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 ...

Efficacy and Safety of a Revised Gastric Peroral Endoscopic Myo‐Neurotomy Procedure for Bariatric Endoscopy in a Porcine Model

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background Endoscopic sleeve gastroplasty is a minimally invasive and effective treatment for obesity, although gastric mucosa folding and subsequent reduced visibility of the gastric lining raise concerns for some patients. This study evaluates the safety and efficacy of a revised peroral endoscopic myo‐neurotomy (R‐POEM‐N) technique using a ...

Diagnostic Concordance Using Japan Narrow‐band Imaging Expert Team Classification for Diagnosing Colorectal Neoplasms: A Web‐based Diagnostic Concordance Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives The Japan Narrow‐band Imaging Expert Team (JNET) classification is widely used for magnified endoscopic diagnosis of colorectal neoplasms. However, its diagnostic concordance, particularly among the core members who contributed to its development, has not been sufficiently evaluated.

Safety Profile of Low‐Power Pure‐Cut Hot Snare Polypectomy for 10–14 mm Nonpedunculated Colorectal Neoplasms

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives The reported rate of delayed bleeding (DB) after hot snare polypectomy (HSP) for 10–19‐mm polyps is 2.1%–2.8%, which is non‐negligible. We hypothesized that a low‐power pure‐cut current (LPPC) yields a lower risk of DB than a coagulation current, and we evaluated the safety of LPPC HSP for colorectal polyps.

White Light, Magnifying Endoscopy, Endocytoscopy, and Artificial Intelligence in Diagnosis of Early Colorectal Cancer: A Comparative Study

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Early detection of colorectal cancer is critical for improving prognosis. However, assessing invasion depth—distinguishing between superficial cancer (T1a) and deep submucosal invasive cancer (T1b)—remains challenging. Recently, artificial intelligence (AI)‐assisted computer‐aided diagnosis (CADx) systems have been introduced to ...

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.

Feasibility Study of Modified Underwater Endoscopic Mucosal Resection for Colorectal Polyps

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Underwater endoscopic mucosal resection (UEMR) is widely performed for colorectal tumors. However, in our experience, it is sometimes difficult to keep a clear endoscopic view underwater, due to dirty fluid inflow or insufficient water pooling after grasping the polyp, or bleeding just after endoscopic resection.

Utility of Combined Indigo Carmine and Red Dichromatic Imaging for Pit Pattern Diagnosis in Colorectal Lesions: A Comparison with Crystal Violet

DEN Open, Volume 6, Issue 1, April 2026.
With indigo carmine alone, pits appear navy blue and the surrounding mucosa pale red, colors roughly 90° apart on the color wheel. In contrast, IC + RDI renders pits violet and mucosa yellowcomplementary colors positioned 180° apart. This stronger chromatic contrast enhances visual discrimination, improving visibility score (3.17 vs.

Evaluation of Visibility With an Eye‐tracking System: Effectiveness of Narrow‐Band Imaging for Detecting Colorectal Adenoma and Serrated Lesions

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Image‐enhanced endoscopy may reduce colorectal cancer mortality by improving lesion detection. Narrow‐band imaging and texture and color enhancement imaging are widely used, but their diagnostic efficacy compared with white light imaging remains unclear.

Maternal RSV vaccination for infant protection: A systematic review and meta‐analysis of phase 3 trials with an integrated economic evaluation

International Journal of Gynecology &Obstetrics, Volume 173, Issue 1, Page 63-73, April 2026.
Abstract Background Respiratory syncytial virus (RSV) is a leading cause of hospitalization and mortality in early infancy. Maternal immunization offers a preventive strategy, but uncertainties regarding safety and economic value have limited its implementation.
