About this trial
This is an interventional supportive care trial for Perihilar Cholangiocarcinoma focused on measuring Endobiliary radiofrequency ablation, Stent patency
Eligibility Criteria
Inclusion Criteria:
- 18 years or older.
- Capable of providing written and oral informed consent.
- Histological or cytological proof of perihilar CCA (adenocarcinoma).
- Perihilar biliary obstruction with an indication for drainage with uSEMS.*
Advanced (no candidate for surgical resection) due to metastases, vascular or lymph node (N2) involvement on imaging or during staging laparoscopy according to multidisciplinary team (MDT).
- Only patients with pCCA are eligible however in case of reasonable doubt between intrahepatic CCA with a perihilar biliary obstruction or massforming pCCA, patients can be included.
Exclusion Criteria:
- Patients who potentially qualify for curative resection of pCCA.
- pCCA eligible for liver transplantation.
- Life-expectancy less than 3 months.
- ERCP and PTC technically not feasible.
- Uncontrolled coagulopathy (PTT >1,5x prolonged or thrombocytes below 40*10E9/L).
- Ongoing cholangitis or liver abscess. Patients are required to be off antibiotic treatment for cholangitis and/or liver abscess at least 7 days.
- Any condition that is unstable or that could jeopardize the safety of the subject and their compliance in the study.
- Patients who are pregnant or breastfeeding.

Outcomes
Primary Outcome Measures
Time to biliary obstruction
Defined as period between initial procedure and recurrence of biliary obstruction. Recurrence of biliary obstruction is defined as recurrent jaundice (conjugated bilirubin ≥ 40 umol/l (≥2.3 mg/dl)), presence of biochemical evidence of cholestasis along with dilatation of the drained bile duct(s), or endoscopic findings suggesting stent occlusion.
Secondary Outcome Measures
Quality of life expressed in quality adjusted life-years (QALYs)
EORTC QLQ-C30, BIL21 and EQ-5D questionnaires are to be filled out 4 weeks and every3 months after the intervention
Number of patients with technical success of initial ablation
Defined as completion of ablation of the malignant stenosis through which the stent will be placed using RFA for 120 seconds with 7W.
Number of patients with functional success
In case of inadequate drainage prior to the procedure (bilirubin ≥40 umol/L [≥2.3 mg/dl]), defined as 50% decrease or normalization of bilirubin level within 14 days of the procedure or relieve of symptoms in case of cholangitis. In case of sufficient drainage prior to the procedure, a persistent bilirubin level <40 umol/L (<2.3 mg/dl) after 14 days is considered functional success.
Presumed reason of recurrent biliary obstruction
Stent occlusion due to tumour ingrowth
Stent occlusion due to tumour overgrowth
Stent occlusion due to sludge with/or without stones, hemobilia, food impaction
Stent migration
Need for unscheduled re-intervention (PTC and/or ERCP) to achieve adequate biliary drainage.
Need for external drainage catheters.
Time to re-intervention.
Stent patency after repeated eRFA.
Adverse events within 30 days after the procedu
Overall survival.
Healthcare costs.
