急性阑尾炎超声诊断的图像特征及临床应用价值

Clinical value of ultrasound for diagnosing acute appendicitis : A prospective observational diagnostic study

目的探讨超声诊断急性阑尾炎的临床应用价值。方法对82例急性阑尾炎患者进行超声检查。结果病变阑尾回声及周围的回声特征与病理类型相关。单纯性阑尾炎36例,化脓性阑尾炎23例,坏疽性阑尾炎8例,阑尾周围脓肿8例,漏诊及误诊7例。结论超声诊断急性阑尾炎有便捷、高效、无痛、无创的特点,优势明显,通过超声的声像图特征可以较准确评估病情的严重程度,降低手术风险,大大提高急性阑尾炎的诊断准确率,具有良好的临床应用价值。

Objective To explore the ultrasound diagnosis of acute appendicitis. Methods This study included 82 patients with acute appendicitis who underwent ultrasound examination. Results Echo characteristics of appendix lesions and surroundings associated with their pathological types. Thirty six cases of acute simple appendicitis, 23 cases of acute phlegmonous appendicitis, 8 cases of acute gangrenous appendicitis, 8 cases of appendieeal abscess were diagnosed, and 7 cases were misdiagnosed or missed. Conclusion Ultrasound is a convenient, noninvasive and economical method of diagnose acute appendicitis. Ultrasound can reduce the misdiagnosis rate, evaluate severity, prompt surgical indications, improve the diagnosis of acute appendicitis, and provide diagnostic and surgical basis for acute appendicitis.
