Nonoperative management of adult splenic injury due to blunt trauma: a warning.

An analysis of 11 patients with splenic injury initially receiving nonoperative treatment revealed that 73 percent subsequently required surgery for delayed hemorrhage. The influence of age and the anatomic differences between the adult's spleen and child's spleen may account for the increased incidence of delayed bleeding seen in this series. Which patients might avoid surgical intervention cannot be predicted with certainty from the mechanism of injury or the lack of early physical signs and symptoms. The corresponding medical problems that often exist with the older patient may make nonoperative management, with the inherent risk of hypotension and large transfusion requirements, inappropriate. Although not advocating immediate splenectomy, we encourage early operative intervention with splenorrhaphy. Although improved diagnostic techniques will uncover a greater incidence of splenic injury, the inability to identify the nonoperative patient remains a clinical dilemma. The true role of nonoperative management of splenic injuries in the adult and the criteria for selection need to be further defined with larger prospective series. Although this approach may be useful for some patients, its application cannot be universal, and one must be willing to accept the consequences of delayed hemorrhage.
