Extension large colon resection in 12 horses.

Area of Science:

• Veterinary Surgery
• Equine Medicine
• Gastroenterology

Background:

• Large colon resection is a major surgical procedure in horses.
• Indications include volvulus, thromboembolism, adhesions, and congenital defects.
• Surgical outcomes and long-term prognosis require further investigation.

Purpose of the Study:

• To evaluate the outcomes of extensive large colon resection in horses.
• To identify complications and long-term health in survivors.

Main Methods:

• Retrospective study of 12 horses undergoing 50-75% large colon resection.
• Data collected on surgical indications, duration, and postoperative complications.
• Long-term follow-up (9-18 months) for clinical and clinicopathological assessment.

Main Results:

• Five horses survived the immediate postoperative period.
• Complications included musculoskeletal issues, further infarction, ileus, and small intestinal problems.
• Four of five survivors had no long-term clinical or clinicopathological abnormalities.
• One survivor experienced diarrhea and weight loss, responsive to diet change.

Conclusions:

• Extensive large colon resection in horses carries significant risks.
• A subset of horses can achieve long-term survival with good outcomes.
• Careful patient selection and management are crucial for successful outcomes.
