Sonography in trauma patients can be associated with obstacles as within obese patients or patients with intestinal gas. A retroperitoneal bleeding might be difficult to realize as there is no free fluid seen in the abdomen. Also, small hollow viscus organ lesions can easily be missed. A delay of the diagnose of a hollow viscus organ injury, such as a small bowl injury, has a major impact on the morbidity and mortality of trauma patients.
