Brief Summary:
Patients with malignant bile duct stenosis have poor prognosis and most of the patients are not good candidate for surgery at the time of diagnosis. Placement of the stent is the palliative care for these patients. However over 50% of the stents get blocked within 6-8 months. Use of the radiofrequency ablation before the stent placement may improve stent patency. Heat will be applied to the bile duct in order to open the blockage and prevent the re-growth of tissue into the stent. The investigators are looking to see how safe and feasible RFA (Radiofrequency ablation) catheter is in patient with malignant bile duct stenosis.

Condition or disease Intervention/treatment Phase
Obstruction of Biliary Tree Biliary Tract Cancer Biliary Tract Neoplasms Device: Radiofrequency ablation catheter (Habib EndoHBP) Not Applicable

Detailed Description:
As part of medical care subjects will be undergoing an endoscopic procedure (ERCP) in order to evaluate and stent a bile duct blockage. During the ECRP and just prior to the stent placement subjects will undergo the placement of a radiofrequency ablation catheter into the bile duct blockage. Heat will be applied to the bile duct in order to open the blockage and prevent the re-growth of tissue into the stent; after the radiofrequency ablation, stent will be placed. Three days after the procedure subjects will receive a phone call from the research coordinator to check any adverse or unwanted effects of the treatment. The study procedure (radiofrequency ablation) takes place over 10 minutes during ERCP. The subjects will undergo routine follow up for their medical problems. No follow up visits are required as part of the study.

Arm Intervention/treatment
Experimental: Treatment
Radiofrequency ablation catheter
Device: Radiofrequency ablation catheter (Habib EndoHBP)
Catheter placement into bile duct
Other Name: Habib EndoHBP

Primary Outcome Measures :
  1. Safety: Number of Bile Leak After RFA Procedure [ Time Frame: 2 years ]
    Determination of safety will be measured by the presence of a bile leak( bile leak will be defined by contrast cholangiography)

Secondary Outcome Measures :
  1. Feasibility: Ease of the Radiofrequency Ablation Catheter Placement [ Time Frame: 2 years ]
    Determine the feasibility of radiofrequency ablation catheter placement across malignant strictures with using a subjective scale, 0 is being impossible to place the catheter and 10 is being very easy to place the catheter.

  2. Effectiveness: Change From Baseline in Bile Duct Diameter. [ Time Frame: 2 years ]
    Effectiveness will be determined by change in stricture diameter (increase or decrease) after RFA procedure. This will be measure as percentage change in improvement of the stricture.
