超声显像对急性阑尾炎的诊断及误漏诊分析

Ultrasonographic Diagnosis and Misdiagnosis of Acute Appendicitis

目的探讨超声诊断急性阑尾炎的价值及其误漏诊原因。方法对398例急性阑尾炎患者,用高频和低频探头相结合的扫查方法,在患者右下腹行纵切、横切、斜切、旋转、延伸、多切面扫查,显示阑尾。并观察阑尾大小、形态及其周围组织回声与腹腔情况,并对各型阑尾炎检查结果与手术病理对照。结果超声诊断急性阑尾炎符合率为89.7%(357/398),其声像图有特征性表现,而且易于诊断和鉴别诊断。结论高低频探头联合应用对急性阑尾炎诊断有很高的准确性,具有很高的临床实用价值,为急性阑尾炎的诊断,提供了一个直接、简便、安全、首选的影像学检查方法。

Objective To investigate the value of the ultrasonic diagnosis on acute appendicitis and the reason of misdiagnosis. Methods The low and high frequency probe pressing manner is used to take longitudinal, horizontal, rotary, outstretched, multidimensional, diagonal scanning in 398 patients with acute appendicitis. To display appendix, its size and shape, and the tissue around it and other organs was observed. All cases were contrasted with operation and pathology. Results The coincidence rate of the ultrasonic diagnosis on acute appendicitis was 89.7%. The ultrasonic imaging was of characteristic and easy to diagnose and antidiastole. Conclusion The high-low frequency ultrasonic examination was of high accuracy in the diagnosis of acute appendicitis. It had a high practical value in the clinic. It could be the direct simple,safety,preferred manner in iconography for diagnosis of acute appendicitis.
