Objective: To determine the rate and risk factors of failure of non-operative management (NOM) in grade IV and V blunt splenic injuries.
Design: Retrospective case series.
Setting: 14 New England trauma centers.
Patients: 389 adult blunt trauma patients with an American Association for the Surgery of Trauma (AAST) grade of IV or V splenic injury on computed tomography (1/1/01 to 8/31/08). Patients who had incomplete data (48), no CT (72), or arrived dead (3) were excluded.
Main outcome measures: Failure of NOM (f-NOM).
Results: 164 (42%) patients were operated on immediately. Of the remaining 225 who were offered a trial of NOM, 92 (41%) eventually required an operation. Overall 66% of the patients underwent a splenectomy. Multiple logistic regression identified 2 predictors of f-NOM that achieved and 2 that approached statistical significance:
|Predictor||Odds Ratio||95% Confidence Interval||p-value|
|Male gender||2.31||1.23 - 4.36||0.009|
|Grade V (vs. grade IV)||2.93||1.24 - 6.95||0.014|
|Assault (vs. MCV or fall)||4.07||0.91 - 18.26||0.067|
|Age > 55 years||1.92||0.91 - 4.05||0.085|
The likelihood of f-NOM was 100% if all predictors were present but remained 29% even when all predictors were absent. Of f-NOM patients 63% developed a complication and 6.5% died. Their average length of hospital stay was 18+
28 days (median: 8).Conclusions:
Two thirds of patients with grade IV/V blunt splenic injury require an operation. Among those who are initially treated by NOM, the presence of certain simple clinical factors predicts failure with a likelihood of 100%. This data must be taken into account when generalizations are made about the overall high success rates of NOM, which usually do not reflect severe splenic injuries.
