The behaviour of the silicone prosthesis was evaluated in replacement of a cervical oesophagus segment in five dogs, They were submitted to an operation, where a part of the oesophagus of approximately 2cm of length was excised and substituted by silicone tube with similar diameter, but greater length. These animals were observed for thirty days. They were sacrified and necropsied at end of this period. At the harvest of the oesophagus the growth of the tissue around the prosthesis was observed.
