Removal of the spleen accompanied by the development of septic complications and coagulation, formation of postsplenectomy syndrome (PDS). For the prevention of PDS, now widely used method of autologous transplantation of spleen tissue (ATTC) in the greater omentum, the advantage of which is the technical simplicity, high physiological operation, reliable hemostasis. Currently dinny algorithm ATTC has not yet been developed. Therefore, the study of the process of engraftment autografts (AT) under the influence of various factors requires a method of dynamic monitoring in the immediate and late postoperative periods. Objective: To provide a method for diagnosis of splenic engraftment AT transplanted into the greater omentum in the experiment. Method BIM autograft spleen and omentum, is objective, reliable, easy to perform, minimally invasive and allows you to diagnose it engraftment. This method can be widely used in experimental surgery to study the dynamics of the process of engraftment transplantatov.V experiment on rats was studied tissue impedance greater omentum and spleen autografts in the immediate postoperative period. Based on the data developed two methods of diagnosis engraftment autografts spleen in the greater omentum.
