Chromicised aortic allografts for oesophageal reconstruction in dogs: An experimental study

The study was undertaken to evaluate chrome processed canine aortic tissue for cervical oesophagoplasty in dogs. Twelve adult mongrel dogs of either sex were divided equally in two groups. Surgical implantation of the graft over an experimentally created defect in cervical oesophagus was performed under general anaesthesia in all the dogs. Postoperatively, hyperalimentation intravenously and through pharyngostomy tube were employed in one group of dogs each. The clinical, physiological, haematological, biochemical and radiological studies revealed that the chrome processed canine aortic tissue is a suitable biomaterial, well tolerated by the dogs for reconstructive surgery of oesophagus.
