Abdomen and Upper GI

x-ray

Abdomen:

The stomach is markedly distended with fluid and gas. Within the viewable portion of the caudal thorax, heavy interstitial and alveolar infiltrates are identified caudoventrally. The caudal thoracic esophagus is also markedly gas distended.

Upper GI:

A total of 750 mls of barium contrast solution and 750 mls of water were given orally. At 5 hours post administration, there has been no significant passage of contrast medium into the duodenum.

Impression:

Mechanical or functional obstruction of the upper GI tract. Megaesophagus may be secondary to esophagitis or poor motility. Aspiration pneumonia.

Gastroscopy

Photograph

On gastroscopy, the stomach was severely ulcerated. The large amount of gastric fluid prevented visualization of the duodenum.

Case Discussion

Endoscopy showed severe ulceration of the esophagus and stomach. Ultrasound of the abdomen showed an enlarged stomach, and thickening of the duodenum with suspected stricture formation. Abdominal surgery was performed, and a jejunal gastric anastomosis was performed.

The colt was treated for aspiration pneumonia which resolved over the next two months. The ulceration also resolved on recheck endoscopy.
