Summary
# Editorial Summary: Age-Dependent Intestinal Repair in Foals with Severe Colic Colic remains the leading cause of equine mortality, with strangulating obstruction causing the most severe outcomes; survival after surgical intervention depends critically on rapid intestinal barrier repair to prevent bacterial translocation and endotoxaemia. Erwin, Blikslager and Ziegler synthesised current evidence on how the enteric nervous system (ENS)—particularly the network of subepithelial enteric glial cells—develops in neonatal foals and how this maturation process influences post-surgical recovery. The authors highlight that postnatal development of the immature glial cell network is driven by early microbial colonisation of the gut, which is itself shaped by dietary factors and the evolving bacterial populations during the foal's first weeks of life. Their review reveals that younger patients paradoxically show poorer clinical outcomes following colic surgery, likely because their intestinal repair mechanisms remain underdeveloped; the gut microbiome, nutrition, stress responses, and ENS function all interact to determine the trajectory of barrier integrity recovery. For equine professionals managing post-surgical colic cases in foals, this work suggests that early-life dietary choices, microbial colonisation patterns, and stress management may have lasting consequences for intestinal resilience, warranting closer attention to nutrition and handling protocols in the neonatal period to support optimal ENS maturation.

Practical Takeaways
- •Neonatal and young foals with colic require particularly close monitoring post-surgery given their age-dependent disparities in intestinal repair capacity and survival outcomes.
- •Early dietary management and microbial colonization patterns in foals may influence the maturation of intestinal repair mechanisms and should be considered in preventive management strategies.
- •Understanding that intestinal barrier repair involves complex interactions between the nervous system, microbiota, and nutrition can inform post-operative supportive care decisions in foal colic cases.
Key Findings
- •Age-related disparities in colic survival exist in horses, with younger patients experiencing poorer clinical outcomes than older animals.
- •The enteric nervous system (ENS) and developing subepithelial enteric glial cells play a critical role in intestinal barrier repair, particularly in neonatal foals.
- •Postnatal development of the enteric glial cell network is driven by microbial colonization of the gut and is modulated by early-life diet-influenced changes in bacterial populations.
- •Intestinal barrier maintenance and repair following surgical colic intervention depends on a complex mucosal microenvironment involving the gut microbiome, nutrition, stress, and the ENS.
