Pediatric abdominal trauma: evaluation by computed tomography.
When indications for immediate laparotomy are not present, CT of the abdomen and pelvis can be used to evaluate pediatric blunt abdominal trauma. During 2-year period, the medical records and abdominal/pelvic CT scans of 100 consecutive pediatric patients who were evaluated for blunt abdominal trauma were retrospectively reviewed. The scans appeared normal for 73 children. Of these children, 30 had severe head injuries and a depressed sensorium. A total of 27 abdominal/pelvic CT scans were interpreted as abnormal. Findings included nine splenic fractures, six renal contusions, nine hepatic lacerations, one duodenal hematoma, one traumatic pancreatitis, four bony injuries, six miscellaneous abnormalities, and one intraperitoneal bleed. Only two of these 27 patients required abdominal surgery. The remaining 25 patients were treated conservatively based upon a stable clinical state and CT delineation of the extent of injury. No mortality resulted. CT is the radiographic examination of choice for hemodynamically stable pediatric patients with blunt abdominal trauma. CT provided a reliable adjunct examination technique when a physical examination could not be performed and a complete history could not be obtained. The extent of abdominal/pelvic injuries is well delineated and can often be followed by diagnostic imaging, usually allowing for conservative therapy.
