Summary
# Editorial Summary: Nephrosplenic Space Closure and Recurrent Colic Left dorsal displacement of the left colon (LDDLC) is a frustratingly common cause of recurrent colic, and nephrosplenic space closure has become a standard preventive approach—yet robust evidence supporting its efficacy has been limited. A retrospective analysis of 156 horses treated for LDDLC at the University of Liège between 2004 and 2016 examined whether preventive surgical closure of the nephrosplenic space reduced colic recurrence rates, with follow-up data gathered via telephone interview over a mean period of 35 months. Horses that underwent nephrosplenic space closure showed a statistically significant reduction in total colic incidence compared with those managed medically alone, with zero cases of recurrent LDDLC documented in the surgically treated group. For practitioners managing horses with a history of LDDLC, these findings provide meaningful support for recommending preventive nephrosplenic space closure as a strategy to substantially decrease the likelihood of recurrent episodes, though individual case selection and owner circumstances should guide the surgical decision.

Practical Takeaways
- •Prophylactic nephrosplenic space closure effectively prevents recurrent LDDLC and reduces overall colic incidence in affected horses
- •Horses treated medically for LDDLC without surgical closure have significantly higher colic recurrence rates and warrant consideration for preventive surgery
- •This procedure should be discussed with owners of horses presenting with LDDLC as a strategy to improve long-term outcomes and reduce future colic episodes
Key Findings
- •Nephrosplenic space closure resulted in significant decrease in total incidence of colic compared to non-operated horses
- •No horse developed LDDLC recurrence after nephrosplenic space closure surgery
- •Follow-up data available for 65% of cohort with mean follow-up of 35 months
