has limitations in detecting lesions, particularly those with flat morphology or minimal color contrast with the surrounding mucosa.

A Case of Gastric Atypical Lipomatous Tumor/Well‐Differentiated Liposarcoma With Endoscopic Morphological Changes

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Atypical lipomatous tumor/well‐differentiated liposarcoma is a locally aggressive mesenchymal neoplasm composed of adipocytes and stromal cells. Gastric cases are exceedingly rare, and their malignant potential remains unclear. We report a case of a woman in her 60s who was found to have multiple submucosal tumor‐like lesions of the stomach ...

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

open access: yesDEN 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‐

Artificial Intelligence‐assisted Endoscopy and Examiner Confidence: A Study on Human–Artificial Intelligence Interaction in Barrett's Esophagus (With Video)

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objective Despite high stand‐alone performance, studies demonstrate that artificial intelligence (AI)‐supported endoscopic diagnostics often fall short in clinical applications due to human‐AI interaction factors. This video‐based trial on Barrett's esophagus aimed to investigate how examiner behavior, their levels of confidence, and system ...

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

open access: yesDEN 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.

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

open access: yesDEN 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.

The Risk of Colonoscopy‐related Bleeding in Patients With or Without Continued Treatment With an Antithrombotic Agent

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives We prospectively investigated the risk of colonoscopy‐related bleeding in relation to antithrombotic treatment. Methods This prospective, observational, single‐center cohort study (NCT02594813) enrolled consecutive patients who underwent colonoscopy, including the removal of colorectal polyps, regardless of the continuation of ...
