What is percutaneous tumour ablation?
Liver tumours are destroyed by heat (radiofrequency ablation, microwave) or, for lesions close to the bile ducts or pancreatic duct, by electrical pulses (irreversible electroporation — IRE/NanoKnife), via percutaneous image-guided access without surgery.
Why choose this technique?
- It provides targeted local treatment of primary or secondary liver lesions
- It preserves as much healthy liver as possible
- An alternative to surgery with similar efficacy, fewer complications and a shorter hospital stay for tumours smaller than 3 cm
- It is also possible for larger lesions while awaiting surgery or liver transplantation
Who is this method for?
All indications are determined at a dedicated multidisciplinary team meeting (hepatology, digestive oncology, etc.).
- Single or multiple liver tumours smaller than 3 cm (sometimes possible for larger lesions)
- Hepatocellular carcinoma and liver metastases
How does it work?
Short hospital stay (usually 1 to 3 days)
Under general anaesthesia
Percutaneous image-guided puncture (ultrasound, CT scan, cone-beam CT ± fusion of several modalities)
Protective measures are put in place if needed (carbodissection or hydrodissection)
Destruction of the tumour using the method determined by its location and the patient's history
Short post-procedure monitoring
What is the recovery like?
- Moderate pain over the abdominal wall is possible
- Possible but rare complications: haematoma, numbness of the skin near the treated area, exceptional bowel perforation
- Short hospital stay
- Radiological follow-up at 1 and 3 months, then every 3 months by imaging
What to prepare before the consultation
If you are referred by a doctor in our centre, we usually have all the necessary information.
- A recent CT or MRI scan
- Liver work-up
- A summary letter from your doctor
🏥 Rapid diagnosis of liver tumours: a dedicated pathway
Cochin Hospital has a rapid diagnostic pathway for liver tumours, in collaboration with the Hepatology Department of Professor Romain Coriat. If you have a liver abnormality detected on imaging, rapid, coordinated management is possible, including a complete diagnostic work-up, discussion at a hepatology MDT meeting and referral to the most appropriate treatment (surgery, interventional radiology, chemotherapy).
