Résumé : This Equine Veterinary Journal supplement on colic is being published in association with the 10th International Equine Colic Research Symposium. The 1st Equine Colic Research Symposium was held at the University of Georgia in 1982, with the goal of creating a forum where clinicians and researchers could present current research on colic, thereby stimulating discussion and generating new ideas and new research. Since the first meeting in 1982, the Symposium has become truly international with BEVA and AAEP alternately hosting the meeting every 34 years. The 10th International Colic Research Symposium is being held in Indianapolis, Indiana, 2628th July 2011, and is being hosted by the AAEP Foundation. Recent symposia have been complemented by supplements or special issues of Equine Veterinary Journal, publishing full peer reviewed articles on colic, many of which are appearing as papers in the Symposium. In this way, the research presented at the meeting is disseminated to the widest international audience.
