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 ...

Microstructure and mechanical properties of an austenite NiTi shape memory alloy treated with laser induced shock

, 2013
In this study, microstructure and mechanical properties of an austenite NiTi alloy treated with laser shock peening (LSP) was investigated. It was found that the thickness of shock affected layer is about 250-300 μm.

Functional behavior of pseudoelastic niti alloy under variable amplitude loading [PDF]

, 2020
Cyclic loading of superelastic NiTi shape memory alloy (SMA) causes forward and reverse austenite–martensіte transfor-mations, and also increases the volume of stabilized martensite. This appears in the change of stress-strain curve form, the decrease of

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.
