blog

Percutaneous transhepatic biliary drainage (PTBD) involves a small, flexible, and plastic tube that is placed through the skin into the liver in order to drain an obstructed bile duct system. Indication for biliary drainage is blockage or narrowing (stricture) of the bile ducts which occurs in diseases like Gallstones – in the gallbladder or within the bile ducts, inflammation of the pancreas (pancreatitis) or the bile ducts (sclerosing cholangitis), tumours of the pancreas, gallbladder, bile duct, and liver, or an injury to bile ducts during surgery. The liver secretes bile that aids the digestion of fats.
