Long‐term results of palliative placement of very low‐axial force self‐expandable metallic stents for malignant colorectal obstruction

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Objectives Stent placement is a standard option for palliative decompression in patients with malignant colorectal obstruction. Long‐term stent placement is associated with perforation, migration, and stent occlusion. Perforation is associated with life expectancy.

Prevention of Adverse Events in Endoscopic Ultrasound‐Guided Biliary Drainage

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Endoscopic ultrasound‐guided biliary drainage (EUS‐BD) is used when biliary drainage using endoscopic retrograde cholangiopancreatography fails. Recently, it has been adopted as a primary biliary drainage method, and its indications have expanded.

Endoscopic Retrograde Cholangiopancreatography‐guided Biliary Drainage with Duckbill‐type Anti‐reflux Metal Stent versus Endoscopic Ultrasound‐guided Hepaticogastrostomy for Malignant Distal Biliary Obstruction in Pancreatic Cancer with Duodenal Invasion

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Background Duodenal invasion is a risk factor for early recurrent biliary obstruction (RBO) due to the increased risk of duodenobiliary reflux. Transpapillary biliary drainage using anti‐reflux metal stents (ARMS) and endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) are two different strategies for this condition.

Factors Affecting Clinical Course of Postoperative Bile Leakage and Efficacy of Endoscopic Biliary Drainage: A Multi‐Center Retrospective Cohort Study

DEN Open, Volume 6, Issue 1, April 2026.
Abstract Introduction Bile leakage is one of the complications after hepatobiliary surgery, causing intra‐abdominal infections, and is sometimes difficult to treat. The purpose of our study was to investigate the factors related to severity and to evaluate the efficacy of endoscopic treatment.

Role of Endoscopic Ultrasound‐guided Gastroenterostomy for Benign Gastric Outlet Obstruction

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Benign gastric outlet obstruction (GOO) often results from intrinsic conditions like peptic strictures, caustic‐induced stricture, and surgical anastomoses, and extrinsic conditions like pancreatitis, hematoma, and superior mesenteric artery syndrome.

Efficacy and Safety of Duodenal Stenting for Malignant Gastric Outlet Obstruction: Insights From a 15‐year Single‐Center Experience

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Endoscopic duodenal stent (DS) placement has become a primary palliative approach for malignant gastric outlet obstruction (MGOO), offering minimally invasive symptom relief. However, complications and risk factors for stent dysfunction and prognostic indicators of survival are not fully elucidated.

Efficacy of Drainage Combining Endoscopic Retrograde Cholangiopancreatography With Endoscopic Ultrasound‐guided Biliary Drainage for Difficult‐to‐Control Cholangitis in Patients With Hilar Cholangiocarcinoma

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Objectives Hilar cholangiocarcinoma often results in repeated early stent dysfunction and difficult‐to‐control cholangitis after drainage using endoscopic retrograde cholangiopancreatography (ERCP). In this study, we evaluated the effectiveness of additional drainage using endoscopic ultrasound‐guided biliary drainage (EUS‐BD) in patients with
