摘要
目的 探讨急性阑尾炎的多层螺旋CT表现与病理的相关性,为外科手术及治疗提供更准确的信息.资料与方法 以循证医学为基础,回顾性分析160例急性阑尾炎患者的CT征象,并与手术病理结果进行对照.结果 急性阑尾炎的CT征象中,阑尾增粗直径＞6 mm （96.25％）、阑尾积液（60.63％）、阑尾及周围肠壁增厚水肿（80.63％）、阑尾周围炎及邻近筋膜增厚（73.75％）、阑尾腔内粪石（46.25％）有一定的特异性.阑尾的解剖位置变异较大,以回肠前位（30.63％）、盆位（26.25％）、盲肠后位（21.25％）多见.160例患者阑尾均发生病理改变,24例穿孔CT分级为3～5级.结论 急性阑尾炎的CT分级可以预测外科术后病理结果,为临床选择治疗方法提供参考.
Purpose To explore the correlations of multi-slice spiral CT features and pathological findings of acute appendicitis, so as to provide more accurate evidence forsurgical treatment. Materials and Methods Based on evidence-based medicine, the CTfeatures of 160 patients with acute appendicitis were retrospectively analyzed, and thencompared with pathological findings. Results The CT scans demonstrated such specificityof acute appendicitis as appendix thickness （diameter 〉6 mm） （96.25%）, appendix effusion （60.63%）, intestinal wall thickness and oedema around appendix （80.63%）,periappendicitis and adjacent fascia thickness （73.75%） and alvine calculus in appendix（46.25%）. The anatomical position of appendix varied greatly and most appeared beforeileum （30.63%）, in pelvic cavity （26.25%） and after cecum （21.25%）. All 160 casesshowed pathological changes and 24 cases were accomplished with perforation （grade 3-5according to CT scan）. Conclusion CT grade can predict the pathological results of acuteappendicitis and provide reference for clinical treatment.
