Adult splenic injuries: treatment patterns and predictive indicators.
BACKGROUND
With the trend towards conservation in splenic trauma, the ability to identify a group of patients for whom we can safely offer conservative treatment becomes an important factor.


METHODS
Data were reviewed from the trauma register at the Auckland Hospital, Auckland, New Zealand, in an attempt to isolate any predictive factors that may allow more appropriate allocation of treatment modalities in the future. Methods of treatment were determined and the success or failure of conservative management noted. Differences in the demographics, Injury Severity Score (ISS) and computed tomographic (CT) findings were particularly sought.


RESULTS
Over a period of 111 weeks 48 patients were admitted with splenic injuries. Fifteen (31.2%) had immediate splenectomy, 27 (56.2%) were initially treated non-operatively and six (10.1%) died pre-operatively. Of the non-operative group eight (29.6%) failed this management at an average of 4.125 days into their hospital stay. No differences were found in age, mechanism, gender or ISS between the failed and successfully treated group. Using the Buntain classification of CT-graded splenic injury, 13 (87%) who had successful non-operative treatment had a grade II or III compared with six (86%) who failed this management being grade IV.


CONCLUSIONS
Although these results did not reach statistical significance, by coupling the trends seen together with other work, CT grading of splenic injury is a predictive indicator and does appear to have a role in the early allocation of patients to appropriate treatment plans.
