They have now been replaced in diagnosis by MR-cholangiography. Due to all of the above considerations it is recommended that each case be evaluated individually, and that surgery be used if an R0 resection can be achieved in the absence of distant metastasis or peritoneal involvement. The group without preoperative drainage non-PBD was composed of patients, and the group with biliary drainage PBD contained patients.

Resectability is further assessed at operation by careful exploration for peritoneal implants, hepatic metastasis and regional lymph node involvement. With the improved diagnostic tests and histopathological knowledge, in the future we may be better able to define whether they are 2 distinct entities or if they are clinically and biologically the same.

This classification aims to predict the resectability of tumours, taking 3 local extension factors into account.

However, a tissue diagnosis is important to differentiate a stricture due to primary sclerosing cholangitis from hilar cholangiocarcinoma in patients who might otherwise be candidates for liver transplantation. Surg Gynecol Obstet ; Primary peritoneal carcinoma Peritoneal mesothelioma Desmoplastic small round cell tumor.

The standard operative approach at the Johns Hopkins Hospital for bifurcation tumors is limited resection to the hepatic duct bifurcation with reconstruction as a bilateral hepaticojejunostomy with the routine use of transhepatic silastic stents.
