What This Study Found
A Dutch retrospective study examined whether routine contrast enema before stoma reversal actually identifies clinically significant strictures 0:00. Among 244 children under three years old who underwent stoma reversal, 10% developed strictures 0:00 0:00 0:00. The striking finding: 95% of those strictures occurred in patients whose original indication was necrotizing enterocolitis 0:00.
Of the total cohort, 68% received contrast enema before reversal 0:00. When performed, the study detected 92% of strictures 0:00. The implication is clear: contrast enema appears most useful as a pre-reversal screen specifically in the NEC population, where stricture risk concentrates 0:00.
What This Means for Practice
For patients who received ostomies for other indications — meconium ileus, Hirschsprung disease, anorectal malformations, intestinal atresia — the stricture rate in this cohort was low enough to question routine imaging. The 92% detection rate matters only if the baseline risk justifies screening 0:00.
The study does not address what happens when you skip the enema in non-NEC patients. It tells you that strictures are rare in that group, and that when you do image everyone, you catch most of what's there. It does not tell you whether finding those strictures preoperatively changes outcomes, or whether intraoperative assessment would suffice.
What Remains Uncertain
This is observational data from a single center over two decades 0:00. Practice patterns for NEC management, stoma creation timing, and reversal criteria likely evolved during that span. The study does not stratify by NEC severity, length of defunctionalized bowel, or time to reversal — all factors that might refine risk prediction further.
The strictures missed by contrast enema were presumably identified at operation or postoperatively, but the study does not detail those cases or their outcomes 0:00.
The Practical Question
If you are reversing an ostomy in a child whose indication was NEC, this study supports obtaining a contrast enema. If the indication was something else, the yield appears low, though the study does not provide a head-to-head comparison of outcomes with and without imaging in that subgroup.
Takeaways from this story
- 95% of strictures after stoma creation occurred in NEC patients, suggesting selective rather than universal pre-reversal imaging.
- Contrast enema detected 92% of strictures when performed, supporting its use in the high-risk NEC population.
- Only 10% of all patients developed strictures, with concentration in NEC cases raising questions about routine imaging in other diagnoses.
