Summary
A simplified technique for rat heterotopic small bowel transplantation (SBT) was established, achieving a 100% technical success rate and 95.6% 7-day survival. This method is effective for improving outcomes in rat SBT models.
Area of Science:
- Surgical Innovation
- Transplantation Research
- Animal Models
Background:
- Small bowel transplantation (SBT) is a complex procedure with significant challenges.
- Developing reliable animal models is crucial for advancing SBT research.
Purpose of the Study:
- To establish a simplified and effective heterotopic small bowel transplantation (SBT) model in rats.
- To provide a practical surgical technique for future SBT studies.
Main Methods:
- A simplified heterotopic SBT technique was developed using male Wistar rats.
- Grafts involved the whole small intestine with superior mesenteric artery (SMA) and portal vein (PV) pedicles.
- Revascularization utilized end-to-side anastomosis of SMA to infrarenal aorta and PV to left renal vein, with distal enterostoma.
Main Results:
- The surgical procedure averaged 130 minutes, with a mean warm ischemia time of 30 minutes.
- A 100% technical success rate was achieved for the SBT model.
- The 7-day survival rate was high at 95.6% (86/90 rats).
Conclusions:
- The simplified surgical technique is effective and practical for rat heterotopic SBT.
- This model offers improved outcomes and reliability for transplantation research.
- The technique facilitates further investigation into SBT strategies.
