title: [The causes of death in patients with malignant biliary obstruction treated by metallic stent and/or biliary drainage].
abstract: OBJECTIVE
  To analyze the causes of death in patients with malignant bile duct obstruction treated by metallic stent endoprosthesis and biliary drainage.
  
  
  METHODS
  One hundred and seven patients with malignant bile duct obstruction were so treated. Of the 107 patients, 12 (11.2%) died within 30 days after operation. The bile duct obstruction in the 12 cases was due to primary hepatic cancer(n = 4), metastasis of lymph nodes in hepatic hilus(n = 3) and bile duct cancer(n = 5).
  
  
  RESULTS
  Five patients died of biliary infections, 4 patients died of hepatic coma, and 2 patients died of cancerous cachexia and 1 patient died of biliary tract hemorrhage.
  
  
  CONCLUSIONS
  The major causes of postoperative death of patients with biliary obstruction treated by metallic stent to support bile duct are biliary infection and hepatic encephalopathy.
