Summary
# Ileal Impaction Surgery: Manual Decompression Versus Enterotomy When horses present with surgical ileal impactions, veterinarians must decide between attempting manual decompression or proceeding directly to jejunal enterotomy. This retrospective study of 121 cases across three teaching hospitals compared postoperative outcomes between these two approaches, with manual decompression performed in 88 horses and distal jejunal enterotomy in 33, to determine whether the more conservative technique offered any advantage. Contrary to what might be expected, neither approach showed significant differences in minor or major postoperative complications, postoperative reflux (either presence or volume), or survival to discharge rates. The analysis identified two critical predictors of survival: preoperative packed cell volume (PCV) and surgical duration, suggesting that patient status at presentation and procedural efficiency matter more than operative choice. These findings support an argument for earlier adoption of jejunal enterotomy in cases of moderate to severe impaction—rather than investing operative time in manual decompression attempts that may ultimately delay definitive treatment—particularly in horses presenting with elevated PCV values or where prolonged surgery is anticipated.

Practical Takeaways
- •Manual decompression and jejunal enterotomy carry equivalent complication and survival rates for ileal impaction, allowing surgeon choice based on individual case factors
- •Consider jejunal enterotomy earlier in cases of moderate-to-severe impactions rather than reserving it as a backup procedure, as outcomes are equivalent
- •Monitor pre-operative PCV and minimize surgery duration as these factors significantly influence post-operative survival
Key Findings
- •No significant differences in minor or major postoperative complications between manual decompression (n=88) and jejunal enterotomy (n=33) groups
- •No significant differences in postoperative reflux presence, reflux volume, or survival to discharge between surgical approaches
- •Pre-operative packed cell volume (PCV) and surgery duration were significant predictors of survival to discharge
