腔内凸阵探头在急性阑尾炎诊断中的临床价值

摘要

Objective:To investigate the clinical value of Cavity convex array probe in the diagnosis of acute appendicitis. Methods:The low-frequency convex array abdominal probe, high-frequency linear array probe, and cavity convex array probe with contrast examination, were used in 54 patients, who were suspected of having acute appendicitis. We firstly determined the appendix and its location, made the diagnosis of appendicitis according to the diameter and length of the appendix, wall echo and echo chamber, mesenteric lymph node enlargement, and other changes around the appendix with or without effusion and. Finally, compared examination results with pathological findings. Results: By use of low-frequency convex array abdominal probe. 28 cases were correctly diagnosed with acute appendicitis. 20 were missed diagnosis, and 4 were excluded acute appendicitis, with the diagnostic coincidence of 58. 3%. By the means of high-frequency linear array probe. 43 cases were correctly diagnosed, and 5 were missed diagnosis, with the diagnostic coincidence of 89. 6%. By cavity convex array probe. 42 cases were correctly diagnosed. 6 cases were missed diagnosis, and 3 cases were excluded acute appendicitis, with diagnostic coincidence of 87. 5%. Conclusion:Cavity convex array probe can locate the position of appendicitis. Cavity convex array probe is profit for understanding the relationship between the appendix with the surrounding organs and lesions. Cavity convex array probe can not only make a more clearly diagnosis of appendicitis, but also is helpful for understanding the severity of appendicitis. It has high clinical value in the diagnosis of acute appendicitis by cavity convex array probe.%目的:探讨腔内凸阵探头在急性阑尾炎诊断中的临床价值.方法:分别用腹部低频凸阵探头、高频线阵探头、腔内凸阵探头对54例临床可疑急性阑尾炎患者进行检查,首先判断阑尾及其位置,再根据阑尾管径及长径、管壁回声及腔内回声、肠系膜淋巴结有无肿大、阑尾周围有无积液等改变诊断阑尾炎,并将检查结果与手术病理结果对比.结果:经腹部低频凸阵探头诊断急性阑尾炎28例,漏诊20例,诊断符合率为58.3％,排除急性阑尾炎4例；高频线阵探头诊断急性阑尾炎43例,漏诊5例,诊断符合率为89.6％；腔内凸阵探头诊断急性阑尾炎42例,漏诊6例,诊断符合率为87.5％,排除急性阑尾炎3例.结论:腔内凸阵探头既可定位诊断阑尾的位置,了解阑尾与周围脏器的关系及病变情况,减少误诊、漏诊率.也可定性诊断阑尾的严重程度,对诊断急性阑尾炎有较高的临床价值.
