Abstract
BackgroundThe objective of this study was to identify factors associated with the use of spleen-conserving surgeries, as well as patient outcomes, on a national scale. MethodsThis retrospective cohort study (2010–2015) included patients (age≥16 years) with splenic injury in the National Trauma Data Bank. Patients who received a total splenectomy or a spleen-conserving surgery were compared for demographics and clinical outcomes. ResultsDuring the study period, 18,425 received a total splenectomy and 1,825 received a spleen-conserving surgery. Total splenectomy was more likely to be performed for patients with age>65 (odds ratio [OR]: 0.63, p < 0.001), systolic blood pressure<90 (OR: 0.63, p < 0.001), heart rate>120 (OR: 0.83, p = 0.007), and high-grade injuries (OR: 0.18, p < 0.001). Penetrating trauma patients were more likely to undergo a spleen-conserving surgery (OR: 3.31, p < 0.001). The use of spleen-conserving surgery was associated with a lower risk of pneumonia (OR: 0.79, p = 0.009) and venous thromboembolism (OR: 0.72, p = 0.006). ConclusionsSpleen-conserving surgeries may be considered for patients with penetrating trauma, age<65, hemodynamic stability, and low-grade injuries. Spleen-conserving surgeries have decreased risk of pneumonia and venous thromboembolism.
