Core Tip

Core tip: Biliary complications represent a leading cause of morbidity and mortality in liver transplant recipients. To date, endoscopic retrograde cholangiopancreatography still remains the gold standard for diagnosing and treating such complications. The present study examined the benefit of complementary single-operator cholangioscopy. Our results are encouraging and demonstrate strong evidence for a diagnostic and therapeutic advantage of additional cholangioscopy for management of biliary disorders following liver transplantation.
