Radiographic contrast gastrointestinal study of the neonatal llama

Area of Science:

• Veterinary Radiology
• Llama Neonatal Care
• Gastrointestinal Physiology

Background:

• Understanding normal gastrointestinal (GI) tract radiographic appearance in neonatal crias is crucial for diagnosing abnormalities.
• Limited data exists on the normal radiographic transit times for the GI tract in neonatal llamas.

Purpose of the Study:

• To describe the normal radiographic appearance of the neonatal llama GI tract.
• To determine the transit times of barium through the various segments of the neonatal llama GI tract.

Main Methods:

• Survey and contrast radiography were performed on six healthy neonatal llama crias.
• Abdominal radiographs were obtained in right lateral and dorsal recumbency at intervals after orogastric barium administration.
• Identifiable GI segments included the stomach (three compartments), duodenal ampulla, small intestine, and colon (ascending, spiral, descending).

Main Results:

• Barium rapidly entered all three stomach compartments and the proximal small intestine following orogastric intubation.
• The overall transit time through the intestinal tract was longer than anticipated.
• No emptying of the ascending colon and beyond was observed, even up to 72 hours post-administration.

Conclusions:

• This study provides a radiographic reference for the normal neonatal llama GI tract.
• The prolonged GI transit time noted warrants further investigation and consideration in clinical assessments.
• Recommendations for radiographic monitoring frequency are provided based on observed transit patterns.
