Laparoscopic Anatomical Hepatectomy Using Takasaki’s Approach and Indocyanine Green Fluorescence Navigation

Overview

This study presents a protocol for laparoscopic anatomical hepatectomy utilizing Takasaki's approach and indocyanine green fluorescence navigation for S4/5/7/8 resection. The technique aims to enhance surgical accuracy and minimize blood loss during liver resection.

Key Study Components

Area of Science

• Neuroscience
• Surgical Techniques
• Fluorescence Navigation

Background

• Takasaki's approach involves extrahepatic pedicle occlusion to ensure tumor-free margins.
• Indocyanine green staining is used for better visualization during surgery.
• Minimizing blood loss is crucial for patient safety and recovery.
• Intraoperative ultrasound aids in identifying lesions not detected preoperatively.

Purpose of Study

• To improve the accuracy of anatomical liver resection.
• To minimize intraoperative blood loss.
• To ensure clear tumor margins during resection.

Methods Used

• Application of Takasaki's extrahepatic pedicle occlusion technique.
• Use of indocyanine green for fluorescence navigation.
• Intraoperative ultrasound for tumor localization and margin marking.
• Pringle maneuver to occlude hepatic inflow during surgery.

Main Results

• Estimated blood loss was 150 milliliters, indicating minimal hemorrhage.
• Total surgical duration was 205 minutes, within expected ranges.
• Patient discharged after six days without complications.
• Postoperative drainage decreased significantly, indicating stable recovery.

Conclusions

• The protocol demonstrates effective techniques for laparoscopic liver resection.
• Indocyanine green enhances visualization and accuracy during surgery.
• Overall outcomes suggest a safe and efficient approach to liver resection.
