Risk factors for stoma and incision complications of enterostomy in children with very early-onset inflammatory bowel disease: a prospective cohort study.

Unlabelled: Enterostomy is utilized to mitigate severe clinical symptoms in children with very early-onset inflammatory bowel disease (VEO-IBD) and to provide a window for stem cell transplantation. Nevertheless, the incidence of postoperative complications is significant, and there is currently a lack of research exploring the risk factors associated with complications related to the stoma and incision following the procedure. The objective of this study is to investigate the risk factors for stoma and incision complications after enterostomy in patients with VEO-IBD. From January 2015 to December 2023, 49 children with VEO-IBD who underwent enterostomy were enrolled in the study. Demographic characteristics, blood biochemical indices, weighted Pediatric Crohn's Disease Activity Index (wPCDAI), and enterostomy-related information were prospectively collected. Multivariate logistic regression was employed to identify the risk factors for ostomy and incision-related complications. All 49 included VEO-IBD children had interleukin-10 (IL-10) signaling defects, with 27 (55.1%) having stomal-related complications and 10 (20.4%) had incision complications after enterostomy. Univariate analysis revealed that wPCDAI (OR, 1.03; 95% CI, 1.00-1.07; P = 0.05) showed a tendency towards statistical significance in the occurrence of ostomy complications. Weight-for-age Z-score (WAZ) (OR, 0.57; 95% CI, 0.39-0.84; P = 0.004), height-for-age Z-score (HAZ) (OR, 0.57; 95% CI, 0.37-0.88; P = 0.01), type of surgery (OR, 0.12; 95% CI, 0.03-0.56, P = 0.007), C-reactive protein (CRP) (OR, 1.02; 95% CI, 1.01-1.04; P = 0.007), and wPCDAI (OR, 1.08; 95% CI, 1.01-1.14; P = 0.009) demonstrated statistical significance in the occurrence of incision complications. However, multivariate binary logistic regression did not reveal any statistically significant factors.

Conclusion: Although emergency surgery is unavoidable, our study suggests that improving nutritional status, reducing CRP levels, and increasing preoperative wPCDAI scores may help reduce post-enterostomy stoma and incision complications in VEO-IBD children with interleukin-10 (IL-10) signaling defects. Further large-scale studies are needed to confirm these findings.

What Is Known: • Enterostomy is commonly used to manage severe symptoms in children with VEO-IBD and to provide a window for stem cell transplantation. • The incidence of postoperative complications, including stoma and incision-related issues, is significant in these patients.

What Is New: • This study identifies potential risk factors for stoma and incision complications following enterostomy in children with VEO-IBD, particularly those with IL-10 signaling defects. • Factors such as nutritional status (WAZ and HAZ), CRP levels, type of surgery, and the wPCDAI were found to be associated with stoma and incision complications in univariate analysis, although multivariate analysis did not show statistical significance for these factors.
