Summary
# Return to Use Following Colic Surgery: What the Data Show Between 2003 and 2010, researchers at North Carolina State University reviewed 195 horses that had undergone exploratory celiotomy for colic, tracking their return to functional use through telephone interviews and outcome data. At six months post-surgery, 68% of surviving horses had returned to their intended use, though only 54% had matched or exceeded their pre-operative performance levels; by one year, these figures improved to 76% and 66% respectively. Certain factors significantly reduced the likelihood of full recovery: horses with a history of previous abdominal surgery, those confined to stall rest for orthopaedic conditions before colic surgery, those with non-strangulating lesions, and those that subsequently developed incisional herniae, post-operative diarrhoea, or laminitis all showed materially poorer outcomes. The authors conclude that whilst prognosis for return to use is reasonably optimistic overall, practitioners should counsel owners realistically about pre-existing lameness, the importance of structured rehabilitation, and the potential need for corrective procedures such as incisional hernia repair. These findings emphasise that post-operative complications and pre-existing musculoskeletal compromise are key modifiable factors influencing whether a horse will genuinely resume competitive or functional work rather than simply surviving surgery.

Practical Takeaways
- •Counsel owners that approximately 2 in 3 horses will return to work by 6 months and 3 in 4 by one year, but only about half will match preoperative performance levels early on
- •Horses with previous colic surgery, orthopaedic conditions requiring stall rest, or those developing post-operative complications (hernia, diarrhoea, laminitis) have significantly reduced return-to-use prospects and require modified expectations
- •Implement targeted rehabilitation protocols and early intervention for post-operative complications (especially incisional hernioplasty) to optimize functional recovery outcomes
Key Findings
- •At 6 months post-celiotomy, 68% of horses (133/195) returned to intended use and 54% (85/156) reached or exceeded preoperative performance levels
- •By one year, return to use improved to 76% (145/190) with 66% (101/153) at or above preoperative performance
- •Previous celiotomy, stall rest for orthopaedic conditions, nonstrangulating lesion type, incisional hernia, diarrhoea, and laminitis were significant negative prognostic factors
- •Overall prognosis for return to use and performance following colic surgery is fair to good despite multiple risk factors affecting outcomes
