________________________________________________________________________________ ResumoA acalasia cricofaríngea é uma doença que gera diminuição do relaxamento da musculatura esofágica. Como consequência, ocorre a interrupção da passagem do bolo alimentar da orofaringe através do esfíncter esofágico cranial. Relata-se o caso de um cão Golden Retriever que, após anamnese e avaliação clínica, foi diagnosticado através de radiografia contrastada como portador de acalasia cricofaríngea. O tratamento foi cirúrgico, através de técnica de miectomia cricofaríngea, onde retirou-se o músculo cricofaringeano. Observou-se resultado favorável na correção cirúrgica. O paciente foi acompanhado durante seis meses após o procedimento e garantiu-se que não houve recidiva de sinais clínicos.
AbstractCricopharyngeal achalasia is a disorder that causes decrease in the muscle relaxation of the esophageal musculature. As consequence, the food bolus has its passage interrupted at the oropharynx, through the cranial esophagus sphincter. This work reports the case of a Golden Retriever dog, which after anamnesis and clinical evaluation, was diagnosed through contrast radiography with Cricopharyngeal Achalasia. The treatment consisted in surgery, using the cricopharyngeal myectomy technique. The results of the surgery were favorable, and the patient was monitored for six months after the procedure, ensuring that there was no recurrence of clinical signs.
