This study looks in to the rate of biliary stent dysfunction for plastic and metallic stents in patients who need biliary drainage due to a tumor in pancreas before possible pancreaticoduodenectomy. Complications related to the biliary decompression, and possible post-surgical complications in all patients are also recorded.
This trial aims to confirm whether metallic biliary stents really are superior to plastic stents as some previous studies suggest. Specific patient groups are also evaluated individually to see, whether patients with ongoing cholangitis at the time of diagnosis or patients receiving neoadjuvant treatments have less stent dysfunction cases and complications with metallic stents than with plastic stents.

The aim of this study is to determine the average patency period of the new anti-reflux biliary stent on patients with malignant bile duct strictures and to determine if this stent remains...
The purpose of this prospective, randomized multicenter study is to determine whether there is any difference in stent patency of covered metallic stents in terms of stent positioning, abo...
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...
Biliary obstruction can be relieved by biliary stent. Ascending infection of biliary passage (cholangitis) causes hospitalization and obstruction of stents. Reflux of intestinal fluids thr...
Post-surgical biliary strictures are common especially after cholecystectomy. Standard treatment involves the performance of multiple procedures over a 1 year period at least using several...
Anastomotic bile duct stricture (ABS) is one of the most common complications after liver transplantation. Current practice of endoscopic retrograde cholangiopancreatography (ERCP) with multiple plast...
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 ...
The optimal approach at treating infected biliary stents at the time of cholangitis remains unknown. This study aims to compare the efficacy of stent exchange versus stent sweeping/stent-in-stent appr...
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)
Cylindrical metallic tubes that are inserted to hold open a structure in order to treat vascular, bile duct, esophageal and other tubular organ constrictions.
Tumors or cancer in the BILIARY TRACT including the BILE DUCTS and the GALLBLADDER.
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. &...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
