The purpose of this study is to document stent functionality and practice patterns in Canada pertaining to indications for use and stent type selection for self-expanding biliary metal stents (SEMS) when used per standard of practice.
This study is designed to provide a report of these features related to the use of WallFlex metal biliary stents used per standard of practice in Canada.

This is a a prospective study of the WallFlex™ Biliary Partially-covered Stent designed to collect data to support regulatory clearance by the FDA in the United States and to determine t...
The purpose of this study is to demonstrate non-inferiority of Fully Covered biliary SEMS to Uncovered biliary SEMS in biliary drainage for the pre-operative management of biliary obstruct...
The purpose of this study is to establish clinical proof of concept of temporary indwell of the WallFlex™ Esophageal Fully Covered Metal Stent (FCMS) for the treatment of refractory ben...
The purpose of this study is to compare the duration of stent patency of a covered vs. an uncovered biliary self-expandable metal stents (SEMS) placed to relieve biliary obstruction in pat...
The purpose of this study is to compare the duration of stent patency between partially covered and fully covered SEMS for palliation of malignant distal bile duct obstruction.
The placement of a self-expandable metal stent (SEMS) is widely used in patients with unresectable malignant biliary obstructions, but SEMSs are susceptible to occlusion by tumor ingrowth or overgr...
The usefulness of newly modified fully covered metallic stent of 12 mm in diameter and anti-migration feature for periampullary malignant biliary strictures: comparison with conventional standard metal stent.
Fully covered self-expandable metal stent (FCSEMS) are preferred for distal malignant biliary stricture (MBS). However, stent migration is a major adverse event of FCSEMS, especially for far distal MB...
Use of fully covered self-expandable metal stents (FCSEMS) for biliary drainage of malignant hilar biliary strictures is limited because of risk of cholangitis due to side branch obstruction. The aim ...
Acute biliary conditions include cholangitis, obstruction, and biliary leakage. All these conditions may lead to severe biliary sepsis, which can be life threatening. Infected obstructed cholangitis i...
Biliary atresia represents the most common surgically treatable cause of cholestasis in newborns. If not corrected, secondary biliary cirrhosis invariably results.
Abnormal passage in any organ of the biliary tract or between biliary organs and other organs.
Chronic inflammatory disease of the BILIARY TRACT. It is characterized by fibrosis and hardening of the intrahepatic and extrahepatic biliary ductal systems leading to bile duct strictures, CHOLESTASIS, and eventual BILIARY CIRRHOSIS.
Infection of the biliary passages with CLONORCHIS SINENSIS, also called Opisthorchis sinensis. It may lead to inflammation of the biliary tract, proliferation of biliary epithelium, progressive portal fibrosis, and sometimes bile duct carcinoma. Extension to the liver may lead to fatty changes and cirrhosis. (From Dorland, 27th ed)
Tumors or cancer in the BILIARY TRACT including the BILE DUCTS and the GALLBLADDER.
A motility disorder characterized by biliary COLIC, absence of GALLSTONES, and an abnormal GALLBLADDER ejection fraction. It is caused by gallbladder dyskinesia and/or SPHINCTER OF ODDI DYSFUNCTION.
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. &...
