Summary

Minimizing blood loss during laparoscopic liver resection is challenging. A modified two-surgeon technique with distinct "transection" and "hemostatic" modes allows for rapid and secure liver parenchymal transection, comparable to open surgery.

Area of Science:

  • Hepatobiliary Surgery
  • Minimally Invasive Surgery
  • Surgical Techniques

Background:

  • Minimizing intraoperative blood loss is crucial in liver resection.
  • Controlling refractory bleeding is more difficult in laparoscopic liver resection compared to open surgery.

Purpose of the Study:

  • To present a modified two-surgeon technique for laparoscopic liver resection.
  • To enable rapid and secure laparoscopic liver parenchymal transection comparable to open resection.

Main Methods:

  • Modification of the two-surgeon technique for laparoscopic liver resection.
  • Implementation of independent "transection mode" and "hemostatic mode".
  • Rigid switching between modes based on surgical field conditions for effective role sharing.

Main Results:

  • Achieved rapid and secure laparoscopic liver parenchymal transection.
  • Demonstrated hemostasis comparable to open liver resection.
  • Facilitated satisfactory parenchymal transection and hemostasis.

Conclusions:

  • The modified two-surgeon technique improves safety and efficiency in laparoscopic liver resection.
  • This approach allows for comparable speed and security to open liver resection.
  • The technique is beneficial for training surgical teams and young surgeons.
