Roux-en-Y reconstruction, however, is preferentially used in patients transplanted for primary sclerosing cholangitis (PSC), and the disease itself is also associated with a higher incidence of NAS. The aim of this study was to determine whether Roux-en-Y reconstruction is really an independent risk factor for NAS. A series of 486 consecutive adult liver transplants were studied. Biliary reconstruction in patients transplanted for PSC was either by Roux-en-Y choledochojejunostomy or by duct-to-duct anastomosis, depending on the quality of the recipient's extrahepatic bile duct. Univariate and multivariate statistical analyses were used to identify risk factors for the development of NAS. The overall incidence of NAS was 16.5% (80\/486). In univariate analyses, the following variables were significantly associated with NAS: PSC as the indication for transplantation, type of biliary reconstruction (Roux-en-Y versus duct-to-duct), and postoperative cytomegalovirus infection. After multivariate logistic regression analysis, PSC as the indication for transplantation (odds ratio, 2.813; 95% confidence interval, 1.624-4.875;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001) and postoperative cytomegalovirus infection (odds ratio, 2.098; 95% confidence interval, 1.266-3.477;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.004) remained as independent risk factors for NAS. Biliary reconstruction using Roux-en-Y choledochojejunostomy was not identified as an independent risk factor for NAS. In conclusion, the association between Roux-en-Y choledochojejunostomy and NAS observed in previous studies can be explained by the more frequent use of Roux-en-Y reconstruction in patients with PSC. Roux-en-Y reconstruction itself is not an independent risk factor for NAS.
