Abstract
BACKGROUND: Biliary complications (BC) are frequently observed following liver transplantation. The aim of the present retrospective study, conducted at an outpatients' tertiary care hospital, was to determine the incidence of biliary complications and risk factors associated with their development in liver transplantation (lT) patients. MATERIALS AND METHODS: The medical records were reviewed for all patients who underwent liver transplantation at the Rigshospitalet, Copenhagen, Denmark, from 2000 to 2011 and were referred to the Aarhus University Hospital for follow-up. Patients who died within 3 months of surgery or had incomplete clinical information were excluded. All data for demographic characteristics and possible risk factors for development of biliary stricture were collected. Fifty-one patients were included. RESULTS: The median age at transplantation was 40 (range=7-64) years, and 53% of patients were males. Biliary complications occurred in 18 patients (35%), the majority of whom developed strictures (12 patients, 24%). Univariate and multivariate analyses revealed that cytomegalovirus infection (p=0.008), hepatic artery obstruction (p=0.03) and hepatic artery graft abnormalities (p=0.03) were independent risk factors for the development of biliary strictures. CONCLUSION: One-third of patients presented biliary complications after liver transplantation, among which biliary strictures were the most common. Cytomegalovirus infection, hepatic artery stenosis and anatomical abnormality of the graft's hepatic artery are independent risk factors for the development of biliary stricture. Copyright
