高低频探头联合诊断阑尾炎的应用价值

The Application Value of Combined Use of High-frequency and Low-frequency Probe Ultrasonography for the Diagnosis of Appendicitis

目的:探讨超声高低频探头配合应用诊断阑尾炎价值。方法:对132例阑尾炎患者,采用飞利浦公司LD11及德国西门子公司ACUSON X300彩超诊断仪,线阵高频为10.0MHz,低频凸阵探头频率为3.5MHz,使用高低频探头配合应用诊断分析方法。结果:132例患者中,急性单纯性阑尾炎64例,其中低频探头诊断率22%,高低频探头联合诊断率100%;急性化脓性阑尾炎35例,其中用低频超声诊断率42%,高低频探头联合诊断率89%;坏疽性阑尾炎及穿孔性阑尾炎23例,其中低频超声诊断率78%,高低频探头配合诊断率96%;慢性阑尾炎6例,其中低频探头诊断率25%,高低频探头诊断率100%;非阑尾炎4例。结论:高低频探头配合应用超声诊断阑尾炎可以起到优劣互补作用,可提高阑尾炎分型及诊断率。

Objective：To discuss the application value of combined use of high-frequency and low-frequency probe ultrasonography for the diagnosis of appendicitis.Methods：132patients with appendicitis,ultrasonic diagnosis was assessed for all the patients with ACUSON X300 color ultrasound system,which was purchased from SIEMENS.The frequency of high-frequency detector was 10.0MHz,and the frequency of low-frequency probe was 3.5MHz.Results：In132patients,64 cases of acute simple appendicitis,low-frequency probe diagnostic rate of 22%,high frequency probe combined diagnostic rate by 100%;and 35 cases of acute purulent appendicitis with low-frequency ultrasound diagnostic rate 42%,high frequency probe combined diagnostic rate by 89%;gangrenous appendicitis and perforated appendicitis23 cases,including low frequency ultrasound diagnostic rate 78%,high frequency probe combined diagnostic rate by96%;6cases of chronic appendicitis,low-frequency probe diagnostic rate of 25%,high frequency probe combined diagnostic rate by 100%;the 4cases of appendicitis.Conclusion：The application of high frequency probe ultrasonic diagnosis of appendicitis can play agood complementary role,can improve the classification and diagnostic rate of appendicitis.
