Summary

Identifying the middle hepatic vein (MHV) early during liver resection ensures a precise transection plane. This technique improves tumor-free margins and preserves liver function, reducing complications.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Anatomy
  • Liver Transplantation

Background:

  • The middle hepatic vein (MHV) is a critical landmark in liver surgery.
  • Accurate identification of the MHV is essential for safe liver transection.
  • Current techniques may lose guidance if the MHV's course is unclear.

Purpose of the Study:

  • To describe a precise liver transection technique guided by the middle hepatic vein.
  • To evaluate the benefits of early MHV exposure and tracking during hepatectomy.

Main Methods:

  • Early intraoperative exposure of the middle hepatic vein.
  • Following the MHV's course towards the inferior vena cava to establish a transection plane.

Main Results:

Laparoscopic Anatomic S7+S8d Resection Preserving Inferior Right Hepatic Vein and S6 with Right Hepatic Vein Transection

Published on: December 30, 2025

  • Achieved a precise liver transection plane.
  • Facilitated adequate tumor-free resection margins.
  • Minimized damage to intrahepatic portal pedicles and preserved venous drainage.

Conclusions:

  • Early identification and tracking of the MHV provide a reliable method for liver transection.
  • This approach enhances oncologic outcomes and preserves functional liver parenchyma.
  • The technique shows potential for reducing postoperative complications like infection.
