title: Blunt liver injury in children and adults: is there really a difference?
abstract: Hepatic injuries are increasingly managed nonoperatively with the availability of adjunctive procedures such as angiography, ERCP, and percutaneous drainage. Although extensively discussed in the adult population, little has been reported on outcomes and management of pediatric liver injury. Retrospective review of all patients with blunt liver injuries admitted to an adult Level I trauma center and pediatric trauma center within the same community was performed from 2004 to 2006. The necessity for operation, adjuncts to nonoperative management, and outcome were collected and compared for the pediatric (PED) (<18 years of age) versus the adult (> or = 18 years of age) injured patients. There were 389 liver injuries identified (PED = 90, adult = 299); 25 per cent of adult injuries were greater than or equal to grade III, while 23 per cent of PED injuries were high-grade injuries. Each group of patients had similar rates of primary operative intervention: adult patients (18%) versus PED patients (16%). Adjunctive therapies were rarely used in the PED patients with only one patient requiring a percutaneous drain and one patient undergoing ERCP twice. Conversely, the adult patient group required eight percutaneous drains, 15 angiograms, 6 ERCPs and 14 laparoscopic abdominal washout procedures. ICU and hospital LOS were 25 per cent and 33 per cent lower in the adult population for high-grade injuries. The overall mortality rates were similar at 7 per cent (PED) and 9 per cent (adult). Liver-related mortality was 50 per cent (3/6 deaths) in the PED group with no liver-related deaths in the adult group (27 deaths). Adult patients with blunt liver injury were no more likely to sustain high grade liver injuries than PED patients. Furthermore, adult and PED patients underwent similar rates of operative intervention and primary liver procedures. Adult patients used adjunctive measures as part of their nonoperative management more frequently, but both subsets had similar length of hospital stays and low overall mortality. A higher rate of liver-related mortality was seen in the PED population. Overall, PED patients seemed to sustain fewer liver related complications necessitating invasive procedures despite similar injury patterns.
