Strategies in liver Trauma

The management of pediatric liver trauma has evolved significantly over the last few decades. While surgical intervention was frequently and mostly unsuccessfully practiced during the first half of the last century, the 1960s were witness to the birth and gradual acceptance of non-operative management of these injuries. In 2000, the American Pediatric Surgical Association (APSA) Trauma Committee disseminated evidenced-based guidelines to help guide the non-operative management of pediatric blunt solid organ injury. The guidelines significantly contributed to conformity in the management of these patients. Since then, a number of well-designed studies have questioned the strict categorization of these injuries and have led to a renewed reliance on clinical signs of the patient's hemodynamic status. In 2019, APSA introduced an updated set of guidelines emphasizing the use of physiologic status rather than radiologic grade as a driver of clinical decision making for these injuries. This review will focus on liver injuries, in particular blunt injury, as this mechanism is by far the most commonly seen in children. Procedures required when non-operative management fails will be detailed, including surgery, angioembolization, and less commonly employed interventions. Finally, the updated inpatient and post-discharge aspects of care will be reviewed, including hemoglobin monitoring, bedrest, length of hospital stay, and activity restriction.
