浅析阑尾炎的超声诊断

Ultrasound Diagnosis of Appendicitis

目的：研究分析阑尾炎临床超声图像情况，为阑尾炎超声诊断提供参考。方法2011年～2012年我院接收了82例阑尾炎超声图像诊断患者，对这些患者的超声图像和病理结果进行比较、观察、分析。结果单纯性阑尾炎、急性化脓性阑尾炎的声像图存在差异性，阑尾体积小、位置不定，加上肠管有气体感染，所以会有机率出现假阴结果，全部患者接受超声诊断后，有66例表现出阑尾病变，准确率是80.49%，共有16例漏诊病例，有9例是急性单纯性阑尾炎，3例慢性阑尾炎，3例回盲肠后位，1例肝下阑尾。结论各类阑尾炎都有各自的声像特点，急诊化脓性阑尾炎患者的声像图比急性单纯性阑尾炎更加明显，使用高低频探头进行扫查，对回盲肠蠕动情况进行观察分析，确定右下腹是否有不均质高回声团，根据临床表现进行综合判断。

Objective To study appendicitis clinical ultrasound images,and to provide a reference for appendicitis ultrasonography.Methods Received 82 cases of patients diagnosed with appendicitis ultrasound image from 2011 to 2012 in our hospital,ultrasound image and pathological findings in these patients were compared,observed and analyzed. Results There are differencesin simple appendicitis and acute suppurative appendicitis sonographic. Smal size of appendix,location uncertain,with intestinal gas infection had chance of a false negative result. There were 66 cases showed lesions appendix,the accuracy rate was 80.49%,a total of 16 cases of missed cases. There were 9 cases of acute simple appendicitis,3 cases of chronic appendicitis,3 cases of posterior ileocecal,1 case of liver appendix under.Conclusion Al kinds of appendicitis have their own audio and video features,emergency suppurative appendicitis in patients with sonographic more pronounced than acute simple appendicitis,using high-frequency scanning probe. For ileocecal bowel movements are observed and analyzed to determine whether there is a right lower quadrant hyperechoic heterogeneous group,and need comprehensive judgments based on clinical manifestations.
