ABSTRACT: Background
It is critical to accurately identify patients with abdominal injury who truly need to undergo laparotomy during the war in timely fashion. The diagnostic utility of computed tomography (CT) for evaluating abdominal injury in the military setting remains uncertain.Methods
PubMed, EMBASE, and Cochrane Library databases were searched. Meta-analyses were performed by using a random-effect model. We pooled the area under the summary receiver operating characteristic curves with standard errors, the Q indexes with standard errors, the sensitivities with 95% confidence intervals (CIs), the specificities with 95% CIs, the positive likelihood ratios with 95% CIs, the negative likelihood ratios with 95% CIs, and the diagnostic odds ratios with 95% CIs. The heterogeneity among studies were evaluated by the I2 and P value.Results
Overall, 5 retrospective studies were included. The area under the summary receiver operating characteristic curve was 0.9761 ± 0.0215 and the Q index was 0.9302 ± 0.0378. The pooled sensitivity was 0.97 (95% CI = 0.92-0.99) without a significant heterogeneity among studies (I2 = 0%, P = .4538). The pooled specificity was 0.95 (95% CI = 0.93-0.97) with a significant heterogeneity among studies (I2 = 90.6%, P < .0001). The pooled positive likelihood ratio was 10.71 (95% CI: 2.91-39.43) with a significant heterogeneity among studies (I2 = 89.2%, P < .0001). The pooled negative likelihood ratio was 0.07 (95% CI = 0.02-0.27) with a significant heterogeneity among studies (I2 = 57.5%, P = .0516). The pooled diagnostic odds ratio was 177.48 (95% CI = 18.09-1741.31) with a significant heterogeneity among studies (I2 = 75.9%, P = .0023).Conclusion
Diagnostic accuracy of CT for abdominal injury is excellent in the military setting. Further work should explore how to shrink CT equipment for a wider use in wartime.
