Factors related to outcome in blunt intestinal injuries requiring operation.

Associated factors related to outcome following blunt intestinal trauma requiring operative therapy were retrospectively reviewed in all trauma patients admitted to one Level I trauma center. Over 4.5 years, 7598 trauma patients were evaluated, with 62 patients having sustained 92 blunt intestinal injuries requiring operative intervention. Mean age was 34.5 years; mean Injury Severity Score was 22. Mechanism of injury was motor vehicle accident in 50 (81%), with 80 per cent being drivers. Associated intra-abdominal injuries occurred in 46 (74%) patients. Extra-abdominal injuries occurred in 56 patients (90%). Thirty-one patients suffered 82 complications or 2.6 complications per patient (comp/pt). Mortality from operative blunt trauma was associated with admission blood pressure < or = 90 mm Hg (57 vs 13%; P < 0.05), age > or = 24 years (26 vs 0%; P < 0.05), and Injury Severity Score > or = 35 (70 vs 8%; P < 0.05). Morbidity was associated with age > or = 24 years (1.5 vs 0.7 comp/pt; P < 0.05) and delay in operative therapy > or = 24 hours (3.3 vs 1.1 comp/pt; P < 0.05). Overall mortality was 18 per cent.
