Signalment

Can affect both dogs and cats.

Description

Abnormal gastric motility has been cited as a contributing factor of conditions such as gastric dilatation-volvulus and gastric outflow obstruction that has resulted from pylorospasm. Many potential causes of gastric stasis have been proposed:

nervous inhibition due to pain or trauma
electrolyte or acid-base imbalances
uraemia
hypothyroidism
hepatic encephalopathy
pancreatitis
inflammation or ulceration of the stomach
anticholinergic drugs and narcotic analgesics used to treat vomiting and diarrhoea
idiopathic

Diagnosis

Diagnosis of gastric motility disorders is usually made once other causes of vomiting have been ruled out. The normal gastric emptying time of a dog is 10-12 hours. Therefore, a dog that vomits an undigested meal more than twelve hours after feeding should be strongly suspected of having a gastric motility disorder if an outflow obstruction and inflammatory disease have been excluded. =

Clinical Signs=

chronic belching and vomiting
anorexia
weight loss
poor body condition

Radiography

Contrast radiography may support a diagnosis of a gastric motility disorder:

Retention of a barium meal for more than 10 hours

Biopsy

Endoscopy

Treatment

Prognosis
