This is a non-inferiority randomized study to compare a plastic stent without central lumen (VIADUCT) with self-expandable metal stents for treatment of malignant obstruction of the common bile duct. It is a non-interventional study, a CE mark for the VIADUCT stent exists.

The primary purpose is to compare patency of two different types of biliary metal stents, i.e. covered versus uncovered Nitinella metal stent. Secondary purposes are to determine frequency...
The aim of this study is to determine whether administration of aspirin can help maintain the patency of metallic stents for distal malignant common bile duct obstruction. Metal stents are...
Previous studies indicated that covered stents are less likely to become occluded in comparison to bare stents. While the probability of occlusions caused by tumor in-growth is less in cov...
Endoscopic insertion of plastic or metal stents in introhepatic bile duct under endoscopic retrograde cholangiopancreatography is a well established treatment of malignant or benign biliar...
The overall median survival of nonresectable malignant hilar obstruction in most series has been less than 6 months. Most patients with malignant hilar obstruction present with advanced di...
The stent length as well as the stent overlap for the percutaneous treatment of diffuse coronary disease have been considered predictors of adverse events. However, there are no comparative data on th...
The optimal treatment of in-stent restenosis (ISR) remains unknown. This study evaluates the efficacy and safety of a paclitaxel coated balloon compared to a 2nd generation sirolimus eluting stent in ...
Coronary drug-eluting stent development has introduced new metal alloys, changes in stent architecture and bioresorbable polymers. Whether these advancements improve long-term clinical safety and effi...
The purpose of this study was to determine accuracy and necessity of long-term Doppler ultrasound (DU) surveillance of transjugular intrahepatic portosystemic shunt (TIPS) patency after implantatio...
Drug-eluting stent (DES) strut fracture (SF) is associated with higher incidence of In-stent restenosis (ISR)-return of blockage in a diseased artery post stenting-than seen with bare metal stents (BM...
Stents that are covered with materials that are embedded with chemicals that are gradually released into the surrounding milieu.
Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.
Methods for assessing the patency of the fallopian tubes.
Neutral or negatively charged ligands bonded to metal cations or neutral atoms. The number of ligand atoms to which the metal center is directly bonded is the metal cation's coordination number, and this number is always greater than the regular valence or oxidation number of the metal. A coordination complex can be negative, neutral, or positively charged.
Proteases which use a metal, normally ZINC, in the catalytic mechanism. This group of enzymes is inactivated by metal CHELATORS.
A stent is a small mesh tube that's used to treat narrow or weak arteries. Arteries are blood vessels that carry blood away from your heart to other parts of your body. A stent is placed in an artery as part of a procedure called angioplasty. &...
