Results/Discussion: A total of 999 colonoscopies were included in the audit. The main indication for colonoscopy was for a new diagnosis of Inflammatory Bowel Disease (IBD) 45%, followed by bright per rectum (PR) bleeding 20% and IBD restaging 15%. The most common diagnosis was a normal diagnosis which accounted for 41%, followed by Crohn’s 25% and Ulcerative Colitis 14%. There were 200 colonoscopies performed for bright PR bleeding. Of these, there were 94 (47%) normal colonoscopies, 46 (23%) anal fissures, 39 (20%) Juvenile Polyps, 11 (6%) miscellaneous findings, 8 (4%) IBD, 1 (0.5%)

FAP and 1 (0.5%) aborted procedure. Thus, SCH727965 almost half of the colonoscopies performed for PR bleeding were normal and moreover, another quarter had anal fissures. These two groups learn more with normal colons accounted for 140 (70%) of colonoscopies indicated for PR bleeding. Conclusion: When a colonoscopy is performed for a suspected diagnosis of IBD, there will always be a proportion of patients who have a normal colonoscopy and attempting to reduce these numbers is clearly quite complex. We have therefore focused on our second largest indication for pediatric colonoscopy, PR bleeding, to determine if unnecessary colonoscopies could be reduced in view of increased pressure on our endoscopy lists. We found in 140 of 200 (70%) of colonoscopies, the colon was normal. We propose that in the child with PR bleeding

without any other concerning features, a trial of laxatives be given initially before proceeding to a colonoscopy. In the group of children where the PR bleeding resolves completely, a colonoscopy could be avoided.

of inflammatory Bowel diseases (IBD) including Crohn’s Disease (CD) or Ulcerative colitis (UC). Anti saccharomyces cerevisiae antibody (ASCA) is detected in 50- 60% of CD patients and peri nuclear cytoplasmic antibody (pANCA) in 60% to 80 % of UC patients. Studies in adults have suggested that ASCA could also be an indicator of future severe disease, however there is a paucity of pediatric data. A few studies have evaluated the role of ANCA in relation to disease severity but the results were inconclusive. Aim: The aim of our study was to evaluate the role of ASCA and ANCA in predicting the severity of inflammatory bowel disease in pediatric patients. Method: Paediatric patients who presented to the Royal Children’s Hospital for management of IBD were recruited and ASCA and ANCA status was determined Patients with no evidence of IBD constituted controls.
