Applications
Why abandon the idea of a micro-invasive approach
in case of lesions in positions at risk?

PBLite is the ECHOLASER Thermal Ablation treatment for malignant abdominal tumours, in particular primary and secondary liver cancers.

The name of the treatment encapsulates in a single word the application area (the liver, “PB” is the abbreviation of Prometheus bound, the titan who in Greek mythology was condemned to be bound to the rocks of the Caucasus while an eagle pecked at his liver each day) and “Lite”, which on one hand refers to the lightweight and micro-invasiveness of the treatment, and on the other, the therapeutic source (Light, therefore Laser).

The name PBLite marks the difference of the procedure performed with ECHOLASER (micro-invasiveness and multi-fibre approach in a single system) from the other thermal ablation techniques.

Suitability

PBLite is indicated in the treatment of primitive and secondary liver cancer in the form of focal lesions. PBLite is also a safe and effective treatment for those who, due to critical medical conditions, are unable to undergo surgery.

What is it?

PBLite consists of the percutaneous insertion of optical fibres (from 1 to 4 depending on the size of the tumour), and the delivery of laser energy for several minutes, which heats the tissues until they are completely destroyed with a sufficient safety margin. The positioning of the applicators, monitoring of the treatment and verification of the effective coagulation area are all carried out under ultrasound guidance. In order to facilitate the insertion manoeuvre, the system has dedicated multi-applicator Guiding Systems for ultrasound probes designed for the anatomical area of the liver with relative Biopsy Software that displays the guidelines on the screen. As these are malignant tumours, the objective of the treatment is a complete ablation of the lesion and subsequent absence of local post-treatment relapses and a net increase in the long-term survival probability (5 years).

With just one PBLite session it is possible to treat liver lesions with a very wide size range and diameters of up to 5 cm thanks to the versatility provided by the multi-fibre approach. The localized thermal effect of PBLite makes it the gold standard for liver lesions close to structures at risk.

3./4. CA541 Esaote probe with dedicated multi-fibre Guiding System

Advantages

complete ablation with a sufficient safety margin
“in situ” thermal destruction
preservation of the healthy tissue and the organ function
highly predictable and repeatable coagulation volume as required for the safety margin
localized thermal effect in the target volume only, which makes the treatment possible close to sites at risk
use of fine, non-traumatic needles for liver organ
possibility of treating patients with pace-makers (excellent electromagnetic compatibility)
no general anesthesia
short duration of the treatment (few minutes)
rapid recovery
no or insignificant post-treatment pain
brief hospitalization
bridging therapy for organ transplants

 

 

 

 

Clinical Case no.1: primary liver tumour close to vascular structures

A patient with partially exophytic liver cancer (white arrow in the Figure), located between a branch of the portal vein and the vena cava, underwent EchoLaser Thermal Ablation using four fibres, two positioned in the upper section of the portal vein and two in the lower section. The lesion which was particularly difficult to treat due to the surrounding veins, was completely ablated without any alterations to the surrounding vascular structures.

Clinical Case no.2: secondary colorectal cancer close to the heart

A patient with an 8-mm metastasis of the liver in segment I extremely close to the pericardium, was subjected to the EchoLaser Thermal Ablation. The lesion was completely ablated without any complications involving critical neighbouring structures such as pericardial effusion.
