摘要：目的：探讨阑尾炎的B超图像特征及其分型。方法：75例经手术及病理证实的阑尾炎，对其B超图像特征进行分析并加以分型。结果：急性阑尾炎B超图像特征均显示阑尾增粗，成人直径大于0.7cm，儿童直径大于0.6 cm，粘膜增粗、中断或缺损，回声明显减弱。根据图像特征将其分为：①单纯性阑尾炎(包括慢性阑尾炎2例)；②化脓性阑尾炎；③坏疽性阑尾炎；④阑尾周围脓肿；⑤急性阑尾炎合并间接征象。结论：B超对阑尾炎的诊断及分型具有重要的临床意义。

    Abstract: Objective: To explore the ultrasonographic characteristics of appendicitis and its classification. Methods: Seventy-five patients underwent ultrasonographic examination and diagnosed as appendicitis, then the characteristics of ultrasonography were analyzed, classified and correlated with the histologic diagnosis, respectively. Results: All the ultrasonographic findings showed that the appendixes were thickened with the diameter >7mm in adults and with the diameter >6mm in children, and the mucous membrane was coarse with echo interrupted or absent. According to the ultrasonographic features of appendicitis ,five styles were divided: ①simple appendicitis including 2 chronic appendicitis；②purulent appendicitis；③gangrenous appendicitis；④appendiceal abscess；⑤appendicitis with indirect characteristics.Conclusion: Ultrasonography is one of high clinical significant for diagnosis and classification of appendicitis. ......
