The cure rate of bile duct stenosis 2 years after liver transplantation depends on the cause of bile duct stenosis and the degree of stenosis. If it is an anastomotic stricture, it can be relieved by stenting under ERCP; if it is caused by ischemic cholangitis, it can be relieved in about 40% of the patients; if it is a complete stricture, it may be in about 10%, and if it is a partial stricture, it may be in about 50%. The cure rate of biliary stenosis after liver transplantation mainly depends on the cause of the stenosis. If it is anastomotic stenosis, it can be relieved by stent implantation under ERCP; if it is caused by ischemic cholangitis, it can be relieved in about 40% of the patients, and some of the patients may even need to undergo liver transplantation again in order to cure the biliary stenosis. The cure rate of biliary strictures after liver transplantation also depends on the degree of stricture. If the stenosis is complete, it may lead to cirrhosis of the transplanted liver, hepatic coma and upper gastrointestinal bleeding in the later stage, and the cure rate is low, usually around 10%. If there is partial narrowing of the biliary tract after liver transplantation, it can be treated by endoscopic retrograde cholangiopancreatography or placing an endobiliary support tube, and its success rate can be more than 50%. When biliary tract stenosis occurs after liver transplantation, it is recommended to go to the Hepatobiliary Surgery Department of regular hospitals in time for treatment under the guidance of doctors.
