 We have used selective cholangiography via percutaneous transhepatic biliary drainage (PTBD) and performed percutaneous transhepatic cholangioscopy (PTCS) to achieve accurate preoperative knowledge of the extent of cancer spread into the bile duct. Selective cholangiography demonstrates biliary stiffness and narrowing which are characteristic findings of cancer involvement of the bile duct wall. High-quality cholangiograms achieved with PTBD in various positions are essential for obtaining precise informations about cancer extension. In superficial spreading carcinoma of the biliary tract, PTCS plays an important role in providing precise preoperative knowledge of the cancer extension into each segmental bile duct. Cholangiograms of the biliary branches of the caudate lobe (B1) were also compared with the pathologic findings. The groups without stenosis, with long segmental stenosis, and poor images could be diagnosed accurately by tube cholangiography and PTCS. On the other hand, in a group with short segmental stenosis it was difficult to diagnose cancer invasion to the confluence of Bl. Positive invasion existed only in one-third of the group but negative extension was present in two-thirds of the group.
