Expimental segmental replacement of esophagus by biological tissues.
A method is described for segmental esophageal replacement in dogs, with one of three types of tissue substitute: pericardium, fascia lata and aortic homograft. The experiments involving the thoracic esophagus failed owing to the development of acute mediastinitis and sepsis. The most promising results were obtained in animals in which an aortic homograft was used to replace the cervical sigment of the esophagus. Eight of the 12 animals with aortic homograft survived and gained weight until killed one to six months after operation. The overall results suggest that aortic homograft may have a potential clinical application in cases in which esophageal replacement is necessary.
