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

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.

Delayed Biliary Hemorrhage due to Pseudoaneurysm Rupture Caused by Migration of Placed Plastic Stent After Endoscopic Ultrasound‐Guided Hepaticogastrostomy

DEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Endoscopic ultrasound‐guided hepaticogastrostomy (EUS‐HGS) is an effective method for cases where transpapillary approaches to pancreato‐biliary diseases are challenging, though serious complications often occur. Here, we report an extremely rare case of delayed biliary hemorrhage due to pseudoaneurysm rupture after EUS‐HGS, caused by ...

Orthodontic Open-Coil Spring Deactivation Forces Differ with Varying Activation Levels [PDF]

, 2018
Coil springs are used in orthodontics to deliver forces to move teeth. However, the optimal amount of activation to produce predictable, continuous deactivation forces, for the purpose of orthodontic tooth movement, is unclear.

Efficacy of the Stent‐in‐Stent Technique as a Rescue Method for Removing Embedded Metallic Biliary Stents

DEN Open, Volume 6, Issue 1, April 2026.
The stent‐in‐stent technique involves placing another fully covered metal stent inside an irremovable embedded stent to compress tissue and enable safe removal. In this study of 17 patients, the overall technical success rate was 76.5%, with higher efficacy via EUS‐guided hepaticogastrostomy (100%) and transpapillary routes (80%).
