Effectiveness of contrast-enhanced ultrasound in the classification and emergency management of abdominal trauma
To analyse the correlation between contrast-enhanced ultrasound (CEUS)-based classification of the severity of abdominal parenchymal organ trauma and clinical outcomes, and to explore CEUS in classifying patients with such trauma, expecting that the use of CEUS will potentially enhance the quality and speed of the emergency management of abdominal trauma.
Three hundred six consecutive patients with blunt abdominal parenchymal organ trauma who received CEUS examination were retrospectively analysed. Two CEUS radiologists (identified as Reader A and Reader B in this study) who were not involved in the CEUS examinations of the patients were then asked to classify the patients independently according to their CEUS results. The classification results were later compared with patients’ clinical outcomes using Spearman’s rank correlation.
The final clinical outcomes showed that 25.5 % (78/306) of patients received conservative treatment, 52.0 % (159/306) received minimally invasive treatment, and 22.5 % (69/306) received surgery. Spearman's rank correlation coefficients between the CEUS-based classification and clinical outcome were 0.952 from Reader A and 0.960 from Reader B.
CEUS can play an important role in the emergency management of abdominal trauma through the classification of patients for different treatment methods.
• The severity of abdominal trauma was classified by contrast-enhanced ultrasound (CEUS)
• There was a high correlation between CEUS-based classification and clinical outcomes
• CEUS-based classification is helpful for surgeons in the emergency management of abdominal trauma
