目的探讨游离空肠移植下咽及颈部食管重建术中常见并发症及其防治措施。方法选用10条比格犬(Beagle)行游离空肠移植下咽及颈部食管重建术,术中以空肠血管与甲状腺前动脉及颈外静脉行端-侧、端-端吻合,空肠移植颈部下咽、食管重建,观察并发症发生情况。结果术后6条实验犬手术成功,存活4w以上并能够正常饮食,术后移植空肠血供良好;4条犬出现并发症而死亡。结论游离空肠移植技术可以重建颈部组织缺损的修复,术前准备充足、术中操作细腻、术后观察及护理及时可以减少并发症,提高手术成功率,是颈部缺损修复最为理想的方法。
Objective To investigate the common complications and prevention and treatment of pharyngeal and cervical esophageal reconstruction under free jejunal transplantation. Methods Ten Beagle dogs were treated with free jejunal transnasal esophagectomy and neck esophagectomy. The jejunal vessels were anastomosed with the anterior thyroid artery and external jugular vein during operation. Swallow, esophageal reconstruction, observe the incidence of complications. Results Six experimental dogs were successfully surgically treated and survived for more than 4 weeks and were able to eat normally. The blood supply of jejunum after transplantation was good. Four dogs died of complications. Conclusion The technique of free jejunum transplantation can reconstruct the defect of cervical tissue. The preoperative preparation is adequate, the intraoperative operation is delicate, the postoperative observation and nursing can reduce the complications in time, and improve the success rate of operation. It is the most ideal method to repair neck defects.
