摘要
目的：改进大鼠胰十二指肠移植动物模型，控制失血性休克的发生，增加术后成功率。
方法：供体门静脉同受体左肾静脉利用“卡夫”管相吻合。可以避免术中受体肝素化而导致血管吻合口渗血。给受体输注供体新鲜血2.5-3 ml.
结果：65例药物诱导糖尿病大鼠行胰十二指肠移植。60例成活超过7天，成功率92.3%，非禁食情况下，血糖浓度均正常。
结论：该模型的技术改进减少许多并发症，大大提高了手术成功率。

ABSTRACT
Objective To refine the technique of Lee’s pancreaticoduodenal transplantation in the rat1, to overcome hypovolemic shock, to enhance the success rate.
Methods We reconstructed the venous anastomosis by a “cuff” anastomosis between the donor portal vein and the recipient renal vein. Meanwhile, we injected the recipient 2.5-3 ml fresh blood which was taken form the donor.
Results Of 65 transplanted rats that were induced diabetes, 60 rats survived over 7 days, the success rate was 92.3%. All success rats were euglycemia.
Conclusions Our fefined techniques could eliminate most surgical complications, allowing the pancreaticoduodenal transpiantations in the rat with a high degree of success.
