Sa1981 Pre-Operative Nutritional Status and Immunosuppression as Predictors of Post-Operative Events in Pediatric Ulcerative Colitis Patients

days) post-operative events occurred in two patients with recurrent perianal disease. Both had normal BMI: one was on IM and one on biologics peri-operatively. Long-term (30-180 days) post-operative events included repeat surgery (1/13, on steroids/biologics), and rectal bleeding requiring readmission (1/13, on biologis); both had normal BMI. One patient had an anastomotic stricture requiring repeat surgery, however this was at >2 years. Of note, 9/ 13 (69%) were seen by our practice as a second opinion. Conclusions: Immunosuppression is more common than malnutrition in pediatric patients with Crohn's disease who have post-operative events.
