Dog Medical Diseases – Esophageal Infarction

Esophageal infarction


First, excessive hunger, rush to eat, large mouthfuls of food swallowed without adequate chewing, or disturbed by eating, suddenly swallowing with head up and so on.

Second, the esophagus is blocked by swallowing foreign objects such as gloves or wooden balls due to playing.

Third, the feed is mixed with bone pieces, meat pieces, fish bones, etc., which cause blockage when eating. Esophageal infarction can occur in any part of the esophagus, but it is most likely to occur at the entrance to the thoracic cavity of the esophagus, the bottom of the heart, and the place where the esophagus enters the hiatus.

Diagnosis points

When the esophagus is incompletely infarcted. Sudden onset, the sick dog showed mild agitation, vomiting and choking, slow feeding, refusal to eat large pieces of food (meat, bones), and pain when swallowing. When completely infarcted and blocked by a sharp foreign body, the sick dog suddenly refuses to eat, is highly restless, straightens his head and neck, drools a lot, chokes or vomits, spit out foamy liquid and blood, and often scratches the neck with hind limbs or occurs. Cough. Even suffocation.

The diagnosis can be confirmed based on the medical history and the sudden occurrence of special symptoms, combined with the discovery of the obstructed site with gastric tube exploration. If possible, X-ray fluoroscopy or photography can be done to determine the specific location.


First, the feeding must be regular and quantitative, and not be too hungry. It should be fed to the bones after other foods have been eaten. During training, prevent dogs from eating foreign objects by mistake.

Second, a mild infarction often heals after choking or swallowing for many times, the obstruction is spit out or enters the stomach by itself. Most of them require treatment. You can administer 10-20 ml of liquid paraffin or vegetable oil first, and then subcutaneously inject pilocarpine nitrate (pirocarpine nitrate) at a dosage of 3-20 mg/time. After a few hours, some can be cured. You can also use a thin gastric tube to carefully push the foreign body into the stomach after administering liquid paraffin. Or connect an inflator to the gastric tube and pump up rhythmically. When the esophagus is dilated, use the gastric tube to slowly push the obstruction into the stomach. If the above treatment is invalid, the foreign body can be removed with an esophageal endoscope and foreign body forceps. If necessary, perform an esophagotomy to remove the infarct.
