Abstract
We examined an artificial esophagus with the expanded polytetrafluoroethlene (EPTFE) with beagle dogs and Australia-White rabbits. The grafts were reinforced with polyehylene rings, and were implanted 3 cm at the neck in two dogs, 1cm in three rabbits. One dog was succeeded in surviving for more than two months, another one died for the endoscopic technical failure at postoperative 6 weeks. Three rabbits could not succeeded in surviving for more than two weeks, because of IVH technical failure, leakage and poorly general condition. The inner surface of the grafts were progressively covered with regenerating mucosa in rabbits. We observed, the graft fell down into the stomach for leakage in one autopsy dog.
