Summary
This study details a reliable orthotopic liver transplantation model in rats, achieving high surgical success and survival rates. This rat liver transplant model is suitable for future research in the field.
Area of Science:
- Surgical Innovation
- Transplantation Research
- Animal Models
Background:
- Orthotopic liver transplantation is a critical procedure for end-stage liver disease.
- Developing reliable animal models is essential for advancing transplantation techniques and understanding outcomes.
Purpose of the Study:
- To establish and validate a reproducible orthotopic liver transplantation model in rats.
- To assess the surgical success and short-term survival rates of this model.
Main Methods:
- 300 orthotopic liver transplantations were performed in male rats (Lewis, ACI, Wistar, SD).
- Standardized surgical techniques included abdominal incision, liver perfusion, bile duct reconstruction (end-to-end anastomosis), and vascular anastomoses (cuff technique for infrahepatic vena cava and portal vein; suture or cuff for suprahepatic vena cava).
Main Results:
- An overall operative success rate of 92.7% (278/300) was achieved.
- A 1-week survival rate of 88.4% (199/225) was observed in isografting experiments.
- The model demonstrated reliability for subsequent liver transplantation studies.
Conclusions:
- The described orthotopic liver transplantation technique in rats is a reliable and reproducible model.
- This model provides a valuable platform for investigating various aspects of liver transplantation.
