Progress in the treatment of biliary obstruction after liver transplantation

Biliary obstruction is one of the most important biliary complications after liver transplantation, with high incidence and high mortality. Prevention and timely treatment is very important for long-term survival of patients. Magnetic resonance cholangiography (MRCP), as a reliable and non-invasive tool for detecting biliary complications, has been widely accepted. Endoscopic retrograde cholangiopancreatography (ERCP) is the first choice for non-operative biliary obstruction after liver transplantation. The patients with invalid endoscopic treatment or severe obstruction symptom should have surgical therapy or liver re-transplantation.
