    Abstract:
    BACKGROUND: Biliary complications are the second leading cause of morbidity and mortality in orthotopic liver transplant (OLT) recipients. Endoscopic retrograde cholangiography (ERC) is considered the diagnostic criterion standard for post-orthotopic liver transplantation biliary obstruction, but incurs significant risks. OBJECTIVE: To determine the diagnostic accuracy of MRCP for biliary obstruction in OLT patients. DESIGN: A systematic literature search identified studies primarily examining the utility of MRCP in detecting post-orthotopic liver transplantation biliary obstruction. A meta-analysis was then performed according to the Quality of Reporting Meta-Analyses statement. SETTING: Meta-analysis of 9 studies originally performed at major transplantation centers. PATIENTS: A total of 382 OLT patients with clinical suspicion of biliary obstruction. INTERVENTIONS: MRCP and ERCP or clinical follow-up. MAIN OUTCOME MEASUREMENTS: Sensitivity and specificity of MRCP for diagnosis of biliary obstruction. RESULTS: The composite sensitivity and specificity were 0.96 (95% CI, 0.92-0.98) and 0.94 (95% CI, 0.90-0.97), respectively. The positive and negative likelihood ratios were 17 (95% CI, 9.4-29.6) and 0.04 (95% CI, 0.02-0.08), respectively. LIMITATIONS: All but 1 included study had significant design flaws that may have falsely increased the reported diagnostic accuracy. CONCLUSIONS: The high sensitivity and specificity demonstrated in this meta-analysis suggest that MRCP is a promising test for diagnosing biliary obstruction in patients who have undergone liver transplantation. However, given the significant design flaws in most of the component studies, additional high-quality data are necessary before unequivocally recommending MRCP in this setting.
