Background: The treatment for splenic injury is evolving to an increased use of nonoperative management. We studied patients with blunt injury to the spleen to determine the overall success with splenic salvage and the reason that adults and children have different outcomes.
Methods: Patient records were reviewed retrospectively for information and parameters that may influence outcome. Patients were categorized by age and type of management.
Results: Two hundred sixty-seven patients (222 adults; 45 children < 16 years old) with blunt splenic trauma were treated over a 7.5-year period. Adults had a significantly higher injury severity score (ISS; 27.2 +/- 0.9 vs 19.9 +/- 2.0; P < .05), splenic injury score (SIS; 2.8 +/- 0.1 vs 2.3 +/- 0.1; P < .01), and mortality rate (11.7% vs 2.2%; P < .05) compared with children. Eighty-six adults and 3 children had emergent operation; 23 patients had splenorrhaphy. Nonoperative management was selected initially in 178 patients; 83% (105 adults and 42 children) were treated successfully. The ISS and SIS of patients in whom nonoperative management failed were different from those patients in whom treatment was successful (ISS, 27.5 +/- 2.1 vs 20.6 +/- 1.0; SIS, 3.6 +/- 0.2 vs 2.1 +/- 0.1; P < .05) but were similar to those patients who needed initial emergent operation. Adults and children who had successful nonoperative management had similar ISSs (21.4 +/- 1.1 vs 18.4 +/- 2.0) and SISs (2.0 +/- 0.1 vs 2.3 +/- 0.1). Overall splenic salvage was achieved in 64% of patients (57% of adults and 96 % of children). Salvage increased from 50% to 85% during the study period.
Conclusions: Splenic preservation is possible in most adults and children with blunt injury with the appropriate use of both operative salvage and nonoperative treatment. The higher salvage rate and decreased need for operation in children is due to their lower severity of overall injury and splenic injury. Operative salvage has become less common in adults because more patients are selected for nonoperative management.
