Liver resection with a new multiprobe bipolar radiofrequency device

Area of Science:

• Hepatobiliary surgery
• Minimally invasive surgical techniques
• Radiofrequency ablation technologies

Background:

• Liver resections can involve substantial intraoperative blood loss, posing a significant surgical challenge.
• Effective methods to minimize blood loss during hepatectomy are crucial for improving patient outcomes.

Purpose of the Study:

• To evaluate the efficacy of a novel multiprobe bipolar radiofrequency device (Habib 4X) in reducing intraoperative blood loss during liver resection.
• To assess the safety and effectiveness of this device in both minor and major hepatectomies.

Main Methods:

• A prospective study was conducted involving 62 patients undergoing liver resection for metastatic cancer.
• The Habib 4X radiofrequency device was used for liver parenchyma transection.
• Key outcome measures included intraoperative blood loss, transection time, and complications.

Main Results:

• The study included 51 minor and 11 major hepatectomies.
• Mean blood loss was 4.8 mL/cm², and mean transection time was 39 seconds/cm².
• No hepatic inflow occlusion was required, only one patient needed a blood transfusion, and the morbidity rate was 18%.

Conclusions:

• The novel bipolar radiofrequency device facilitates liver resections with minimal blood loss.
• The Habib 4X device is associated with low transfusion requirements, reduced mortality, and lower morbidity rates.
• This technology offers a promising approach for safer and more efficient liver surgeries.
