Clinical outcome after biliary drainage for metastatic colorectal cancer: Survival analysis and prognostic factors.

Introduction: Biliary obstruction secondary to colorectal cancer liver metastases is associated with a poor prognosis especially when chemotherapy cannot be re-started. The aim of this study was to determine the survival after biliary drainage and the associated prognostic factors.

Methods: Patients from two French centers were included retrospectively after first biliary endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography drainage for biliary obstruction secondary to liver metastases of colorectal cancer, occurring during chemotherapy.
