Impact of presence, level and closure of a stoma on growth in young children: A retrospective cohort study

Résumé fourni par la source

Abstract IntroductionA stoma will cause nutrients loss which could result in impaired growth. Impaired growth can negatively impact long-term development. This study aims to evaluate: 1) the effect of stomas on growth comparing small bowel stoma versus colostomy, 2) if early closure (within 6 weeks), proximal small bowel stoma (within 50 centimeters of Treitz), major small bowel resection (≥30 centimeters) or adequate sodium supplementation (urinary level ≤30mmol/L) influence growth. MethodsYoung children (≤3 years) treated with stomas between 1998-2018 were retrospectively identified. Growth was measured with weight-for-age Z-scores. Malnourishment was defined using the WHO-definition. Comparison between changes in Z-scores at closure and a year following closure was done by Friedman-test with post-hoc-Wilcoxon-signed-rank-test or Wilcoxon-rank-sum-test when necessary. ResultsIn the presence of a stoma, 61% showed growth decline. Severe malnourishment was seen at time of stoma closure in 51% of the patients treated by small bowel stoma and 16% of those treated by colostomy. Within a year following stoma closure 67% showed a positive growth trend. Having a proximal small bowel stoma and undergoing major small bowel resection led to significantly lower Z-scores at closure. Adequate sodium supplementation and early closure didn’t lead to significant changes in Z-scores. ConclusionStomas have a negative impact on growth in the majority of children. This impact might be decreased by preventing small bowel stomas, specifically proximal stomas, and limiting small bowel resection. Since stoma closure is essential in reversing the negative effect on growth, we opt that early closure might result in an early shift to catch-up growth.
