Duodenal and rectal hematomas complicating endoscopic biopsy: use of sonography in pediatrics.

Objective: Intramural duodenal hematomas (IDHs) after nontherapeutic endoscopic biopsy are rare. Rectal hematomas (RHs) have not been reported previously. A review of the literature revealed 18 cases of IDHs.

Methods: We reviewed 3 cases that occurred within a 4-month period at our institution.

Results: We report a series of 3 cases occurring within a 4-month period. In addition, we report a concurrent RH in 1 of these cases. After becoming symptomatic, 2 of these patients had a diagnosis by computed tomography, the third by sonography. All patients had conservative management and were followed with sonography.

Conclusions: Sonography was found to be an accurate, safe, and nonionizing way to diagnose and follow hematomas in pediatric patients.
