The name of the treatment contains 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® allows for differentiating the procedure with ECHOLASER® (micro-invasiveness and multi-fibre approach in a single system) from the other thermal ablation techniques.
When PBLite® is used?
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 of those who, due to critical medical conditions, are not able to undergo surgery.
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 causes the heating of 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 complete ablation of the lesion and subsequent absence of post-treatment local relapses and a net increase in the long-term survival probabilities (5 years).
- a complete ablation with a sufficient safety margin
- “in situ” thermal destruction
- a 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, a-traumatic needles for liver organ
- possibility of treating patients with pace-makers (excellent electromagnetic compatibility)
- absence of general anesthesia
- short duration of the treatment (few minutes)
- rapid recovery times
- no or insignificant post-treatment pain
- brief hospitalization
- bridging therapy for organ transplants
