摘 要: | 目的:建立简化的大鼠异位全小肠移植术技术,以提高手术成功率,为相关研究奠定基础.方法:供、受体均为雄性近交系Wistar大鼠,共180只,配对手术.采用供肠的肠系膜上动脉与受体肾下腹主动脉端侧吻合、门静脉与受体左肾静脉套管法端端吻合重建移植小肠血供,移植小肠远端腹壁造口.结果:手术耗时130min,移植小肠热缺血时间约30min.90只受全大鼠术扣即时存活率为100%,长期存活率(>7d)为95.6%.结论:简化术式具有操作简便,移植小肠的热缺血时间短,手术成功率高等优点,有利于后续研究工作的开展.

Simplified techniques in rat heterotopic small bowel transplantation |
| |
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. |
