Area of Science:

  • Hepatobiliary Surgery
  • Minimally Invasive Surgery
  • Surgical Technology

Background:

  • Parenchymal liver transection is a critical step in liver surgery.
  • Existing devices for laparoscopic liver dissection have limitations.
  • The optimal technique for safe laparoscopic liver resection remains undefined.

Purpose of the Study:

  • To describe and evaluate the combined use of an ultrasonic dissector and an ultrasonic coagulating cutter for laparoscopic liver resection.
  • To assess the safety and efficacy of this combined technique.

Main Methods:

  • Laparoscopic liver resection was performed using a combination of an ultrasonic dissector and an ultrasonic coagulating cutter.
  • The ultrasonic dissector was utilized to fracture liver parenchyma.

  • Bridging structures were sealed using the ultrasonic coagulating cutter.

    • Main Results:

    • The combined technique allowed for safe dissection of liver parenchyma.
    • Minimal surgical complications were observed.
    • Low blood loss was achieved during the procedures.

    Conclusions:

    • The combined use of ultrasonic dissector and ultrasonic coagulating cutter is a safe and effective method for laparoscopic liver resection.
    • This technique offers advantages of minimal complications and reduced blood loss.
    • Further research may validate this approach as an ideal technique.
