title: One-step insertion of an expandable metallic stent for unresectable common bile duct carcinoma.
abstract: BACKGROUND
  This report describes a one-step insertion of an expandable metallic stent to treat obstructive jaundice due to unresectable common bile duct carcinoma.
  
  
  METHODS
  A percutaneous transhepatic cholangiogram is obtained, and the bile duct obstruction is negotiated with a guide wire. After advancing the catheter into the duodenum, contrast material is injected to measure the length of the stenosis. After an expandable metallic stent is positioned, an external biliary drainage catheter is left in place to provide temporary drainage. The catheter is removed after stent patency is confirmed after 3 days.
  
  
  CONCLUSIONS
  One-step insertion of an expandable metallic stent for biliary obstruction is a useful method that shortens hospitalization. Once it has been decided to use stent palliation, the stent should be inserted without undue delay to maximize symptomatic relief and cost benefits.
