Postoperative biliary adverse events following orthotopic liver transplantation: Assessment with magnetic resonance cholangiography

摘要: Biliary adverse events following orthotopic liver transplantation (OLT) are relatively common and continue to be serious causes of morbidity, mortality, transplant dysfunction or failure. The development these is heavily influenced by the type anastomosis during surgery. low specificity clinical biologic findings makes diagnosis challenging. Moreover, direct cholangiographic procedures such as endoscopic retrograde cholangiopancreatography percutaneous transhepatic cholangiography present an inadmissible rate utilized in clinically suspected patients. Magnetic resonance (MR) maging with MR crucial assessing abnormalities biliary system after surgery, including transplant. a safe, rapid, non-invasive, effective diagnostic procedure for evaluation transplantation, since it plays increasingly important role management events. On basis recent systematic review literature summary estimates sensitivity OLT were 0.95 0.92, respectively. It can provide non-invasive method imaging surgical reconstruction anastomoses well anastomotic non-anastomotic strictures, lithiasis sphincter Oddi recipients. Nevertheless, conventional T2-weighted implemented T1-weighted contrast-enhanced using hepatobiliary contrast agents (in particular Gd-EOB-DTPA) order improve accuracy events’ detection bile leakage especially selected patients biliary-enteric anastomosis.
