Long-term outcome in patients with advanced hilar bile duct tumors undergoing palliative endoscopic or percutaneous
1Department of Internal Medicine II, Technical University of Munich, Rechts der Isar Hospital, Germany.
Objective:
Advanced tumors of the hepatic duct bifurcation (Klatskin tumors) present problems to the endoscopist in deciding which procedure to use for palliative treatment of the resulting cholestasis--endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic biliary drainage (PTBD), or both. There are technical difficulties with all forms of treatment for stenoses in the hilar region and intrahepatic bile ducts, and there are as yet no clear data on which type of drainage is feasible or preferable.
Subjects:
59 consecutive patients (30 men, 29 women; mean age 71 years) underwent palliative treatment for malignant hilar bile duct tumors of Bismuth stages II-IV during a three-year period (1992-94).
Method:
A retrospective analysis was carried out, and long-term follow-up data were obtained from telephone interviews with the patients, relatives, or referring physicians.
Results:
The 59 patients were treated using ERCP (n = 20) or PTBD (n = 39). Three died within 30 days, and six were lost to follow-up. Clinically adequate drainage was achieved in 78% (n = 46) of the total patient group. Patient survival was a median of six months (range 0.5-38), and was slightly longer when the primary drainage procedure was successful (7.5 months). Initial complications occurred in 11% after ERCP and in 33% after PTBD, with a 30-day mortality of 5%. After the initial intervention, five patients who received ERCP treatment had to be switched to PTBD during the longer-term course. Three of these five patients died within 30 days of the PTBD insertion.
Conclusions:
Palliative treatment in patients with advanced Klatskin tumors is still suboptimal, even when combined endoscopic and percutaneous techniques are used in the same institution, allowing treatment to be tailored to the individual patient's needs. There is therefore a need for improvements in existing forms of treatment, as well as for the development of new forms of treatment.
