Study Overview

Comparing Covered Self-expandable Metallic Stent (SEMS) Above/Across the Sphincter of Oddi

The purpose of this prospective, randomized multicenter study is to determine whether there is any difference in stent patency of covered metallic stents in terms of stent positioning, above and across the sphincter of Oddi, in malignant bile duct obstruction.

Study Plan

This section provides details of the study plan, including how the study is designed and what the study is measuring.

Design Details

Primary Purpose:
Supportive Care


Allocation:
Randomized


Interventional Model:
Single Group


Masking:
Single


Arms and Interventions

Participant Group/ArmIntervention/Treatment
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.
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.
Primary Outcome MeasuresMeasure DescriptionTime Frame
