Nonoperative Treatment of Adult Splenic Trauma

Abstract

We reviewed the charts of 87 patients with documented splenic injuries resulting from blunt trauma admitted to a regional trauma referral center during the 32-month period beginning in January 1984. Delayed celiotomy was defined as surgical intervention for splenic injury after a trial of nonoperative management lasting at least 24 hours. Delayed celiotomy was not required in any of the 16 cases in the pediatric age group (age .ltoreq. 17 years) who were initially managed nonoperatively. In contrast, of the 27 adults who were initially treated nonoperatively, ten (37%) ultimately required celiotomy. Although splenorrhaphy was successfully performed in 21 of 44 patients undergoing early operation, all ten of the patients requiring celiotomy after an unsuccessful trial of observation underwent splenectomy rather than a spleen-preserving procedure. Of the 27 adults who were initially managed nonoperatively, 24 had abdominal computed tomography (CT) performed during their initial diagnostic evaluation. Twenty-three of these scans were reviewed by one of the authors. A CT scoring system was developed, based on the degree of splenic parenchymal and capsular injury and the amount of fluid in the abdomen and the pelvis. Adult patients who were successfully treated without operation had a significantly (p = 0.011) lower total CT score than did patients who required delayed celiotomy. No adult with a total CT score less than 2.5 required delayed operative intervention. These data support the idea that "conservative" management of splenic trauma is safer in children than adults; nevertheless, CT can be used to select a subset of adults with splenic trauma who are excellent candidates for a trial of nonoperative management.
