ClinicalTrials.gov Identifier:
NCT01393067
First received: July 12, 2011
Last updated: October 25, 2013
Last verified: October 2013
  Purpose

Stenosis at the bilio-biliary anastomosis occurs in up to 30% of patients after orthotopic liver transplantation. This study compares endoscopic treatment with implantation of multiple plastic endoprostheses vs. use of a removable, covered self-expandable metal stent (cSEMS).


Condition Intervention
Stenosis of the Bilio-biliary Anastomosis After Orthotopic Liver Transplantation
Device: Non-expandable plastic stent (plastic endoprosthesis)
Device: Covered self-expandable metal stent (cSEMS)

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Comparison of Use of Covered, Self-expandable Metal Stents (cSEMS) and Non-expandable Plastic Stents (NEPS) in Temporary Endoscopic Treatment of Stenosis of the Bilio-biliary Anastomosis After Liver Transplantation

Primary Outcome Measures:
  • Number of interventions (ERCP) to attain resolution of stenosis [ Time Frame: up to one year ] [ Designated as safety issue: No ]
    Number of interventions (ERC) in study group cSEMS is compared to number of interventions (ERC) in study group NEPS


Secondary Outcome Measures:
  • Occurence and severity of complications related to the endoscopic procedures [ Time Frame: up to 2 months after ERCP ] [ Designated as safety issue: Yes ]
