Splenic trauma and salvage.

The traditional view of the spleen as an expendable organ is no longer tenable. In recent years the importance of the spleen in immunologic processes of bacterial clearance, phagocytosis, and antibody formation has been well established. Post-splenectomy sepsis, once only considered a threat in children, is now recognized in adults. Several techniques have evolved since the early 1930s in dealing with splenic injury. These techniques include observation, prevention of iatrogenic injury, auto transplantation, and suture repair in conjunction with hemostatic agents. A recent review of splenectomies done at our institution showed a salvage rate of 97 per cent in children and 6.3 per cent in adults. The preservation of splenic function should be the principal goal in the isolated injury to the spleen; especially for iatrogenic trauma, conservative surgical management is indicated, particularly in children, but also now in adults.
