Флуоресцентная лапароскопическая центральная гепатэктомия при раке печени с использованием индоцианинового зеленого негативного окрашивания

Overview

This protocol describes fluorescent negative staining in laparoscopic central hepatectomy, enhancing the accuracy and precision of the procedure. Surgeons can perform right plane resection with ease using fluorescence guidance.

Key Study Components

Area of Science

• Surgery
• Fluorescence Imaging
• Hepatology

Background

• Laparoscopic central hepatectomy requires precise identification of resection planes.
• Fluorescent techniques can aid in visualizing anatomical structures.
• Negative staining enhances the delineation of liver segments.
• ICG (Indocyanine Green) is commonly used for fluorescence imaging in surgical procedures.

Purpose of Study

• To improve the accuracy of anatomical hepatectomy.
• To facilitate easier surgical resection through fluorescence guidance.
• To define boundaries between liver sections clearly.

Methods Used

• Preoperative preparations were conducted.
• Liver parenchyma was separated at one centimeter on the falciform ligament's right side.
• Segments were ligated and transected for Glisson pedicle branches.
• Two milliliters of 1 to 100 diluted ICG were injected for negative staining.

Main Results

• The resection plane was accurately determined using fluorescence.
• Surgeons were able to perform right plane resections with confidence.
• The technique improved the precision of liver segment delineation.
• Fluorescent guidance enhanced surgical outcomes in central hepatectomy.

Conclusions

• Fluorescent negative staining is a valuable technique in laparoscopic hepatectomy.
• This method enhances surgical precision and safety.
• Further studies could explore its application in other surgical procedures.
