Clinical evaluation of a low junction of the cystic duct.
The point of the junction of the cystic duct with the common hepatic duct was studied by means of various preoperative and intraoperative cholangiographic procedures and by gross intraoperative examinations in 468 surgical patients with biliary diseases. The cystic duct entered the hepatic duct at a very low position and was consequently long in 39 patients. The clinical significance of this abnormally low junction of the cystic duct was studied in comparison with 358 patients with gallstones with a normal cystic duct-hepatic duct junction. In the low-junction group with a short common bile duct several complications, including gallstone pancreatitis (7 patients), the Mirizzi syndrome (7), confluence stones (2), gallbladder cancer (3), and congenital dilation of the cystic duct (1), were demonstrated preoperatively. The anomalous junction of the cystic duct with the common bile duct may cause stagnation of bile and/or reflux of pancreatic juice into the bile duct, producing a choledochopancreatic ductal junction and posing difficulties at surgery.
