Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Biliary anastomotic strictures (post liver transplantation) occur in 15-20 % of the cases. Biliary stenting using plastic prosthesis during a period of 1 year is the treatment of choice. Problematic in this approach is the regular change, necessary to overcome occlusion of the stent, resulting in cholestasis and/or infection. This change needs to be performed every 3 months or more frequently in patients with symptoms of stent occlusion.

The Kaffes stent (RMS) is a metallic removable stent, especially constructed for the treatment of biliary anastomotic strictures post liver transplantation. The advantage could be that this stent is less prone to occlusion with a lower change frequency (e.g. every 6 months).

No randomized, controlled trial (RCT) or data exist comparing plastic stenting versus Kaffes stenting.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Plastic stenting

Patients will be randomized towards plastic stenting.

Group Type ACTIVE_COMPARATOR

Plastic stenting

Intervention Type PROCEDURE

The patients receive plastic stenting after ortothopic liver transplantation with a choledocho-choledochal anastomosis, presenting with an anastomotic stricture. These patients will receive change of the stent every 3 months, for a total duration of 1 year.

Kaffes stenting

Patients will be randomized towards Kaffes stenting.

Group Type EXPERIMENTAL

Kaffes stenting

Intervention Type PROCEDURE

The patients receive Kaffes stenting after ortothopic liver transplantation with a choledocho-choledochal anastomosis, presenting with an anastomotic stricture. These patients will receive change of the stent every 6 months, for a total duration of 1 year.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients after orthotopic liver transplantation with a choledocho- choledochal anastomosis, presenting with an anastomotic stricture
* diagnosis established by :

* elevated liver tests
* a narrowing of the anastomosis on Magnetic resonance cholangiopancreatography (MRCP): with or without intrahepatic bile duct dilatation
* no acute or chronic rejection
* no Cytomegalovirus (CMV) infection
* no other possible causes of elevated liver tests
* confirmation of the stricture needs to be confirmed during the diagnostic endoscopic retrograde cholangiopancreatography (ERCP) procedure immediately before the therapeutic procedure.

Exclusion Criteria

* non-anastomotic strictures
* absence of informed consent
* Roux-en-Y construction
* Living related liver transplantation patients.
