A new technique of heterotopic autotransplantation of pieces of the spleen is suggested. It differs from the methods used previously in that the pieces of the autologous transplant are placed between the layers of the greater omentum and not on its surface. Not only was the viability of the pieces of the autologous transplant maintained but the hazard of intraabdominal adhesions and their unfavourable consequences was reduced to a great measure.
