[Problems in the reconstruction of bile flow in orthotopic liver transplantation].

In hepatic transplantation complications of the biliary drainage were frequently observed. Ischemia of the extrahepatic bile duct which occurs for anatomical reasons can cause necrosis of the bile duct. The reconstruction of biliary drainage by biliodigestive anastomosis results in ascending infections of the graft. Biliary sludge could obstruct the intra- or extrahepatic bile duct. Recently, operation methods are mainly applied in which the function of Oddi's sphincter is preserved, i.e. choledocho-choledochostomy or gallbladder conduit method. If it is not possible to perform these methods the Roux-y-jejunum loop is used. Finally, an immediate operative revision of the biliary drainage is indicated if its complication is diagnosed.
