Direct observation of an exposed blood vessel in a colonic diverticulum using ultrathin endoscopy

DEN Open
In recent years, cases of diverticular bleeding have become more common. Although identifying the bleeding diverticulum is difficult, it is even more difficult to identify the exposed blood vessels in the bleeding diverticulum.

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.

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).

Pre‐ and post‐diagnostic meat intake in relation to risk of recurrence and mortality among individuals with stage I–III colorectal cancer

International Journal of Cancer, Volume 158, Issue 4, Page 895-908, 15 February 2026.
What's new? Processed meat and unprocessed red meat intakes are associated with increased colorectal cancer risk. However, evidence on their associations with mortality after colorectal cancer diagnosis is inconsistent. This study examined associations between three meat types, including unprocessed poultry, and the risk of recurrence and all‐cause ...
