Treatment of splenic trauma in Norway: a retrospective cohort study.

BACKGROUND: Non-operative management of splenic injuries has become the treatment of choice in hemodynamically stable patients over the last decades. The aim of the study is to describe the incidence, initial treatment and early outcome of patients with splenic injuries on a national level.

METHODS: All hospitals in Norway admitting trauma patients were invited to participate in the study. The study period was January through December 2013. The hospitals delivered anonymous data on primarily admitted patients with splenic injury.

RESULTS: Three of the four regional trauma centers and 26 of the remaining 33 acute care hospitals delivered data on a total of 151 patients with splenic injury indicating an incidence of 4 splenic injuries per 100,000 inhabitants/year, and a median of 4 splenic injuries per hospital per year. A total of 128 (85%) patients were successfully treated non-operatively including 20 patients who underwent an angiographic procedure. The remaining 23 (15%) patients underwent open splenectomy or spleen-preserving surgery.

CONCLUSION: Most patients with splenic injuries are managed non-operatively. Despite the low number of splenic injuries per hospital, the results indicate satisfactory outcome on a national level.
