Abstract
We transplanted 4-5cm artificial esophagus of canine neck esophagus by Expanded Polytetra-fluoroethylene (EPTFE).
Five dogs were treated, only two dogs were long survived with slightly stenosis, but they had not silver disphagy.
We treated stenosis area by endoscopic cutting without traditional extension method, this new extension method of cutting was every easy and recurrence was slightly.
After one month postoperation, its inner surface of artificial esophagus was covered with reproduce mucosa, and it looked like normal mucosa.
In the future, we will transplant this artificial esophagus from neck to stomach as by-pass with unresectiable esophagial carcinoma patients.
