Duct-to-duct biliary reconstruction following liver transplantation for primary sclerosing cholangitis

The biliary complications in patients undergoing biliary reconstruction by duct-to-duct (D-D) anastomosis or with a Roux-en-Y loop (RL) at the time of liver transplantation for primary sclerosing cholangitis (PSC, 16 D-D, 10 RL) or primary biliary cirrhosis (PBC, 31 D-D, 1 RL) were reviewed and compared. Patients were followed up for a mean period of 32 months. Extrahepatic biliary strictures occurred in 18.7%, 10% and 9.7% of DD-PSC, RL-PSC and DD-PBC patients, respectively, leaks in 6.2%, 20% and 6.4% DD-PSC, RL-PSC and DD-PBC patients, respectively (P=NS). Four intrahepatic biliary abnormalities developed in the PSC group. Duct-to-duct anastomosis did not significantly increase the risk of stricture formation or bile leaks in PSC patients compared to PBC patients. We conclude that duct-to-duct biliary reconstruction following liver transplantation for PSC is satisfactory unless the distal common bile duct is strictured.
