A

Accessory duct empties into the right hepatic duct in transverse fissure (porta hepatis). Distance between the accessory duct and junction of the cystic duct with the common hepatic duct is 3.5 cm.

B

Essentially as in A. The distance between the cystic duct and accessory duct is 2.1 cm.

C

Cystic duct empties into the accessory duct close to its junction with the common hepatic duct. Accessory duct approximates the diameter of the common hepatic duct. Distance between accessory duct junction with common hepatic duct and junction of right and left hepatic ducts is 2.7 cm.

D

Characteristics essentially the same as C. Distance between junction of right and left hepatic ducts and junction of accessory duct with common hepatic duct is 1.2 cm.

E, I, J

These are essentially the same in that the accessory duct empties into the common hepatic duct midway between junction of right and left hepatic ducts and junction of the cystic duct with the common hepatic duct. Length of the common hepatic duct in E and I is 3 cm, and in J is 2.2 cm.

F

Accessory hepatic duct empties into the common hepatic duct simultaneously with the cystic duct. Distance of accessory duct junction from beginning of the common hepatic duct is 3.5 cm. Diameters of the accessory and common hepatic ducts are the same.

G

Cystic duct empties into the right hepatic duct 1 cm from hilum of liver. Junction of right and left hepatic ducts is approximately 2 cm from hilum of liver. Accessory hepatic duct empties into the common bile duct 2.5 cm from junction of right and left hepatic ducts and 3.5 cm from the cystic duct junction. Diameter of accessory duct is the same as that of the common bile duct.

H

Accessory duct empties into the common hepatic duct. Distance between the accessory duct and cystic duct junction with the common hepatic ducts is 2.2 cm. Accessory duct lies under the surface of the liver.
