Trends in Pediatric Intestinal Failure: A Multicenter, Multinational Study.

Objectives: To assess the natural history and outcomes of children with intestinal failure in a large, multicenter, geographically diverse contemporary cohort (2010-2015) from 6 pediatric intestinal failure programs.
Study Design: Retrospective analysis of a multicenter intestinal failure cohort (n = 443). Competing-risk analysis was used to obtain cumulative incidence rates for the primary outcome (enteral autonomy, transplantation, or death). The χ ² test and Cox proportional hazard regression were used for bivariate and multivariable analyses.
Results: The study cohort comprised 443 patients (61.2% male). Primary etiologies included short bowel syndrome (SBS), 84.9%; dysmotility disorder, 7.2%; and mucosal enteropathy, 7.9%. Cumulative incidences for enteral autonomy, transplantation, and death at 6 years of follow-up were 53.0%, 16.7%, and 10.5%, respectively. Enteral autonomy was associated with SBS, ≥50% of small bowel length, presence of an ileocecal valve (ICV), absence of portal hypertension, and follow-up in a non-high-volume transplantation center. The composite outcome of transplantation/death was associated with persistent advanced cholestasis and hypoalbuminemia; age <1 year at diagnosis, ICV, and intact colon were protective.
Conclusions: The rates of death and transplantation in children with intestinal failure have decreased; however, the number of children achieving enteral autonomy has not changed significantly, and a larger proportion of patients remain parenteral nutrition dependent. New strategies to achieve enteral autonomy are needed to improve patient outcomes.
