      Traumatic perforations of the cervical and thoracic esophagus were produced with 7 to 12 mm. bronchoscopes in 25 dogs. Only 2 deaths were the result of mediastinitis; the other 23 animals were sacrificed at varying intervals up to 3 weeks after perforation. One animal had a local abscess and another had a small sinus tract but both had sealed perforations. The other 21 animals had a healed perforation with little inflammatory reaction. The basis for this surprising tolerance to traumatic perforation in the dog is unknown and is under investigation at this time.
