Esophageal ligation was performed in six dogs with hard rings that could be elimited. Long - term effects were studied by means of radiology, endoscopy, manometry and pathological anatomy. The period ever which this evaluation was carried out were 21 and 142 days.Findings revealed that there had been complete section of esophagus with amputation o'f all planes; it had healed in the shape of a ring and was well epithelized.No removed organic stenosis was found. Stenosis suggested by radiology -which was not ratified by endoscopy- is probably consecutive to dyskinetic disturbances.

Se colocó a seis perros un anillo rígido eliminable para ligadura die esófago. Se estudiaron las consecuencias con radiología, endoscopía, manomeüría y anatomía patológica a largo plazo. Los plazos de esta valoración fueron de 21 y142 días.Se encontró que la sección completa del esófago había amputado todos los planos, estaba cicatrizada en forma anular y bien epitelizada. No existía estenosis orgánica a largo plazo. La estenosis sugerida por la radiología, y noratificada por la endoscopía, probablemente sea consecutiva a transtornos disquinéticos.
