This study presents a new surgical technique for right segmental liver resections, standardizing the intrahepatic approach to the portal pedicle. The method proved feasible with minimal blood loss and no postoperative deaths, offering excellent immediate results.

Area of Science:

  • Hepatobiliary Surgery
  • Surgical Oncology
  • Minimally Invasive Procedures

Background:

  • Indications for segmental liver resections are growing.
  • Current techniques include deep wedge transection or intrahepatic approaches.
  • A systematized intrahepatic approach to the portal pedicle is needed.

Purpose of the Study:

  • To present a systematized intrahepatic surgical technique for right segmental liver resections.
  • To evaluate the feasibility and outcomes of this novel approach.

Main Methods:

  • Developed and applied an original surgical technique involving 3 small incisions around the hilar plate.
  • Performed right segmental liver resections in 14 consecutive patients.
  • Standardized the approach to reach the right posterior and anterior sheaths.

Main Results:

  • The technique was feasible in all 14 patients undergoing right segmental liver resection.
  • Intraoperative blood loss was minimal, with 11 patients not requiring transfusion.
  • No postoperative deaths were recorded.

Conclusions:

  • The described operative procedure standardizes the intrahepatic approach to the right portal pedicle for right segmental resections.
  • This technique may reduce bleeding and the need for pedicle clamping.
  • It facilitates recognition of liver sheaths, yielding excellent immediate results.
