摘要
目的:改进大鼠原位小肠移植(Small bowel tansplantation,SBT)的三套管血管吻合技巧。方法:动脉吻合采用供体带肠系膜上动脉(Superior mesenteric artery,SMA)的腹主动脉(Abdominal aorta,AA)段两端与受体的腹主动脉套管吻合,静脉吻合采用供体的肝门静脉(Hepatic portal vein,HPV)与受体左肾静脉套管吻合。结果:60例接受小肠移植的大鼠存活率为93.3% (56/60),整个手术用时1.5~2h,其中动脉吻合用时(4±1)min,静脉吻合用时1min,动、静脉吻合共用时(4±2)min。结论:改进三套管血管吻合技巧既加快了吻合速度,缩短了手术时间,又减少了手术并发症,提高了手术成功率。
Objective:To improve the surgical skill of Tri-cuff vascular anastomosis of the rat small intestinal transplantation. Methods:Artery anastomosis was done by employing the cuff anastomosis between a segment of donor abdominal aorta with superior mesenteric artery and recipient abdominal aorta.Venous anastomosis was done by employing the cuff anastomosis between dornor's vein and recipient's left renal vein. Results:The survival rate in 60 rats with small intestinal transplantation was 93.3% (56/60).Total operation time was aboutl,5-2h. The average times for the arterial anastomosis and venous anastomosis were (4 + 1 )min and 1 min respectively, Conclusion:The modified skill of Tri-cuff vascular anastomosis for the orthotopic small bowel transplantation in rats speeds the vascular anastomosis and shortens the operation time,reduces the complications of the operation.and improves the operation survival rate.
