A Case of Human Epidermal Growth Factor Receptor 2‐Positive Colon Cancer With Invasive Micropapillary Carcinoma Component

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT A female patient in her 60s tested positive for the fecal occult blood test while undergoing health screening. Colonoscopy revealed a 15‐mm‐sized flat elevated lesion with a central depression in the sigmoid colon. Narrow‐band imaging magnification revealed a Japan Narrow‐Band Imaging Expert Team classification of type 2B, whereas crystal ...

Gel‐immersion Endoscopic Submucosal Dissection for Superficial Colorectal Neoplasms: A Retrospective Study Comparing Conventional Endoscopic Submucosal Dissection

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Gel‐immersion endoscopy offers benefits such as buoyancy, traction, and a clear visual field without gas insufflation. While some case reports have described colorectal gel‐immersion endoscopic submucosal dissection (Gi‐ESD), there have been no consecutive case series. This study aimed to clarify the usefulness of Gi‐ESD.

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 ...

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.

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.

Epiploic Appendagitis Causing Small Bowel Obstruction - A Rare Case Report

Annals of Medicine and Medical Sciences
Background: Small bowel obstruction (SBO) remains a frequently encountered cause of hospital admission and surgical intervention. While postoperative adhesions are the predominant aetiology, other causes including hernias, neoplasms, and inflammatory ...

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).

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.
