Background and aims: In children with ulcerative colitis, data on temporal colectomy trends and in-hospital post-colectomy complications are limited. Thus, we evaluated time trends in colectomy rates and post-colectomy complications in children with ulcerative colitis.
Methods: We identified all children (≤18years) with a diagnosis code of ulcerative colitis (ICD-9: 556.X) and a procedure code of colectomy (ICD-9: 45.8 and 45.7) in the Kids' Inpatient Database for 1997, 2000, 2003, 2006 and 2009. The incidence of colectomies for pediatric ulcerative colitis was calculated and Poisson regression analysis was performed to evaluate the change in colectomy rates. In-hospital postoperative complication rates were assessed and predictors for postoperative complications were evaluated using multivariate logistic regression.
Results: The annual colectomy rate in pediatric ulcerative colitis was 0.43 per 100,000person-years, which was stable throughout the study period (P>.05). Postoperative complications were experienced in 25%, with gastrointestinal (13%) and infectious (9.3%) being the most common. Postoperative complication rates increased significantly by an annual rate of 1.1% from 1997 to 2009 (P=.01). However, other independent predictors of postoperative complications were not identified. Patients with postoperative complications had significantly longer median length of stay (14.3days vs 8.2days; P<.001) and higher median hospital charges per patient (US $81,567 vs US $55,461; P<.001) compared to those without complications.
Conclusion: Colectomy rates across the United States in children with ulcerative colitis have remained stable between 1997 and 2009; however, in-hospital postoperative complication rates have increased.
