Examination method of the dog’s esophagus

It is also common for the dog to get food stuck in the throat due to improper feeding by the owner. An esophageal test should be performed when a dog has difficulty swallowing, drools a lot, and is suspected of having an esophageal disease. The methods of examination can be divided into visual examination and palpation, and exploratory examination is necessary for the examination of the chest and abdomen esophagus.


1. Visual diagnosis:

The neck of the dog is marked by localized swelling of the esophagus, usually obstructed or dilated.

2. Palpation:

To palpate the esophagus, the examiner stands on the left side of the dog’s neck, facing the dog’s tail, then places his left hand on the right cervical groove to secure the dog’s neck, then uses the tip of his right finger to move down the left cervical groove from top to bottom to know the entrance to the chest, pressurizing and sliding touch, and moving down at the same time. During the touch, the examiner feels for swelling or foreign bodies, stiffness, and fluctuations in the dog’s body. When we touch the neck groove of the dog, we feel hard objects, and the esophagus may be blocked by food. When the upper part of the obstruction causes esophageal dilatation and the accumulation of a large amount of liquid, we palpate the local sense of fluctuation. When there is a painful response to touch, the dog’s esophagus may be inflamed.

3. Exploration:

During the examination, the stomach can also be explored at the same time. Firstly, it is used for the diagnosis of esophageal diseases and gastric dilatation, so as to determine the location of esophageal obstruction, stenosis, and inflammation, and to indicate whether there is gastric dilatation.


4. Significance of esophageal and gastric exploration:

If the probe encounters resistance in the esophagus and cannot be sent further, then it is caused by obstruction of the esophagus. After the probe is sent to the esophagus if the dog shows a desperate struggle to get rid of the examination and is often accompanied by a continuous cough, it is a painful reaction of the esophagus, which is commonly seen in esophagitis; When the probe tube is pushed in the esophagus, it feels great resistance. However, it can be successfully sent after using the thin probe tube, indicating that the diameter of the esophagus is smaller, which is commonly seen in esophageal stricture. After the probe was sent to the esophagus, it could not go forward in a certain section, but could pass smoothly after adjusting the Angle, indicating the possibility of esophageal diverticulum; After the probe is inserted into the stomach, a large amount of sour and smelly gas is discharged from the mouth of the tube, indicating acute gastric dilatation.
