Complications of the biliary tract after liver transplantation develop in 10-20% of cases. These include strictures, bile leakage, fistulas and cholangitis. Strictures of anastomoses caused by technical errors, inflammation due to bile leakage and fibrosis, and strictures not associated with anastomoses, formed above the anastomosis in the direction of the porta hepatis, caused in some cases by duct ischemia, may be observed.
