Abstract

Anatomical variations and anomalies of the biliary tract were found more often after expansion of ERCP and MRCP in clinical practice. They have been seen in up to 65% in autopsy and cholangiographic studies. The incidence of congenital anatomical variations of cystic duct was 18 - 23%. They created a number of difficulties during surgery to the biliary tree, as well as in instrumental extraction of gallstones from ampulla Vateri during the ERCP. Objective of this study was to establish the ability of MRCP to identify insertion of cystic duct (DCy), and determination of the frequency of different anatomical variations of its infusion into extrahepatic bile duct in patients with clinical signs of disease of the bile ducts and the pancreas.
