This letter argues for the continued relevance of DPL as the most sensitive invasive method for detecting intraperitoneal bleeding, particularly in hemodynamically unstable patients where Focused Assessment with Sonography for Trauma (FAST) and Computed Tomography (CT) scanning are not feasible. Despite technological advances, the unique diagnostic capabilities of DPL warrant its preservation in emergency trauma protocols.
