Detaljeret beskrivelse
Research hypothesis
The use of biodegradable stents leads to remodelling of high grade strictures in patients with PSC with fewer interventions in comparison to balloon dilation alone with a comparable risk profile to current therapy.
Primary endpoint
Technical success and safety of biodegradable stent placement at ERC
Secondary endpoints
- Cumulative recurrence -free rate of primary high grade strictures within 12 months
- Change in symptoms as assessed by the Amsterdam cholestatic complaints score (ACCS)
- Clinical success is defined by improvement in liver function tests (LFT) by 20% at week 2 and week 12.
- Improvement in quality fo life as assessed by the Short form-36 (SF-36).
- Mortality, morbidity, local complications, stricture recurrence, decompensation of liver disease, liver transplantation over 12 months.
