简介：
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.
What is fluorescent negative staining?
Fluorescent negative staining is a technique used to enhance the visibility of anatomical structures during surgery.
How does ICG work in this procedure?
ICG is injected to provide contrast, allowing surgeons to visualize the boundaries of liver segments more clearly.
What are the benefits of using fluorescence in surgery?
Fluorescence improves accuracy, reduces the risk of complications, and enhances the overall surgical outcome.
Is this technique applicable to other types of surgeries?
Yes, fluorescent techniques can be adapted for various surgical procedures to improve visualization.
What preparations are needed before the procedure?
Preoperative preparations include patient assessment and planning the surgical approach based on imaging studies.
Can this technique be used in open surgeries?
While primarily used in laparoscopic procedures, fluorescent techniques can also be applied in open surgeries.
