title: Predicting hollow visceral injury in the pediatric blunt trauma patient with solid visceral injury.
abstract: BACKGROUND
  Nonoperative management of a solid organ injury (SVI) is accepted in the stable pediatric trauma patient. A concern with nonoperative management is missing a hollow visceral injury (HVI). Factors that may help predict HVI have not been well documented.
  
  
  METHODS
  The National Pediatric Trauma Registry was reviewed for the period October 1988 through September 1998 for all blunt injured, hemodynamically stable pediatric patients (age < or =12 years) with an SVI (kidney, liver, pancreas, spleen) of Abbreviated Injury Scale (AIS) score > or =2. HVIs included AIS > or =2 gastrointestinal tract injuries.
  
  
  RESULTS
  For the decade of review, 2,977 pediatric patients sustained an SVI, including 96 with an HVI (3.2%). The mean age was 6.6 years, with a mean Injury Severity Score of 12.4. An occupant in a motor vehicle accident was the most common injury mechanism (30.4%), but assault was the most likely to result in an HVI (11.5%). The liver was the most common SVI (n = 1,400), the spleen the least likely to have an associated HVI (2.5%). Pancreatic injuries had a higher rate of HVI (P < .001). The majority of patients had a single SVI (n = 2,507) with 71 associated HVIs (2.8%). The risk of associated HVI increased as the number of solid organs injured increased: 4.7% with 2 organs, 13.5% if 3 organs were injured (P< .001). In patients with a single SVI, the rate of HVI did not differ as AIS increased (range, 2.7% to 6.5%, Pvalue not significant).
  
  
  CONCLUSIONS
  The overall rate of HVI was low (3.2%). Higher rates of HVI were found in assaulted patients and patients with multiple SVIs or pancreatic injuries. The risk of associated HVI was dependent more on number of SVIs than severity of the individual organ injury. This data suggest that nonoperative management is justified in the patient with a single SVI but should be used cautiously in the patient with multiple SVI or a pancreatic injury.
