Comparison of Uncovered and Covered Biliary SEMS for the Salvage of Obstructed SEMS: A Multicenter Retrospective Propensity Score–Weighted Study

Journal of Gastroenterology and Hepatology, EarlyView.
In patients undergoing secondary SEMS placement after initial uncovered stent failure, fully covered and uncovered SEMSs showed comparable patency, survival, and safety. However, mechanisms of recurrent biliary obstruction differed by stent type, with tumor ingrowth in uncovered SEMSs and sludge or food impaction in fully covered SEMSs.

Nanoprecipitate characterisation in NiTi and aluminium alloys: A TEM‐based overview

Journal of Microscopy, EarlyView.
Abstract Nanoscale precipitates are central to the functional and mechanical performance of many advanced alloys, yet their characteristics and spatial distributions can be directly resolved only by electron microscopy. In this poster‐style article, focused ion beam‐prepared TEM lamellae are used to provide a microscopy‐focused overview of ...

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 ...
