Pilot Study on the Evaluation of Irreversible Electroporation Technique in Infiltrating Perihilar Cholangiocarcinoma

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to evaluate the feasibility of irreversible electroporation in the treatment of locally advanced cholangiocarcinoma. This technique would allow to treat the unresectable part of the tumor to make it more accessible for a secondary surgery.

Design Details

Primary Purpose: Treatment
Intervention Model: Single Group Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Electrodes<br>Electrodes | Procedure: Irreversible electroporation<br>* Device: NanoKnife The aim of the treatment is to surround the tumour with two to six needles and to deliver a very high voltage current (3000 volts in 70 to 80 microseconds pulses) by a generator synchronized with an electrocardiogram.<br>|
