We have studied experimentaly using mongrel dogs, for the purpose to make a artificial substitute for the complete replacement of the esophagus, useful on the clinical side.
The material of the prosthesis is collagensilicon copolymer, synthesized by some chemical and physical process. We have proved the good affinity between tissue and the copolymers by physical examination and microscopical studies.
Using the superiority of this material, we started to experiment on actual anastomosis, connecting the cervical esophagus and stomach with this prosthesis, but the result is not satisfactory just yet, because of many troublesome factors of the experiment.
