Auto-alloplastics closure of cervical esophageal fistulae

The authors performed auto-alloplastic replacement with flap through a round incision, 20 to 22 in mm diameter, to elaborate a suitable method for closing the fistulae which may from during cervical esophageal operations. Of the animals three died due to other causes, the others could be evaluated, and, although the operated esophagus had not been relieved from inner pressure, after 24 hours the animals were capable of drinking, later eating. The auto-alloplastic flap was followed up by histological examination for six months.
