Conservative treatment shows favorable outcomes in five children with traumatic duodenal intramural hematoma

This retrospective cohort study analyzed five children with traumatic duodenal intramural hematoma. All patients received conservative treatment consisting of gastrointestinal decompression and intravenous nutrition. The study did not include a comparator group, and key details such as setting, primary outcome, and follow-up duration were not reported.

Initial CT imaging in all five children showed characteristic findings including the 'ice melting sign' and 'fissure sign' with no lesion enhancement. Two children underwent follow-up MRI, which revealed specific signal characteristics and no enhancement. All five patients underwent multiple dynamic ultrasound follow-up examinations, which clearly displayed intestinal wall structure, hematoma absorption, and degree of intestinal obstruction.

The authors reported that conservative treatment resulted in favorable outcomes, and that initial CT diagnosis combined with multiple ultrasound follow-up had high specificity for diagnosis and treatment. No safety or tolerability data were reported. The study had significant limitations including its retrospective design, very small sample size (n=5), lack of control group, and absence of statistical analysis or comparative data.

For clinical practice, this study provides preliminary descriptive evidence from a tiny cohort suggesting that conservative management with imaging follow-up may be effective for pediatric traumatic duodenal intramural hematoma. However, the evidence is insufficient to guide practice without confirmation from larger, prospective studies.
