A surgery technique of gastroyeyunostomy was applied in dogs with experimental pyloric stenosis to observe the transit of chyle through the new path, and to evaluate the adverse effects on the animal. Ten crossbred dogs (5 female and 5 male) of 2-3 years old were surgically pyloric stenosed and the gastroyeyunostomy was performed. Animals were clinically evaluated for 35 days, and then, contrast radiographs were taken before necropsy. The post-surgery clinical observations shown an adequate recovery by day 10 after surgery. Vomit, an important clinical sign was evaluated. Animals were grouped as “bad” for recurrent vomits, “good” for occasional vomits, and “excellent” for animals apparently normal. 33% of dogs were considered as “good” and 67% as “excellent”. An adequate outflow of contrast liquid through the anastomosed organs was observed in all animals. There were ...

Se expone la técnica quirúrgica de gastroyeyunostomía en caninos con estenosis pilórica experimental para observar el tránsito de quilo a través de esta vía alterna y evaluar los posibles efectos adversos que ocasione en el animal. Se utilizaron 10 caninos mestizos (5 hembras y 5 machos) de 2 a 3 años de edad, a los que se les estenosó el píloro utilizando una ligadura de seda y luego se les realizó la técnica quirúrgica de gastroyeyunostomía. Se evaluaron por 35 días post-operatorios, y al final se les tomó radiografías de contraste y se les practicó la necropsia. La observación clínica mostró que los animales se recuperaron dentro de los 10 días de la cirugía. El vómito, signo cardinal en los casos de estenosis pilórica fue evaluado, y los animales se agruparon por el análisis en base a este signo como “malos” si el vómito era recurrente, “buenos” si ...
