多层螺旋CT与超声检查在急性阑尾炎术前中的应用价值

The Application Value of Multi-slice Spiral CT and Ultrasonography in Acute Appendicitis before Operation

目的比较多层螺旋CT与超声检查在急性阑尾炎患者术前的应用价值。方法以我院2013年4月-2015年4月收治72例住院急性阑尾炎患者作为研究对象,均行超声检查与多层螺旋CT检查,比较两组诊断准确率及不同类型阑尾炎诊断结果。结果 72例急性阑尾炎患者中,超声正确诊断48例,漏诊24例,准确率为66.7%(48/72);多层螺旋CT正确诊断66例,漏诊6例,准确率为91.7%(66/72),差异的比较有统计学意义(χ2=13.642,P=0.000<0.05)。不同阑尾炎类型中,坏疽性阑尾炎两种检查方法的确诊率均为100%,比较无统计学意义(P>0.05);水肿性、化脓性确诊率均为CT高于超声,比较均有统计学意义(P<0.05)。结论与超声检查相比,多层螺旋CT在急性阑尾炎术前中具有更大应用价值,不断诊断准确率更高,同时可有效反映阑尾位置、长短、粗细、走向、粘连与周围渗出情况,利于手术施行,临床应用价值高。

Objective To compare the application value of multi-slice spiral CT and ultrasonography in patients with acute appendicitis before operation. Methods 72 inpatient with acute appendicitis who were admitted into the hospital during April 2013 to April 2015 were treated as the research objects. All of the patients underwent ultrasonography and multi-slice spiral CT examination. The accurate rates and the results of the diagnosis of different types of appendicitis were compared between the two groups. ResultsAmong the 72 patient with acute appendicitis, there were 48 cases correctly diagnosed by ultrasonography and 24 cases missed diagnosed. The accuracy was 66.7%（48/72）. There were 66 cases correctly diagnosed by multi-slice spiral CT and 6 cases missed diagnosed. The accuracy was 91.7%（66/72）. The comparisons were statistically significant（χ2=13.642, P=0.0000.05）. In different types of appendicitis, the accurate diagnosis rate of both the two examination methods for gangrenous appendicitis was 100%. The comparison was not statistically significant（P〈0.05）. The accurate diagnosis rates of CT for edema and suppurative appendicitis were higher than those of ultrasonography. The comparison was statistically significant（P〈0.05）. Conclusion Compared with ultrasonography, multi slice spiral CT is of greater application value in acute appendicitis before operation. The diagnostic accuracy of multi slice spiral CT is higher and it can effectively reflect the position, length, thickness, direction, adhesion and peripheral exudation of the appendix, which is good for the implementation of operation. The clinical application value is high.
