Summary
# Exploratory Celiotomy in Equine Acute Colic: Indications and Outcomes Surgical exploration of the abdomen remains a critical intervention for horses with acute colic unresponsive to medical management, yet owner anxiety about outcomes often stems from outdated or inaccurate survival expectations. This review synthesised evidence from tertiary referral hospital records and peer-reviewed literature to establish clear preoperative indicators for surgical necessity and realistic prognostic data for practitioners advising clients on referral decisions. Multiple clinical parameters available to field vets—including rectal examination findings, nasogastric reflux volumes, and peritoneal fluid characteristics—demonstrate high predictive value for identifying cases requiring celiotomy, potentially streamlining decision-making and reducing delays. Survival rates vary considerably by underlying pathology but span 60–100%, with return to athletic function achievable in 76–90% of surviving horses, figures substantially more optimistic than commonly assumed. As primary veterinarians are the crucial information source guiding owners toward surgical referral, understanding both indications for exploration and evidence-based prognosis is essential for facilitating informed consent and improving outcomes in horses with surgical colic.

Practical Takeaways
- •Use available field diagnostic parameters (clinical signs, physical examination findings) to make evidence-based decisions about surgical referral rather than assuming poor prognosis — actual survival rates are 60-100% depending on lesion type
- •Educate horse owners that return to athletic function after colic surgery is good to excellent (76-90%), as misconceptions about poor outcomes often prevent appropriate treatment decisions
- •Understand that intraoperative findings and underlying lesion type are critical determinants of outcome — guide owner discussions with realistic prognosis based on specific diagnosis when possible
Key Findings
- •Specific clinical preoperative parameters available to field practitioners have high positive predictive value for determining need for surgical intervention in equine acute colic
- •Survival rates following exploratory celiotomy range from 60-100% depending on underlying lesion type
- •Return to athleticism following celiotomy is good to excellent at 76-90%
- •Owner expectations and perception of poor survival rates significantly influence decision-making for surgical referral despite favorable actual outcomes
