We have reported about our experimental study on artificial esophagus made of collagen-silicone copolymer.
We could make sure that the artificial esophagus was exellent for preventing the leakage of the anastoimsis.
But it is difficult to prevent the narrowness at the new esophagus, that would occur in the cases of long survivals.
In this report, we showed two cases of the narrowness, that prosthesis had removed at one month and seven months after operation.
It might be difficult to make out the perfect artificial esophagus enough to use in clinical case without changing the model of the prosthesis.
