In the assessment of blunt abdominal trauma, the reliability of ultrasonography (US) in identifying individual organ injuries remains uncertain, in spite of its usefulness in detecting hemoperitoneum. This study was designed to evaluate the overall diagnostic value of US, including identification of individual organ injuries.
The accuracy of US in the detection of intra-abdominal injuries and the identification of individual organ injuries was evaluated in 1,239 patients seen during a 15-year period. Accuracy was based on detection of intraperitoneal fluid, free air, or irregular parenchymal lesions.
For the detection of injuries, US was 94.6% sensitive, 95.1% specific, and 94.9% accurate. Individual organ injuries were identified with sensitivities of 92.4, 90.0, 92.2, 71.4, and 34.7% for the liver, spleen, kidneys, pancreas, and intestine, respectively.
US is reliable for the detection of injuries and the identification of solid-organ injuries despite its poor sensitivity for intestinal injuries.
在钝性腹部创伤评估中，尽管超声检查（US）在检测腹腔积血方面有用，但在识别单个器官损伤方面的可靠性仍不确定。本研究旨在评估US的总体诊断价值，包括识别单个器官损伤。
在15年期间对1239例患者进行评估，以确定US检测腹腔内损伤及识别单个器官损伤的准确性。准确性基于腹腔内液体、游离气体或实质脏器不规则病变的检测。
对于损伤的检测，US的敏感性为94.6%，特异性为95.1%，准确性为94.9%。肝、脾、肾、胰腺和肠道单个器官损伤的识别敏感性分别为92.4%、90.0%、92.2%、71.4%和34.7%。
尽管US对肠道损伤的敏感性较差，但在检测损伤和识别实性器官损伤方面是可靠的。
