Background/Aims:
Endogenous hydrophobic bile acids are suspected to be one of the pathogenetic factors of biliary complications after orthotopic liver transplantation (OLT). This study was designed to investigate the effects of hydrophilic ursodeoxycholic acid (UDCA) administration early after OLT on serum liver tests and the incidence of biliary complications.
Methods:
112 adult patients undergoing OLT from donation after cardiac death (DCD) were randomized to UDCA (13-15 mg/kg/day for 4 weeks; 56 patients) or placebo (56 patients). Serum liver tests and serum bile acids of all patients and biliary bile acids in patients with T-tube drainage were determined during the 4 weeks after OLT. Biliary complications as well as patient and graft survival were analyzed during a mean follow-up of 41.6 months.
Results:
UDCA treatment decreased ALT, AST and GGT (p < 0.05) during the 4 weeks after OLT and the incidence of biliary sludge and casts within the 1st year (p < 0.05). However, no differences in the incidence of other biliary complications as well as 1-, 3- and 5-year graft and patient survival were observed.
Conclusions:
UDCA administration early after DCD-OLT improves serum liver tests and decreases the incidence of biliary sludge and casts within the 1st postoperative year but does not affect overall outcome up to 5 years after OLT.
