Radiofrequency-assisted liver resection (RF-LR) offers a safe, bloodless method for liver surgery, reducing complications and hospital stays. This technique is particularly beneficial for cirrhotic patients undergoing complex liver resections.

Area of Science:

  • Hepatobiliary Surgery
  • Minimally Invasive Techniques
  • Oncology

Background:

  • Surgical resection is standard for liver cancer and lesions, but blood loss is a major complication.
  • Radiofrequency-assisted liver resection (RF-LR) aims to minimize blood loss during liver parenchymal transection.

Purpose of the Study:

  • To evaluate the safety and efficacy of RF-LR using the Cool-Tip RF device for liver resections.
  • To assess blood loss, operative time, complications, and patient outcomes.

Main Methods:

  • A prospective study of 46 patients undergoing RF-LR between May 2005 and April 2007.
  • Procedures included major and minor hepatectomies for various liver diseases, with no hepatic inflow occlusion used.

Main Results:

Application of Laparoscopic Hepatectomy Combined with Intraoperative Microwave Ablation in Colorectal Cancer Liver Metastasis

Published on: March 3, 2023

  • Median blood loss was 100ml, with only one patient requiring transfusion.
  • Median transection time was 35 minutes; common complications included biliary fistulas and wound infections.
  • Median postoperative hospital stay was 6 days, with a median follow-up of 12 months.

Conclusions:

  • The Cool-Tip RF device enables safe, bloodless liver resections.
  • RF-LR is indicated for cirrhotic patients and challenging hepatectomies, such as segment VIII and central resections.
