The CBD is 5-9 cm long and is divided into three segments: supraduodenal, retroduodenal, and intrapancreatic. It lies anterior to the portal vein and to the right of the common hepatic artery, at the free border of the lesser omentum. The CBD runs behind the first part of the duodenum on top of the inferior vena cava and lies in a groove on the posterior surface of the pancreatic head. It continues down the left side of the second part of the duodenum, joining the pancreatic duct to form the ampulla of Vater, which opens into the second part of the duodenum. [39]
