Primary Outcome Measures:
  • Obstruction of 1st C-SEMS or presence of jaundice at death without stent exchange [ Time Frame: one year ]

Secondary Outcome Measures:
  • Death of patients [ Time Frame: one year ]

Enrollment: 120
Study Start Date: January 2010
Study Completion Date: September 2012
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Group A: C-SEMS, inserted above SO
-In group A, SO should be preserved without sphincterotomy, but small infundibulotomy with needle knife can be accepted for cannulation.
Device: PTFE Covered ComVi [full covered] Biliary Stent
The stent is made of Nitinol wire. It is a flexible, fine mesh tubular prosthesis and it has 10 radiopaque markers; 4 in each end and 2 in the center.
Other Name: PTFE Covered ComVi [full covered] Biliary Stent, Taewoong Medical, Korea
Active Comparator: Group B: C-SEMS, inserted across SO
-In group B, small sphincterotomy (50% incision) will be done after biliary cannulation.
Device: PTFE Covered ComVi [full covered] Biliary Stent
The stent is made of Nitinol wire. It is a flexible, fine mesh tubular prosthesis and it has 10 radiopaque markers; 4 in each end and 2 in the center.
