Outcome Measures

Primary Outcomes (2)

  • Stent patency

    Analysis of metal stent patency since insertion in both study arms (measured in months, Kaplan-Meier estimate).

    up to month 36 or death of the patient

  • Overall survival

    Analysis of overall survival since the diagnosis, initial drainage, and metal stent insertion in both study arms (measured in months, Kaplan-Meier estimate).

    up to month 36 or death of the patient

Secondary Outcomes (1)

  • Complications of endoluminal RFA of biliary tract

    up to day 30

Study Arms (2)

Experimental arm - endoluminal RFA

EXPERIMENTAL

standard treatment protocol for malignant biliary stenosis + endoluminal RFA prior metal stent insertion

Device: Habib™ EndoHPB; Boston Scientific, US; former EMcision Ltd., UK

Control arm

NO INTERVENTION

standard treatment protocol for malignant biliary stenosis which includes metal stent insertion

Interventions

Randomised patients in selected arm received endoluminal RFA by 8F catheter (Habib™ EndoHPB; Boston Scientific, US; former EMcision Ltd., UK) before stenting procedure. Repeated ablations were processed through stenotic areas of bile ducts (10W, 90-120s, Rita 1500, Angiodynamics Ltd), all drained biliary tracts were used for introducing catheter and performance of ablation. Ablation procedure was followed with uncovered self-expandable metal stent insertion.
