This review is intended to highlight findings of recent research and clinical studies that validate use of the JC, and to provide some insights into technical aspects of the procedure that might improve its survival rates. Jejunocecostomy is more complicated than most anastomoses used in the equine small intestine, and a review of its complexities could help to improve outcomes with this anastomosis. The negative attitude towards its use is not supported by recent research and clinical studies. If the ileum has incurred ischemic changes that necessitate its being bypassed, JC is a valid treatment if owner- and disease-related issues support the cost of resection and anastomosis.
