Summary

The bipolar vessel sealing device effectively controlled bleeding during liver resections in patients with normal liver parenchyma. However, it was less effective in patients with cirrhotic livers, indicating a need for caution in such cases.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Technology
  • Hemostasis Devices

Background:

  • Significant blood loss during liver resection poses a risk of morbidity and mortality.
  • Effective hemostasis during parenchymal transection is crucial for minimizing complications.
  • Various surgical techniques and devices aim to reduce bleeding during liver surgery.

Purpose of the Study:

  • To evaluate the safety and efficacy of a bipolar vessel sealing device for liver transection.
  • To determine if this device can achieve satisfactory hemostasis and reduce blood loss.
  • To assess its impact on intraoperative and postoperative complications in liver resections.

Main Methods:

  • A prospective study involving 30 patients undergoing liver resection (major and minor).

Related Experiment Videos

  • The bipolar vessel sealing device was used for parenchymal transection, employing a crush technique followed by energy application.
  • Inflow occlusion was not routinely used, and no other hemostasis devices were applied.

    • Main Results:

    • The device achieved hemostasis in 27 out of 30 patients (90%).
    • Median blood loss was 250 ml, with 17% of patients requiring intraoperative transfusions.
    • No postoperative hemorrhage, bile leaks, or abscesses were observed; the overall complication rate was 17%.

    Conclusions:

    • The bipolar vessel sealing device is a useful tool for liver resection in patients with normal liver parenchyma.
    • Its effectiveness is limited in patients with cirrhotic livers, where its use should be avoided.
    • The device facilitates careful liver transection, achieving satisfactory hemostasis and potentially reducing complications.
