Objective To investigate the procedures for establishing a stable model of intestinal xenotransplantation from pig to cynomolgus, with the purpose of providing a good experimental tool for the xenograft rejection study in intestinal xenotransplantation. Methods White wild-type pigs were used as donor and cynomolguses used as recipients. The procedure of segmental heterotopic intestinal xenotransplantation in recipients was performed as following: the donor`s anterior mesenteric artery was anastomosed end-to-side to the recipient`s infrarenal abdominal aorta, and the donor`s tributary of anterior mesenteric venous was anastomosed end-to-side to the recipient`s infrarenal inferior vena cave. Subsequently, both the proximal and distant ends of the graft intestine were stayed ligated. Results Segmental intestinal xenotransplantation was performed in 5 cynomolguses, with an average graft intestine length of (52.0±5.7) cm. The success rate of vascular anastomosis was 100%, and the intestinal xenograft survival was 152±72(55~245) minutes. Conclusions A stable, repeatable model of segmental intestinal xenotransplantation from pig to cynomolgus was established, which would provide an ideal tool for further research on intestinal xenotransplantation from transgenic pig to cynomolgus.
