Fig. 2 ( a ) 10.2 Fr pigtail catheter placed within the duodenal hematoma; ( b ) UGIS 3 days after catheter placement demonstrates the resolution of the duodenal obstruction and dilatation. The large mass shadow, previously seen, has disappeared. Percutaneous drainage is a safe and feasible method of treatment for a very large duodenal hematoma in children and should be considered as an alternative treatment option in similar cases.
