Blunt liver trauma is one of the most common injuries in abdominal trauma, with severity classified using the American Association for the Surgery of Trauma (AAST) grading system. Advances in imaging and interventional radiology have shifted management paradigms toward non-operative management (NOM) for hemodynamically stable patients. However, the optimal approach for patients with Grade IV liver injuries remains debated. While lower-grade injuries are well supported for NOM, and higher grades (e.g., Grade V) often require operative management (OM), Grade IV injuries fall in a grey zone where both strategies are employed depending on resources, hemodynamic status, and associated injuries. There is a need to synthesize and map current evidence on outcomes, selection criteria, and clinical decision-making for NOM versus OM in Grade IV blunt liver trauma. This scoping review aims to identify knowledge gaps and provide an overview of existing literature to guide future research.
