A Randomized Trial Comparing the Uncovered to the Covered Wallstent in the Palliation of Malignant Bile Duct Strictures
- greater than 18 years of age.
- Malignant bile duct stricture.
- Increased bilirubin.
- Duct stricture is > 1 cm distal to the biliary hilum (bifurcation of the common
hepatic duct into the right and left hepatic ducts).
- Not an operative candidate.
- Unable to obtain consent.
- Unable to tolerate procedure.
- Suspected benign bile duct stricture.
- Candidate for potentially curative surgical intervention.
- Previous metallic biliary stent.
- Previous bile duct surgery.
Type of Study:
Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Supportive Care
To compare the stent patency time in the uncovered and covered Wallstent groups in subjects with malignant bile duct strictures.
