Spleen transplantation: I. Experimental observations on autotransplantation of splenic tissue into omental pouch

1. Experimental observations on three types of autotransplantation of spleen tissue into omental pouch are reported. Implanted slices and fragments of spleen could preserve certain function. Survival rate of transplants was 100 %. 2. Several factors influencing implant are discussed, such as optimal site for implantation, problem of removal of splenic capsule, volume of transplants, and spleen perfusion. Regenerated slices and fragments seen in a series of exploratory laparotomy and histologic changes are described. 3. We recommend that autotransplantation of splenic slices together with fragments and arrangement of slices in the form of U figure into the omental pouch created by folding be used clinically. The technique is simple, safe and free of complications.
