vets-Pharyngeal Paralysis & Esophagitis

Pharyngeal palsy  [symptoms]:   

Sick dogs lose their swallowing ability. After eating, they are weak in chewing, have difficulty swallowing, and cannot swallow water outside their spit. Although they are inhaled into the mouth, they flow out from the nostrils. There was no swelling and pain in the pharynx, and the swallowing reflex disappeared. Sick dogs develop foreign body pneumonia due to swallowing or fail to die due to prolonged inability to eat or drink. Sometimes pharyngeal palsy is often accompanied by tongue palsy and esophageal palsy. 

【Treatment】:   

There is no effective treatment for central pharyngeal palsy. If there is peripheral nerve damage or inflammation, electroacupuncture can be used to improve the excitement of local peripheral nerves. There is a certain treatment possibility. Sick dogs should be given food and water via gastric tube to maintain their lives. 

Esophagitis [symptoms]:   

In mild cases, there is little change in food intake. In severe cases, due to pain in the esophagus, stretch the neck and raise the head when swallowing, and sometimes food, saliva, and drinking water flow out of the nostrils. Excessive salivation and vomiting. Sensitive palpation of the esophagus. 

If the deep tissue of the esophagus is inflamed, perforation of the esophagus often occurs, such as perforation of the anterior esophagus, swelling of the cervical sulcus, crepitus on palpation, severe systemic symptoms, elevated body temperature, and finally an esophageal fistula. If the posterior segment is perforated, mediastinitis, pleurisy, and systemic sepsis may occur. 

【Treatment】:   

Systemic antibiotic therapy, such as penicillin, streptomycin, and other broad-spectrum antibiotics, such as ampicillin, cephalosporin, etc. 

In order to clean the esophagus, achieve the purpose of anti-inflammatory and astringent, 0.1% potassium permanganate solution, 1% tannic acid solution, 2% boric acid solution, etc. can be injected into the esophagus with a thin gastric tube, and then a small amount of iodine glycerin (5-10ml) can be injected. 

Esophageal obstruction    [symptoms]:   

Due to the pain and compression of the esophageal obstruction, it causes strong swallowing and choking, salivation and restlessness. Sick dog tries to stretch

Neck swallowing, mouth and tongue stretched out, salivation, extremely fearful and uneasy, turning in circles. Sometimes a spastic cough may occur. Feeding and drinking are completely stopped. When the front end of the esophagus is blocked, the eaten bolus immediately leaks out of the mouth. When the blocked part of the esophagus is closer to the stomach, the reflux time is later. 

Tuberculous enlarged mediastinal lymph nodes can promote esophageal obstruction.

Incomplete obstruction often occurs inconspicuous disturbance, slow feeding, vomiting and choking action, do not eat large pieces of food, swallow carefully.

Due to esophageal obstruction due to esophageal perforation caused by sharp foreign bodies, the dog completely refuses to eat, is highly restless, straightens the head and neck, drools violently, vomits, spit out foamy mucus, bloody liquid, scratches the neck with hind feet, coughs and even chokes.

【treatment】:

The foreign body in the front end of the esophagus was attempted to be removed from the mouth and throat with forceps. If necessary, atropine 0.05mg/kg body weight injection can be used to eliminate the strongly obstructive esophageal spasm and reverse peristalsis, which is helpful for the implementation of foreign body removal surgery.

For foreign bodies in the thoracic segment of the esophagus, if the foreign body is not sharp or sharp, try an emetic (apomorphine 1-2mg per 25kg body weight in dogs, subcutaneous injection), because the foreign body can often be discharged when choking or vomiting. Foreign bodies trapped in the thoracic segment of the esophagus enter the stomach. Do not push strongly to prevent perforation of the esophagus.

In the case where the above conservative methods are ineffective, a cervical esophagus incision can be performed to remove the foreign body. For dogs with chest foreign bodies, a laparotomy can be performed to open the stomach or through the chest esophagus to remove foreign bodies.
