Management of blunt pediatric hepatic and splenic injury: similar process, different outcome.

Though nonoperative management of stable children with blunt solid organ injury has been shown to be effective, we hypothesize that hepatic injuries represent a higher mortality risk than splenic injuries and that combination hepatosplenic injury is a marker of even greater mortality potential. A multi-institutional pediatric trauma registry was queried for all children with blunt injuries to the liver (H) or spleen (S), excluding those with severe brain injury. Incidence and mortality of H, S, and all combinations of H/S were compared. The mortality rate for patients with H was significantly higher (2.5%) than in patients with S (0.7%), and the overall mortality of H/S (8.6%) was significantly higher than both. Furthermore, the mortality of H/S injuries was associated with increasing severity of either the hepatic or splenic injury. In childhood injury, H and S occur with almost equal frequency but with different mortality, and H/S is less common but associated with increased mortality.
