  • Inflammatory bowel disease (IBD) is an idiopathic disease that causes intestinal inflammation and lesions. Canada has one of the highest rates of IBD in the world. One of the major types of IBD is Crohn’s Disease (CD) and a large portion of CD patients will undergo surgical resection in the course of their disease. However, up to 90% of these patients will have endoscopic recurrence by 5 years post-surgery. The cause of the recurrence is unknown, but is thought to follow the same course as the initial onset of Crohn’s lesions. In this study CD patients in endoscopic remission and relapse that have undergone ileocolonic resection were compared. Results show there were specific changes in gut microbial composition, variations in urinary metabolites and unique environmental exposures, both current and childhood, between the remission and relapse patients.
