Summary

A large cholelith caused duodenal obstruction in a 10-year-old Appaloosa stallion, leading to colic and intestinal rupture. Multiple gallstones were found in bile ducts and stomach during necropsy.

Area of Science:

  • Veterinary Medicine
  • Equine Surgery
  • Gastroenterology

Background:

  • Colic is a common emergency in horses, often requiring surgical intervention.
  • Duodenal obstruction can lead to severe complications and is a critical surgical condition.
  • Choleliths (gallstones) are rare causes of gastrointestinal obstruction in horses.

Observation:

  • A 10-year-old Appaloosa stallion presented with colic, elevated vital signs, and abdominal pain.
  • Nasogastric intubation yielded 15 liters of reflux, indicating upper gastrointestinal obstruction.
  • Rectal palpation revealed an abdominal mass, later identified in the ascending duodenum during exploratory laparotomy.

Findings:

  • Exploratory laparotomy revealed a large cholelith obstructing the ascending duodenum.

Related Experiment Videos

  • The small intestine ruptured during surgical manipulation at the obstruction site.
  • Necropsy confirmed the presence of multiple choleliths in the pancreatic and common bile ducts, as well as the stomach.

    • Implications:

    • This case highlights cholelithiasis as a potential, albeit rare, cause of duodenal obstruction in horses.
    • Prompt diagnosis and surgical intervention are crucial for managing obstructive colic.
    • Understanding the prevalence and impact of choleliths can improve diagnostic and treatment strategies for equine colic.
