title: Palliation for extrahepatic biliary obstruction by metastatic colorectal carcinoma.
abstract: OBJECTIVE
  Extrahepatic biliary obstruction due to metastatic colorectal carcinoma, though rare, can account for the occurrence of obstructive jaundice even in the presence of hepatic metastases. The present report aims at reviewing our experience with the palliative treatment of these patients.
  
  
  METHODS
  During a 5-yr period, 11 patients with obstructive jaundice had documented extrahepatic biliary obstruction secondary to metastatic colorectal carcinoma. Their clinical records were retrospectively analyzed.
  
  
  RESULTS
  Nonoperative drainage was performed in eight patients by either the endoscopic (n = 5) or percutaneous (n = 3) route. Palliation was achieved in six patients with a mean hospital stay of 24.5 days (14% of survival). Three patients died of hepatorenal failure before a drainage procedure could be performed. Blocked stent and cholangitis were noted in two patients. The mean survival was 5 months in the drainage group.
  
  
  CONCLUSIONS
  The occurrence of obstructive jaundice in patients with metastatic colorectal carcinoma deserves routine investigation to exclude extrahepatic biliary obstruction. Endoprosthesis insertion by nonoperative means should be considered for palliation.
