[Conservative and interventional endoscopic therapy of biliary tract carcinoma]

Endoscopic therapy is central to the palliative treatment of bile duct carcinoma. In obstructive jaundice, biliary drainage has few complications and relieves symptoms reliably. It can prevent further complications and is indispensable to the treatment of cholangitis. The principal drawback of biliary stents is stent occlusion and cholangitis. Prophylactic antibiotics were not proven to be effective. Technical details concerning material, number and location of stents await further clarification. Photodynamic therapy is an emerging adjunct to palliative therapy of biliary cancer. Preoperative biliary drainage in obstructive jaundice is not warranted as a routine intervention. It may be indicated, though, as preoperative bridging or to allow liver function to recover before major hepatic surgery. Finally, stenting of postoperative bile duct stenosis is gaining increasing acceptance.
