Traumas of the spleen in overwhelming majority of patients are followed by destruction of the organ which results in 86% of absolute indications for forced splenectomy. Organ-preserving operations in patients with the injured spleen should be welcome. However their real possibilities can be realized in 8% of the victims only. Immediate outcomes of the surgery are dependent not on its volume on the injured spleen, but on the character and severity of the trauma. Removal of the spleen from the organism of adults due to its trauma is followed only by transitory disturbances of the cellular composition of the peripheral blood, defects of the immune competent system and disturbances of hemostatic properties of blood. In remote terms no higher susceptibility of infection was found.
