The decision to pursue emergency colic surgery involves complex welfare assessments balancing the suffering of untreated colic against the risks and recovery welfare costs of surgery.
Colic surgery decisions involve genuine and complex welfare trade-offs. Untreated surgical colic causes progressive, extreme pain leading to death - this suffering is unacceptable. Emergency surgery carries risks including anesthetic death, intestinal damage, and post-operative complications including laminitis and adhesion formation. Recovery involves months of restricted activity and box rest. The welfare case for surgery is strongest when the lesion type has a good prognosis and the horse is presented early. When surgery is declined for financial or prognostic reasons, immediate humane euthanasia is the welfare-protective alternative to prolonged suffering from untreated surgical colic.
