The Effect of Splenic Hilum Ligation on the Injured Spleen and Its Function in Rat Model

Abstract

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.
