Management of malignant biliary obstructions including external drainage, internal-external drainage and biliary stent implantation.

​​​​​​​Biliary drainage is a procedure that helps drain extra bile. When bile blocks the bile duct, it can back up into the liver and cause symptoms like jaundice. A biliary drain (also called a biliary stent) is a thin, hollow tube with several holes along the sides. This drain helps bile flow more easily.
