Long‐anchoring Stent Method as a Rescue Technique for Early Dysfunction of Covered Self‐Expandable Metal Stents in Distal Malignant Biliary Obstruction: A Retrospective Case Series

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objective Covered self‐expandable metal stents (SEMS) are widely used for treating distal malignant biliary obstruction (MBO). Severe SEMS angulation can cause stent dysfunction. Placement of a long double‐pigtail plastic stent inside the SEMS (the “long‐anchoring stent method”) may straighten the angulated SEMS, thereby achieving effective ...

Comparison of Two Partially Covered Metal Stents for Endoscopic Ultrasound‐guided Hepaticogastrostomy: A Multi‐Center Retrospective Study

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is an alternative biliary drainage method after failed endoscopic retrograde cholangiopancreatography. Nevertheless, it is associated with adverse events (AEs), including peritonitis and stent migration.

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.
