Management of Splenic Trauma in Contemporary Clinical Practice: A National Trauma Data Bank Study.

Abstract：

BACKGROUND:To evaluate the utilization and efficacy of various treatments for management of adult patients with splenic trauma, highlighting the evolving role of splenic artery embolization. MATERIALS AND METHODS:The National Trauma Data Bank (NTDB) was queried for patients who sustained splenic trauma between 2007 and 2015, excluding those with death on arrival and selected nonsplenic high-grade injuries. Patients were categorized into (1) nonoperative management (NOM), (2) embolization, (3) splenectomy, (4) splenic repair, and (5) combined treatment groups. Evaluated outcomes included hospital length of stay (LOS), intensive care unit LOS, mortality, and NOM and embolization failures. RESULTS:Overall, 117,743 patients with splenic predominant trauma were included in this study. Over the 9-year study period, 85,793 (72.9%) were treated with NOM, 21,999 (18.9%) with splenectomy, 3895 (3.3%) with embolization, and 2131 (1.8%) with splenic repair. From 2007 to 2015, mortality rates declined from 7.6% to 4.7%. The rate of NOM did not significantly change over time, while embolization increased 369% (1.3%-4.8%). Failure of NOM was 4.4% in 2007 and decreased to 3.4% in 2015. Across all injury grades, NOM had the shortest LOS (8.3 days), followed by splenic repair (12.3), embolization (12.6), and splenectomy (13.8) (p < 0.001). When adjusted for various clinical factors including severity of splenic injury, mortality rates were 7.1% for splenectomy, 3.2% for embolization, and 2.5% for NOM. CONCLUSION:Most patients with splenic-dominant blunt trauma are managed with NOM. Over time, the use of embolization has increased while open surgery has declined, and mortality has improved for all treatment methods. Compared to splenectomy, embolization is associated with shorter hospital LOS but is still used relatively infrequently.
