The Ligasure vessel sealer in liver resection: a pilot study

Area of Science:

• Hepatobiliary surgery
• Surgical oncology
• Minimally invasive surgery

Background:

• Hemorrhage is a primary complication in liver resection.
• Alternative energy sources are increasingly used for vascular control.
• Electrosurgery poses risks of charring and charring.

Purpose of the Study:

• To evaluate the efficacy of alternative energy sources in sealing ductal structures during liver resection.
• To assess the potential for minimizing blood loss using these devices.
• To compare outcomes with traditional electrosurgery.

Main Methods:

• 116 patients underwent liver resection between 1994 and 2003.
• The Ligasure device was used to seal arteries, veins, and bile ducts.
• Hepatic parenchymal division was marked with a diathermy-scored line.

Main Results:

• Median blood loss was 430 mL, with a range of 100-3000 mL.
• Only 32 patients received preoperative blood transfusions.
• Perioperative mortality was nil, and 12% experienced major postoperative complications.

Conclusions:

• The Ligasure device provides a high-burst strength vessel seal up to 7mm in diameter.
• This technique is simple, rapid, and safe for parenchymal division in hepatectomy.
• The use of bipolar electrothermal energy minimizes blood loss during liver resection.
