Palliative surgical bypass versus percutaneous transhepatic biliary drainage on unresectable hilar cholangiocarcinoma.

Abstract

OBJECTIVE:

To compare the survival probability of unresectable hilar cholangiocarcinoma patients who have been managed by palliative surgical bypass versus percutaneous transhepatic biliary drainage (PTBD).

MATERIAL AND METHOD:

A historical (retrospective) cohort study was performed by retrospective and prospective data collection. From January 1, 2000 to December 31, 2002, all unresectable hilar cholangiocarcinoma patients who received only one type of palliative surgical bypass or PTBD in Srinagarind Hospital, Khon Kaen University were included in the present study. The patients were followed until December 31, 2004. Survival analysis was completed for all of the patients. STATISTIC ANALYSIS: Survival analysis was analyzed with the Kaplan-Meier method, Cox regression analysis, and Log-rank test. A p-value of less than 0.05 was considered significant.

RESULTS:

During the study period, 83 patients were included. Palliative surgical bypass was performed in 42 patients and PTBD was performed in 41 patients. Demographic data, peri-operative complication rate, and late complication rate were comparable. The median survival time of the palliative surgical bypass group was 160 days,(95% CI: 85.33, 234.67) and 82 days (95% CI: 29.76, 134.24)for PTBD group. Comparing survival experience by Log-rank test gave statistical significant diference (p = 0.0276). Hazard ratio was 0.599 (p = 0.03)

CONCLUSION:

Survival rate of the palliative surgical bypass group was higher than the PTBD group. The survival rate of both groups was comparable to previous reports.
