Summary
# Editorial Summary: Equine Gastrointestinal Motility Research Understanding how the equine intestine contracts and propels ingesta remains fundamental to managing colic, post-operative recovery and chronic digestive disease, yet significant gaps persist in our knowledge of conditions such as obstructive disorders and post-operative ileus. Hudson and Merritt reviewed the breadth of research approaches used to investigate intestinal dysmotility—from cellular-level investigations through to in vitro tissue studies and in vivo physiological assessments—that collectively attempt to explain why horses develop abnormal (either reduced or increased) intestinal contractions and impaired digesta flow. The authors identify critical areas where current understanding falls short and map out research priorities needed to translate mechanistic knowledge into improved diagnostic tools, targeted therapeutic interventions and preventative strategies for ileus and other motility-related conditions. For practitioners encountering these cases regularly, the review underscores that management decisions often outpace our actual understanding of underlying pathophysiology, highlighting the clinical importance of continued investigation into how drugs, surgery and nutritional interventions influence motor function. The implications are clear: advances in motility research should directly inform how we assess, treat and monitor horses with functional intestinal problems in both acute and post-operative settings.

Practical Takeaways
- •Motility disorders are a major cause of colic and post-operative complications in horses; understanding their mechanisms will lead to improved clinical management
- •Multiple research approaches (cellular, in vitro, and in vivo) are necessary to fully characterize equine GI dysfunction
- •Future advances in understanding motility pathophysiology should translate to better diagnostic tools and preventive strategies for practicing veterinarians
Key Findings
- •Equine gastrointestinal motility disorders including obstructive disorders and post-operative ileus remain poorly understood despite their clinical significance
- •Research methods to evaluate motility include cellular-level studies, in vitro techniques, and in vivo physiological assessments of ingesta transit
- •Better understanding of intestinal hypo- and hypermotility pathogenesis is needed to improve diagnosis, therapy, and prevention strategies
