Summary
# Cecal Impaction Management: Comparative Outcomes from 20 Years of Cases Medical records from 150 horses with cecal impaction (1991–2011) were reviewed to compare survival rates following conservative treatment versus two surgical approaches: typhlotomy alone or jejunocolostomy. Two-thirds of cases had preceding illness or surgery as a risk factor, and notably, 25% already had cecal perforation at admission. Horses undergoing surgery showed significantly better short-term survival (82%) compared to those managed medically (61%), yet long-term prognosis at one year was more modest across all groups (57% for medical, 73% for typhlotomy, 70% for jejunocolostomy), with no meaningful difference between the two surgical techniques. The finding that surgical intervention improves discharge survival warrants earlier consideration of typhlotomy or jejunocolostomy in cases not responding to aggressive medical management, particularly given that both surgical approaches yielded equivalent long-term outcomes and the substantial proportion of patients presenting with pre-existing complications. These results suggest that prognostic counselling for cecal impaction should distinguish between immediate post-treatment survival and realistic long-term expectations, whilst recognising that individual horse factors and case complexity substantially influence these population-level statistics.

Practical Takeaways
- •Early surgical intervention offers significantly better short-term survival (82% vs 61%) compared to medical management alone in cecal impaction cases
- •Choice between typhlotomy and jejunocolostomy shows equivalent long-term outcomes (70-73% at 1 year), so surgical approach can be tailored to individual case anatomy and surgeon preference
- •Identify and manage preceding causes (recent illness or surgery) in 68% of cecal impaction cases, as this may be a preventable risk factor
Key Findings
- •68% of horses with cecal impaction had a history of recent disease or surgical procedure preceding the impaction
- •Surgical management (typhlotomy or jejunocolostomy) resulted in 82% survival to discharge compared to 61% for medical management (P=0.02)
- •At 1-year follow-up, 73% of horses managed with typhlotomy and 70% with jejunocolostomy survived, with no significant difference between surgical approaches (P=0.86)
- •25% of horses presented with cecal perforation at admission, representing advanced disease
