Abstract:

BACKGROUND: Liver graft dysfunction is caused by the biliary complications after liver transplantation. Color Doppler ultrasound is widely recognized as the preferred simple inspection method of patients follow-up, which can provide reliable evidence for the diagnosis of complications after liver transplantation.
OBJECTIVE: To evaluate color Doppler ultrasound in diagnostic value of biliary complications after liver transplantation.
METHODS: The incidence of biliary complications of 126 cases with routine ultrasound examination after liver transplantation and color Doppler ultrasound results were retrospectively analyzed. The standard of diagnosis biliary complications is based on the diagnosis by magnetic resonance cholangiopancreatography (MRCP) or contrast-enhanced ultrasound or puncture and drainage or clinical treatment of diagnosis. Color Doppler ultrasound after liver transplantation was used to observe whether common bile duct and intrahepatic bile duct have bile leakage, stenosis, bile leakage, dilation, biliary sludge and stone formation.
RESULTS and CONCLUSION: A total of 33 cases with biliary complication by ultrasonic diagnosis in 126 cases, including 4 cases with bile leakage (3.2%), 11 cases with biliary stenosis (8.7%), 18 cases with biliary calculi and (or) 18 cases with biliary sludge (14.3%). It is indicated that color Doppler ultrasound has an important value in diagnosis of the biliary complications after liver transplantation, which can provide the evidence for clinical diagnosis and treatment.
