Outcome Measures

Primary Outcomes (2)

  • Technical success of ERCP procedure

    Ability to correctly apply radiofrequency ablation and place stents in all the biliary ducts accessed on ERCP

    2 months

  • Tumor response

    To evaluate the efficacy of radiofrequency ablation in local disease control by assessing tumor response according to RECIST criteria at 6 months follow-up

    6 months

Secondary Outcomes (3)

  • Rate of procedure-related adverse events

    12 months

  • Overall survival

    12 months

  • Tumor microenvironment alterations

    2 months

Study Arms (2)

Endoscopic Drainage Arm

ACTIVE COMPARATOR

Patients randomized to this arm will undergo biliary stenting only

Procedure: Endoscopic biliary stenting

COMBO-RFA Arm

EXPERIMENTAL

Patients randomized to this arm will undergo same-session endoluminal radiofrequency ablation followed by biliary stenting

Procedure: Endoluminal radiofrequency ablationProcedure: Endoscopic biliary stenting

Interventions

Endoluminal radiofrequency ablationPROCEDURE

Endoluminal Radiofrequency ablation (RFA) of the entire stricture length will be performed using the Habib probe. A current of 7W will be delivered for 90s intervals at a time. If multiple ablation sessions are needed in order to ablate the entire stricture lenght, there will be an overlap of ablated areas in order to ensure proper stricture treatment. Dilation of the stricture prior to RFA delivery will be performed if required. After RFA treatment, biliary drainage of all hepatic territories will be ensured.

COMBO-RFA Arm
Endoscopic biliary stentingPROCEDURE

Endoscopic biliary stenting will be performed via ERCP using multiple plastic stents, in order to ensure propper drainage of all accessed hepatic territories.
