Management of adult splenic injury: a 20-year perspective

The objective of this study was to identify changes in the management of blunt splenic injury in adults. Hospital discharge abstract data from Maine were used to identify patients > or = 16 years old discharged between January 1, 1981 and December 31, 2000 with International Classification of Diseases (9th revision) codes indicating splenic injury. Incidence of operative intervention and outcomes for trauma hospitals and other hospitals were determined. The number of splenic injuries was about 75 per year for the first 15 years increasing to 96 per year in the last 5-year period. The rate of operative intervention declined from 71 to 41 per cent and was lower at the trauma hospitals during the last two 5-year periods (41% vs 53%). The rate of operative intervention > 24 hours after admission was 2.2 per cent during the last 10 years of study. The rate of splenorrhaphy remained stable at about 12 per cent throughout the study period. Mortality rates were higher at the trauma hospitals as were the numbers of patients with very severe injuries (Injury Severity Score > 25). There has been a marked decrease in rate of operative intervention for splenic injury in adults especially in the last 10 years. Rates of operative intervention were lower at the trauma hospitals despite higher injury severity. Frequency of delayed intervention was low and did not increase with lower operative rate.
