Summary
This study presents a successful experimental model for en bloc transplantation of the liver, duodenum, and pancreas in pigs. Early graft function, liver function, and endocrine pancreatic function were excellent post-transplant.
Area of Science:
- Surgical Innovation
- Transplantation Medicine
- Gastrointestinal Surgery
Background:
- En bloc liver, duodenum, and pancreas transplantation is a viable human treatment for upper abdominal tumors.
- Developing a reliable experimental model is crucial for advancing this complex surgical procedure.
Purpose of the Study:
- To establish and detail an experimental model for en bloc liver, duodenum, and pancreas transplantation in pigs.
- To evaluate the surgical technique, anesthetic protocol, and early graft function in this model.
Main Methods:
- Development of a surgical technique for en bloc harvesting and preservation of liver, duodenum, and pancreas.
- Implementation of a detailed surgical procedure in recipient pigs.
- Establishment of an anesthetic model and post-transplant autopsy for evaluation.
Main Results:
- Excellent early graft function observed post-transplantation.
- Normal liver function and endocrine pancreatic function within 8 hours.
- Normal absorption and insulin secretion responses in tested animals.
Conclusions:
- The developed experimental model demonstrates successful en bloc liver, duodenum, and pancreas transplantation in pigs.
- The surgical technique and preservation methods ensure excellent early graft viability and function.
- This model provides a foundation for further research into complex upper abdominal organ transplantation.
