Summary
# Editorial Summary Colic remains the leading cause of equine emergency intervention and euthanasia, yet rapid differentiation between medical and surgical cases remains challenging despite available diagnostic tools. Tharwat and Al-Sobayil's comprehensive review synthesises current knowledge on sonographic evaluation across the spectrum of equine abdominal pain, encompassing gastrointestinal conditions (spasmodic, impactive, flatulent, strangulating, and obstructive colic; gastric impaction; sand colic; verminous mesentitis; peritonitis; hernias) and non-gastrointestinal causes (cystitis, urine retention, and abdominal abscesses). Abdominal ultrasonography emerges as the most effective ancillary diagnostic tool for distinguishing between these aetiologies, with the review emphasising that classic clinical indicators—moderate to severe pain response, pain recurrence despite appropriate therapy, and diminished intestinal sounds—should prompt immediate imaging to guide surgical decision-making. The authors highlight that serum biomarkers show promise as additional diagnostic aids, though their specific utility remains an evolving area of investigation. For practitioners managing equine emergencies, this synthesis underscores that implementing systematic abdominal ultrasound examination substantially improves diagnostic accuracy and prognostic outcomes, particularly for the life-threatening strangulating colic cases where surgical intervention within a narrow timeframe is critical for survival.

Practical Takeaways
- •Use abdominal ultrasound as a primary diagnostic tool when evaluating equine colic—it reliably identifies which cases need surgery versus medical management
- •Watch for moderate-to-severe pain signs, recurring pain after initial treatment, and loss of gut sounds as red flags indicating surgical colic requiring emergency referral
- •Recognize that late diagnosis significantly reduces recovery outcomes; implement diagnostic imaging early in colic evaluation to improve prognosis
Key Findings
- •Abdominal ultrasonography is highly effective for diagnosing small intestinal strangulation and distinguishing medical from surgical colic cases
- •Key diagnostic indicators for surgical intervention necessity include moderate to severe pain, pain recurrence after therapy, and diminished intestinal sounds
- •Ultrasound can effectively verify equines with flatulent, spasmodic, obstructive, impactive, strangulating colic, peritonitis, hernias, cystitis, urine retention, and abdominal abscesses
- •Serum biomarkers show potential as diagnostic aids for acute abdominal pain in equines
