Modified Two-Surgeon Technique for Laparoscopic Liver Resection

While minimizing intraoperative blood loss during liver resection is one of the most important tasks, it is more difficult to control the refractory bleeding during laparoscopic liver resection than with an open approach. We herein provide a modification of the two-surgeon technique that enables laparoscopic liver parenchymal transection to be performed as quickly and securely as open liver resection. To achieve proper "role sharing," the "transection mode" and the "hemostatic mode" are independent sets in place in this procedure, and these modes are switched rigidly according to the surgical field condition. By thoroughly sharing the roles, rapid laparoscopic liver parenchymal transection comparable to open liver resection can be accomplished. The present modified approach achieves satisfactory transection and hemostasis of the liver parenchyma and is also advantageous for teaching young surgeons and the entire surgical team.
