目的:探讨和对比超声和多层螺旋CT(MSCT)对可疑急性阑尾炎患者的临床诊断价值。方法:对我院急诊科收治的335例可疑阑尾炎的患者进行超声和MSCT检查,并与手术病理结果对照,比较2种影像学检查技术的临床诊断价值。结果:MSCT诊断急性阑尾炎的敏感性和阴性预测价值明显高于超声检查(98.0%vs.85.2%,93.8%vs.66.4%,P<0.01);MSCT诊断急性阑尾炎阑尾穿孔的敏感性优于超声检查(91.2%vs.67.6%,P<0.05)。超声在检测阑尾增粗肿大和阑尾壁充血增厚的敏感性明显低于MSCT(P<0.01),且在检测阑尾-盲肠周围炎和阑尾周围脓肿时的敏感性和特异性均明显低于MSCT(P<0.01)。结论:多层螺旋CT诊断急性阑尾炎的发生、阑尾穿孔和多种影像学征象的诊断价值明显优于超声检测。
Objective: To investigate and compare the diagnostic value of ultrasound and MSCT in patients with suspected acute appendicitis. Methods: 335 cases of suspicious appendicitis admitted to the emergency department of our hospital were examined by ultrasound and MSCT, and compared with the results of surgery and pathology, the clinical diagnostic value of two imaging techniques was compared. Results: The sensitivity and negative predictive value of MSCT in diagnosis of acute appendicitis were significantly higher than those of ultrasound (98.0% vs 85.2%, 93.8% vs.66.4%, P <0.01). MSCT was superior to ultrasonography in diagnosing appendiceal perforation of acute appendicitis Examination (91.2% vs.67.6%, P <0.05). Sensitivity and specificity of ultrasound in detecting appendiceal enlargement and thickening of the appendix wall were significantly lower than that of MSCT (P <0.01), and the sensitivity and specificity of detecting the appendix - cecum peripancreatitis and appendix abscess were significantly lower than those of MSCT (P <0.01). Conclusion: The diagnosis of acute appendicitis, perforated appendectomy and multiple imaging signs by multislice spiral CT is superior to ultrasonography in diagnosing acute appendicitis.
