Significance of Minimal or No Intraperitoneal Fluid Visible on CT Scan Associated with Blunt Liver and Splenic Injuries: A Multicenter Analysis

BACKGROUNDThe use of ultrasound (U/S) for the evaluation of patients with blunt abdominal trauma is gaining increasing acceptance . Patients who would have undergone computed tomographic (CT) scan may now be evaluated solely with U/S. Solid organ injuries with minimal or no free fluid may be missed by surgeon sonographers. OBJECTIVEThe purpose of this study was to describe the incidence and clinical importance of liver and splenic injuries with minimal or no free intraperitoneal fluid visible on CT scan. We hypothesized that these solid organ injuries occur infrequently and are of minor clinical significance. METHODSPatient records and CT scans were reviewed for the presence of and outcome associated with blunt liver and splenic injuries with minimal (
