El colon por enema de rutina previo al cierre de ostomía parece ser requerido sólo luego de una enterocolitis necrotizante
Topic overview
Estudio retrospectivo demuestra que las estenosis previas al cierre de ostomía ocurren principalmente en pacientes con enterocolitis necrotizante (95%). El colon por enema mostró excelente precisión diagnóstica (sensibilidad 100%, especificidad 98%) sugiriendo que solo debe realizarse rutinariamente en pacientes con antecedente de NEC.
Key takeaways
- Strictures before ostomy closure occur primarily in NEC patients (95%), not other conditions requiring ostomy creation.
- Contrast enema shows excellent diagnostic accuracy for stricture detection: 100% sensitivity, 98% specificity in pediatric ostomy patients.
- Routine contrast enema may only be necessary in NEC patients, potentially avoiding unnecessary studies in other ostomy indications.
- Undetected strictures can cause obstruction requiring reoperation within 3 months of ostomy closure.
- In NEC cohort, contrast enema detected 92% of strictures with 88% PPV and 100% NPV for surgical findings.
