Somatic Mosaic AXIN2‐associated Colonic Polyposis Predominantly Involving the Proximal Colon: A Case Report

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Colonic adenomatous polyposis is most commonly caused by germline pathogenic variants in the APC gene; however, recent genetic studies have identified patients without APC mutations. AXIN2‐associated colonic polyposis is a rare condition related to dysregulation of the Wnt/β‐catenin signaling pathway. Most reported cases have involved germline

Clinical Outcomes of Multi‐Hole Covered Self‐Expandable Metal Stents for Malignant Distal Biliary Obstruction: A Retrospective Comparative Study With an Exploratory Evaluation of 6‐mm Devices

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Covered self‐expandable metal stents (CSEMS) are widely used for malignant distal biliary obstruction (MDBO), but cholecystitis, post‐endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP), stent migration, and recurrent biliary obstruction (RBO) remain clinically important limitations.

Association of Propofol Versus Midazolam Sedation With Successful Pharyngeal Observation During Upper Gastrointestinal Endoscopy: A Retrospective Study

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Adequate pharyngeal observation during esophagogastroduodenoscopy (EGD) is increasingly recognized as an important component of high‐quality upper gastrointestinal endoscopy. However, visualization may be impaired by gag reflexes and patient movement.

Comparative Diagnostic Sensitivity of Endoscopic Ultrasound‐guided Tissue Acquisition for Hepatocellular Carcinoma Versus Intrahepatic Cholangiocarcinoma

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Background and Aims Accurate histological differentiation between hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) is essential for selecting appropriate treatment. Endoscopic ultrasound‐guided tissue acquisition (EUS‐TA) is increasingly used for focal liver lesions; however, comparative data on its diagnostic ...
