Background: The aim of this study was to compare the outcome of splenic hilum ligation (SHL) and splenectomy in spleen trauma in rat model. Methods: This interventional study was performed on 38 rats with spleen injuries. Rats were randomly divided into SHL and splenectomy groups. After 7 days of surgery, IgG, IgA, IgM, and IgE were measured. At this time, blood smear was prepared to evaluate Howell–Jolly bodies, target cells, schistocyte, poikilocyte, and anisocyte. Three months after the surgery, the spleen viability was evaluated by relaparotomy. Results: After 7 days, white blood count was significantly lower in SHL group as compared to control group (p  = 0.024). All variables in peripheral blood smear were significantly lower in SHL group as compared to control group, except Howell–Jolly bodies (p  = 0.461). In the SHL group, all spleens were viable in second operations. Conclusions: SHL can be used safely in the management of traumatic splenic injuries in rats.
