Primary Outcome Measures:
  • Patency [ Time Frame: up to 32 months ]
    Number of days of stent patency: The time to stent occlusion requiring re-intervention, death, loss to follow-up, or patients alive at study end without an occlusion (>= 6 months after placement).

  • Closure or Blockage of the Stent (Occlusion) [ Time Frame: up to 32 months ]
    Biliary stents may become closed or blocked. This is also termed "Occlusion." Data for this outcome measure involve stent occlusions that required re-intervention.

  • Number of Days to Occlusion [ Time Frame: up to 32 months ]
  • Number of Deaths [ Time Frame: up to 32 months ]
  • Time to Death [ Time Frame: up to 32 months ]
    Overall Survival

Enrollment: 241
Study Start Date: September 2003
Study Completion Date: December 2006
Primary Completion Date: December 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 6 mm Zilver
6 mm Nitinol Zilver Stent
Device: 6 mm Nitinol Zilver Stent
Experimental: 10 mm Zilver
10 mm Nitinol Zilver Stent
Device: 10 mm Nitinol Zilver Stent
Active Comparator: 10 mm Wallstent
10 mm Stainless Steel Wallstent
Device: 10 mm Stainless Steel Wallstent

Detailed Description:
This research is being done to determine if the new, FDA-cleared Zilver metal biliary stent is better than the conventional stents. The new Zilver stent may permit more accurate placement, may avoid some potential complications and last longer than the conventional stents. The study will also examine to find the best diameter of stent by comparing standard 10 mm stents to 6 mm Zilver stents.
