“Cat scratch colon” causing cecal perforation as a rare complication due to barotrauma during colonoscopy: A case report and literature review

DEN Open, Volume 6, Issue 1, April 2026.
Abstract “Cat scratch colon” (CSC), characterized by spontaneous bright‐red linear markings or mucosal laceration with bleeding due to air insufflation barotrauma, is a rare complication during colonoscopy. These mucosal lacerations can present as superficial tears that do not generally have clinical repercussions or as deeper tears that damage the ...

Rectal metastasis from lung cancer diagnosed by endoscopic ultrasound‐guided fine needle biopsy: A case report

DEN Open, Volume 6, Issue 1, April 2026.
Abstract A 73‐year‐old man visited our hospital due to hyperintestinal peristalsis and diarrhea. He had been undergoing regular annual checkups for dust lung disease. Contrast‐enhanced computed tomography scan showed edematous thickening of the rectal wall with contrast effect.

Assessing the effectiveness of texture and color enhancement imaging versus white‐light endoscopy in detecting gastrointestinal lesions: A systematic review and meta‐analysis

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Introduction Gastrointestinal cancers account for 26% of cancer incidence and 35% of cancer‐related deaths globally. Early detection is crucial but often limited by white light endoscopy (WLE), which misses subtle lesions. Texture and color enhancement imaging (TXI), introduced in 2020, enhances texture, brightness, and color, addressing WLE's

Endoscopic features of deficient mismatch repair/microsatellite instability‐high and BRAF‐mutated colorectal cancer

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objective Recent advancements in genome analyses, including the BRAF gene and mismatch repair (MMR) gene/microsatellite instability (MSI), have revealed the biological diversity of colorectal cancer (CRC). BRAF‐mutated CRC has a poor prognosis; however, cases exhibiting deficient MMR (dMMR)/MSI‐high (MSI‐H) and BRAF gene mutations have ...

Prognostic factors and long‐term outcomes with endoscopic submucosal dissection for colorectal tumors in patients aged 75 years or older

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Background Studies regarding the long‐term outcomes of endoscopic submucosal dissection (ESD) performed in older patients with colorectal tumors are limited. Therefore, in this study, we aimed to analyze the long‐term outcomes of older patients with colorectal tumors who underwent ESD and identify prognostic factors.

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

DEN 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.

Edoxaban‐induced enterocolitis: The first case report demonstrating distinct endoscopic and histological features

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Direct oral anticoagulants (DOACs), including edoxaban, are widely used for stroke prevention in atrial fibrillation and venous thromboembolism. While gastrointestinal bleeding and diarrhea are recognized adverse effects, DOAC‐induced enterocolitis has not been established as a distinct clinical entity.

Investigation of the actual implementation of “post‐sedation discharge criteria” and “time‐out” immediately before procedure in endoscopy: A nationwide survey study in Japan

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Post‐sedation discharge criteria for outpatient endoscopy and time‐out procedures immediately before endoscopic examinations are important for ensuring patient safety. This study used a web‐based questionnaire to survey the implementation status and current situation of these practices in Japan in 2024.

Impact of Non‐Anesthesiologist‐Administered Propofol Sedation for Outpatient Endoscopy in the Healthcare System

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Introduction Non‐anesthesiologist‐administered propofol (NAAP) sedation for outpatient endoscopy has proven to be safe. However, implementing NAAP in Western countries faces challenges, and propofol‐based sedation is still largely administered by anesthetists.

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

DEN 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.
