Interventional treatment of obstructive jaundice

  Obstructive jaundice is a generalized yellowing —- jaundice caused by poor bile drainage in the ductal lumen due to some lesion in one part of the intrahepatic and extrahepatic bile ducts, which stagnates in the bile ducts and returns to the blood. The so-called intrahepatic and extrahepatic bile ducts include the intrahepatic bile duct, left and right hepatic ducts, common hepatic duct, cystic duct, common bile duct and gallbladder, these structures are the necessary route for bile to enter the duodenum, a lesion in any part of the bile duct may lead to poor bile drainage, elevated bile pigment (direct) content in the blood, deposition of bile pigment on the skin and sclera, making its color yellow, i.e. jaundice, as well as systemic biochemical disorders, which are life-threatening.  Depending on the etiology, different surgical methods are available, such as: surgical open surgery, laparoscopy, ERCP, percutaneous percutaneous hepatic biliary drainage (PTCD) and endobiliary stenting.  Percutaneous percutaneous hepatic biliary drainage (PTCD) and endobiliary stent implantation are commonly used in elderly and frail patients with advanced cancer jaundice, as well as in pre-adjuvant treatment that requires surgical intervention.  This interventional therapy is safe and simple, performed under local anesthesia with fine needle puncture, and does not affect daily life after the procedure.
