Abstract:
Objective:To establish a simplified heterotopic whole small bowel transplantation model in rat.Methods:Ninety pairs of inbred male Wistar rats were used as donors and recipients.The whole small intestine with a vascular pedicle composed of superior mesenteric artery and portal vein was harvested as the graft.After left nephrectomy of recipient,revascularzation of graft was accomplished by end-to-side anastomosis between donor superior mesenteric artery and recipient infra-renal aorta using a 9-0 continuous suture and an end-to-end anastomosis between the donor portal vein and left renal vein of the recipient with the cuff technique.The proximal end of the graft was ligated and the distal end was exteriorized to form an enterostoma.Results:Average time of an operation was 130 min and the mean warm ischemia time of grafts was 30 min.The successful rate of this model was 100% and 86(95.6%) recipients survived longer than 7 days after operation.Conclusion:The simplified techniques we used was effective and parcticable in improving successful rate of rat heterotopic small bowel transplantation.
