Brief Summary:

Endoscopic treatment of benign biliary strictures can be challenging. Balloon dilation and/or plastic stent placement are currently the most popular techniques. Partially covered self-expandable metallic stents have also shown to be effective but can be difficult to remove. A novel fully covered metallic stent has recently been developed.

The aim of this study was to prospectively evaluate the placement of fully covered self-expandable metallic stents (FCSEMS) in this setting.

Condition or disease Intervention/treatment Phase
Biliary Stricture Device: Placement of a FCMS in the biliary tract of the patients Not Applicable

Detailed Description:
After inclusion, an endoscopic procedure (ERCP) was performed in all patients in order to place a FCMS across the benign biliary stricture. The FCMS was left in place for 6 months and then extracted during a second ERCP procedure. An opacification was performed to assess the efficacy of stenting. Patients were followed up during one year after FCMS extraction.

Official Title: Temporary Placement of Fully Covered Self-expandable Metal Stents in Benign Biliary Strictures
Study Start Date : March 2007
Actual Primary Completion Date : March 2014
Actual Study Completion Date : March 2014

Arm Intervention/treatment
Fully covered metal stent (FCMS)
There is one arm in the study : the intervention consists on placing a device which is a fully covered metal stent in the biliary tract of all patients
Device: Placement of a FCMS in the biliary tract of the patients
During an ERCP procedure, a fully covered biliary metal stent (FCMS) is placed across a benign biliary stricture

Primary Outcome Measures :
  1. Initial success rate of temporary FCMS placement [ Time Frame: 6 months ]
    Absence of biliary stricture or as an attenuated stricture on cholangiogram after removal of FCMS

Secondary Outcome Measures :
  1. Final success [ Time Frame: 18 months ]
    Absence of biliary stricture or the presence of an attenuated stricture and normal liver function tests at the end of follow up.

  2. Stricture recurrence [ Time Frame: 18 months ]
    Both clinically and ERCP-documented recurrence of stricture after an initial success.
