biliary endoprosthesis versus plastic stents
trial of Wallstent biliary endoprosthesis versus plastic stents .
The procedures performed in our series were mostly stone removal (=29), and the others included plastic biliary stent insertion due to cancer such as pancreatic cancer, bile duct cancer, and metastatic lymphadenopathy or benign biliary stricture such as chronic pancreatitis or Mirizzi syndrome (=6), diagnostic approach for liver enzyme elevation such as cholecystitis or cholangitis (=10), and metal stent insertion due to Klastkin's tumor (=1) ().
plastic versus metal biliary stents ..
Recent advances in development of endoprosthesis have led to the development of fully covered self-expanding metal stents (FCSEMs) which are coated circumferentially with a material that prevents stent occlusion due to bacterial colonization, tissue hyperplasia, and tumor in growth thereby increasing the duration of stent patency in BBS and bile leaks.
