Area of Science:

Hepatobiliary surgery
Minimally invasive surgical techniques
Radiofrequency applications in oncology

Background:

Radiofrequency ablation (RF) is an emerging therapy for hepatic tumors.
Existing RF devices for hepatectomy were adapted from those for unresectable tumors.
A new bipolar radiofrequency device specifically for liver resection is introduced.

Purpose of the Study:

To describe a novel technique for liver resection using a bipolar radiofrequency device.
To evaluate the safety and feasibility of this new technique.
To assess its impact on blood loss and liver parenchyma preservation.

Main Methods:

Ten patients underwent liver resection utilizing a bipolar radiofrequency device.
A minimal zone of desiccation was created around the tumor using opposing electrodes and minimal energy.

The coagulated plane was subsequently divided with a scalpel.

Main Results:

Liver parenchyma division resulted in minimal blood loss.
No patients required intensive care unit admission post-procedure.
No postoperative complications such as biliary leaks or septic events were observed.

Conclusions:

The bipolar radiofrequency device technique is safe and feasible for liver resection.
This method simplifies the liver resection procedure.
The technique is associated with minimal morbidity and maximal preservation of liver parenchyma.
