| ICD-10 online (WHO version 2019) | |
As cricopharyngeale achalasia disease is referred to in the lower pharynx ( inferior pharyngeal constrictor muscle , particularly its pars cricopharyngea ) does not open properly and the bite can not enter into the esophagus. The term achalasia comes from the Greek ( achalasis , lack of slack). The disease is usually congenital and results from a defect in the neuromuscular coupling. It is usually corrected surgically by cutting or removing the affected muscle. Cricopharyngeal achalasia occurs in humans, and occasionally in domestic dogs.
The disease manifests itself as a swallowing disorder ( dysphagia ) usually immediately after the suckling period with repeated attempts to swallow, gagging, coughing and regurgitation . If the disease is complicated by aspiration pneumonia , high fever and severe general disorders can occur. The diagnosis is made on the basis of the preliminary report, the clinical examination with observation of the act of swallowing, measurement of the esophageal pressure and, if necessary, a videofluoroscopy .
Dogs will have a myotomy ( cutting of muscles) or myectomy ( removal of muscles). The prognosis is good.
