In ohotopic liver transplantation, which is the best way to get bile drainage in donor liver

The preferred method biliary drainage during ohotopic liver transplantation is direct end to end anastomosis between donor common bile duct and recipient common bile duct Bile Duct anastomosis in ohotopic liver transplantation Choledochocholedochostomy(CDCD) This is end to end anastomosis donor common bile duct and recipient common bile duct This is preferred bile duct anastomosis and when the recepient bile duct not diseased Choledochojejunostomy (CDJ) This is an Roux-en-Y configuration anastomosis between the end of the common bile duct and the sidebof a loop of jejunum This is an alternative bile duct anastomosis and is performed when CDCD anastomosis is not feasible. This may be the case when the recepient extrahepatic bile duct is diseased or small or when there is significant recepient donor duct size mismatch. Ref: Blumga 5th edition Pg no : 1727-1728
