Background: Surgical resection is the only possibility of long term survival in patients with Klatskin tumours. However, surgical resection is a challenging problem and hepatic resection is often necessary.
Objective: The aim of our study was to assess the need for biliary drainage, resection rate and outcome of hilar cholangiocarcinoma in a single tertiary referral centre.
Patients and methods: From 2005 to 2008, 26 patients with Klatskin tumours were identified and assessed prospectively with multidetector CT and MR cholangiography in special cases. Seven patients (27%) were deemed to be unresectable in pre-operative staging. A total of 19 surgical procedures were performed, 8 left hepatectomies, 5 right hepatectomies and 6 resections exclusively of the biliary tree.
Results: Resection rate was 73%, transfusion rate 53% and preoperative biliary drainage was performed only in 7 cases (37%). Major complications occurred in 11 (58%), including two post-operative deaths (10%). There were no differences in the epidemiological data, when we separately analysed the outcomes of the 9 patients with bilirubin<15 mg/dL and the 10 patients with bilirubin>15 mg/dL. Biliary drainage was required in 6 (67%) patients in the group with low bilirubin levels vs. 1(10%) in the other group (P=0.02). The mean bilirubin level in the jaundiced group was 22.1+/-3.9 vs. 4.7+/-4.3 (P<0.001) in the other group. There were no differences in the postoperative outcome between both groups.
Conclusion: Resection and survival rates have increased recently but still carries the risk of significant morbidity and mortality. Major hepatectomies in selected patients without percutaneous biliary drainage are safe.
