Until December 1984 all 100 ERC that met the following three conditions were studied which at Yachio Hospital. 1. The first cholangiogram. 2. Without obstructive jaundice. 3. No existence of lesion at the hepatic hilum.
Bile duct of the caudate lobe were classified into 4 separate types：1) Ducts from the cranialis of the right caudate lobe which pass via the inferior vena cava to the hepatic hilum named B1r, were confirmed in 32. 2) Ducts from the cranialis of the left caudate lobe to the hepatic hilum named B1ls, were confirmed in 19. 3) Ducts from the left lateral part of the left caudate lobe to the hepatic hilum named B1li were confirmed in 37. 4) Ducts from the caudate process to the hepatic hilum named B1c, were confirmed in 5. One or more of the above bile ducts were confirmed in 53 cases. All four of the above were confirmed in only 2 cases out of 53 cases. Three were confirmed in 7 out of 53 cases, two were confirmed in 20 cases out of 53 cases and one was confirmed in 24 out of 53 cases.
Studies for the bile duct of the caudate lobe have been conducted anatomically, but there has been no research by clinical examination. It has been believed that it is impossible to confirm bile duct in the caudate lobe by cholangiogram, but this study suggests that biliary in the caudate lobe can be demonstrated by ERC.
