Postendoscopic duodenal hematoma in children: ultrasound diagnosis and follow-up

Intramural duodenal hematomas have most frequently been reported in children in a traumatic setting. We present two cases of duodenal hematoma that occurred after upper gastrointestinal tract endoscopy with biopsy in children without significant prior medical history. The diagnosis was made by ultrasound, in correlation with the clinical presentation. Because the patients were hemodynamically stable, they were treated conservatively and the regression of the hematoma was followed up with ultrasound until its complete resolution. These cases demonstrate the risks of endoscopy, which are not to be neglected even in children without impaired coagulation, and the manner in which ultrasound can provide the correct diagnosis and follow-up.
