Abstract

Abstract: The paper presents an analysis of the data of ultrasound, CT, MRCP and
intraoperative cholangiography in patients with bile duct cyst. Echographic data are
presented in 86 patients, CT in 61, MRCP in 8 and intraoperative cholangiography in 73
patients with this pathology. Ultrasound is a highly sensitive and informative screening
method for the diagnosis of choledochal cysts in children. To increase the specificity of
ultrasound with cysts of the common bile duct, a dynamic study of the contractility of the
biliary system after taking a "choleretic breakfast" is proposed. Currently, in the diagnosis
of pathology of the biliary tract, CT of the abdominal cavity and MRCP are effective noninvasive
methods, alternative to invasive ERCP. It has been established that the final
verification of the form of bile duct cysts, abnormal fusion of the pancreatic duct into the
cyst cavity is determined using MRCP and intraoperative cholangiography, which allows
you to choose the optimal method of surgical treatment.
