Colic surgery decisions involve weighing realistic survival and quality of life expectations against welfare costs of the procedure and recovery in horses with life-threatening conditions.
Colic surgery decisions must integrate the horse's current welfare (severe pain requiring intervention), the welfare costs of surgery and recovery, and the realistic probability of good long-term outcome. For most horses with surgical colic, the alternative to surgery is euthanasia — the question is whether surgery offers a meaningful chance of returning to a good quality of life at acceptable welfare cost. For conditions with high surgical success rates like right dorsal displacement, surgery often offers good welfare outcomes. For conditions with poorer prognosis like extensive small intestinal resection, honest discussion of likely outcomes is essential before proceeding.
