OBJECTIVE: Postoperative recurrence of Crohn's disease in adults has been extensively studied; however, the course of Crohn's disease after surgery in children has not been well defined. The aim of this study was to examine the postoperative course of pediatric Crohn's disease and the factors that may predict early postoperative recurrence. METHODS: We identified 100 resective surgeries in 79 children with Crohn's disease seen at the Children's Hospital of Philadelphia between 1978 and 1996. A retrospective, multivariable analysis of factors potentially influencing postoperative clinical recurrence was performed. Preoperative and postoperative height measurements were compared, and z scores were computed for height-for-age. Two-tailed t test was used for the analysis. RESULTS: Clinical recurrence rates were 17% at 1 yr, 38% at 3 yr, and 60% at 5 yr. Patients with colonic Crohn's disease had a significantly shorter postoperative recurrence-free interval (median 1.2 yr) than patients with ileocecal (median 4.4 yr) or diffuse disease (median 3.0 yr) (p = 0.01). On multivariable analysis, a high Pediatric Crohn's Disease Activity Index at the time of surgery (p = 0.01) and preoperative use of 6-mercaptopurine (6-MP) (p < 0.005) were also independently associated with higher postoperative recurrence rates. There was a significant improvement in z scores for height (p = 0.04) after surgery. CONCLUSIONS: In children undergoing resective surgery for Crohn's disease, high rates of postoperative Crohn's disease recurrence are associated with severe disease at the time of surgery, colonic Crohn's disease, and the preoperative use of 6-MP. Patients who require preoperative use of 6-MP are likely to suffer from a more aggressive disease and would benefit from postoperative 6-MP prophylaxis. Height growth was improved after intestinal resection for Crohn's disease.
