Contrast Challenge Algorithms for Adhesive Small Bowel Obstructions Are Safe in Children: A Multi-Institutional Study

Topic overview

Multi-institutional study of 82 children demonstrates water-soluble contrast challenges are safe (0% complication rate) and highly predictive for managing adhesive small bowel obstructions non-operatively. The contrast challenge showed 100% sensitivity and 86% specificity in identifying which patients require surgery versus conservative management.

Key takeaways

Water-soluble contrast challenge in pediatric ASBO has zero complications (0%, 95% CI: 0-3.6%) across 5 institutions, meeting safety threshold.
Contrast challenge predicts surgical need with 100% sensitivity and 100% NPV—no child passed contrast and still required surgery.
65% of children with ASBO were successfully managed nonoperatively when contrast challenge was incorporated into the algorithm.
Contrast challenge specificity of 86% and PPV of 93% reliably identifies which children can avoid surgery for adhesive SBO.
