游离空肠移植颈部食管重建术

Animal experiment and clinical application of cervical esophageal reconstruction with jejunal graft

本文报告选用２０条杂种成犬行游离空肠移植颈部食管重建术。一种以空肠血管与颈总动脉及颈内静脉行端一侧吻合；一种以空肠血管与颈横动脉及颈外静脉行端一端吻合。空肠移植颈部食管重建，术后血供好，并发症少，符合生理要求。两种方法术后肠管均存活良好，且并发症发生率无明显差异。与后种方法相比，前一种方法可以克服颈部受区血管选择时可能遇到的种种困难，几乎任何情况均可选用，在使手术适应证扩大方面，有重要临床意义，且临床应用后效果满意。

This artical reported that 20 mongrels underwent cervical esophageal reconstructionwith free jejunal graft.Two different methods were introduced in our experiment. In method I,thejejunal vesseles were anastomosed to the common carotid artery and internal jugular vein.In methodⅡ,The jejunal vessels were anastomosed to the cervical transverse artery and external jugularvein.Cervical esophageal reconstruction with free jejunal graft had adequate blood supply for the je-jnum and low rate of postoperative complications in accordance with the demand of physiology.Allthe jejunal grafts survived excellently and had no significant differentiation of the postoperative compli-cation in the two methods.In compared with metod Ⅱ, method Ⅰ could overcome all kinds of difficul-ties in the selection of the cervical vessels,and it could almost be utilized under any circum-stances Thus, method Ⅰ has very impostant clinical significance in the aspect of extending operativeindication.
