Diagnostic Performance of Magnifying Endoscopy With Crystal Violet Staining for Superficial Non‐ampullary Duodenal Epithelial Tumors: A Single‐center Prospective Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives We previously reported a potential diagnostic algorithm for superficial non‐ampullary duodenal epithelial tumors (SNADETs) using white‐light magnifying endoscopy with crystal violet staining (ME‐CV). This study aimed to determine the diagnostic performance of the scheme and compare it with the conventional white‐light endoscopy (WLE)

Underwater Endoscopic Mucosal Resection as a Salvage Strategy for a Non‐Lifting Early Sigmoid Colon Carcinoma After Failed Conventional Endoscopic Mucosal Resection: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Endoscopic mucosal resection (EMR) has been widely adopted as an endoscopic treatment for colorectal tumors. However, in non‐lifting lesions, EMR often becomes technically challenging, leading to piecemeal resection or residual tumor. Recently, underwater EMR (UEMR) has been developed as a novel technique that allows mucosal and submucosal ...

Polyglycolic Acid Sheet Application to Refractory Delayed Bleeding After Rectal Endoscopic Submucosal Dissection: A Case Report

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A man in his 50s underwent endoscopic submucosal dissection (ESD) for a rectal tumor measuring 28 mm. He was not taking any antithrombotic medication. On the third, 11th, 18th, and 24th days after the procedure, bleeding was observed from different areas of the ulcer bed margin and was managed with hemostatic forceps.

Short‐Term Efficacy and Long‐Term Limitations of Self‐Expandable Metallic Stent Placement for Colorectal Obstruction due to Extracolonic Malignancies

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objectives Although previous studies have investigated colonic stenting for obstruction due to extracolonic malignancies (ECMs), long‐term data—especially concerning quality of life and chemotherapy resumption—remain insufficient. Methods Clinical data of 25 patients with ECM‐induced colorectal obstruction were retrospectively analyzed.

Comparison of Detection Yields Between Texture and Color Enhancement Imaging Mode 1 and Mode 2 for Colorectal Lesions: A Post‐hoc Analysis of a Multicenter Observational Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Colonoscopy is a reliable technique for the detection, diagnosis, and treatment of adenomas and early cancer. Image‐enhanced endoscopy (IEE) is important for detecting colorectal lesions. Texture and color‐enhancement imaging (TXI) has recently emerged as a novel modality for IEE.

Adalimumab‐responsive Monogenic Inflammatory Bowel Disease With Pseudopolyposis Characteristic of TGFBR2 Variant in Loeys‐Dietz Syndrome

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Loeys‐Dietz syndrome (LDS) is an autosomal dominant connective tissue disorder caused by pathogenic variants in TGFBR1 or TGFBR2. It is characterized by vascular fragility, skeletal abnormalities, and predisposition to allergic and inflammatory conditions, including monogenic inflammatory bowel disease (IBD).
