急性阑尾炎及其伴相关并发症的CT影像表现及诊断价值分析

Imaging Findings and Diagnostic Value of CT in Acute Appendicitis and the Associated Complications

目的研究急性阑尾炎及其伴相关并发症的CT影像表现及诊断价值。方法选取我院2012年3月至2015年9月62例临床怀疑有急性阑尾炎患者为研究对象,采用CT检查,以手术病理诊断结果为金标准,评估CT诊断急性阑尾炎的诊断价值。结果 62例患者手术病理诊断为急性阑尾炎55例,CT诊断为急性阑尾炎54例,急性阑尾炎CT正确检出53例,CT诊断急性阑尾炎的灵敏度、特异度、诊断符合率分别为96.4%、85.7%、95.2%,急性阑尾炎的CT表现为阑尾肿胀增大、管壁增厚、阑尾周围炎性渗出、阑尾粪石、阑尾腔积液、阑尾周围脓肿等。结论 CT检查可以及时诊断急性阑尾炎,有效减少漏诊、误诊情况的发生,对急性阑尾炎的诊断和治疗具有重要作用。

Objective To study the imaging findings and diagnostic value of CT in acute appendicitis and the associated complications. Methods Sixty-two patients with suspected acute appendicitis admitted in onr hospital between March 2012 and September 2015 were selected as study subjects and were examined by CT. With the results of surgical and pathological diagnosis as the golden standard, the diagnostic value of CT in the diagnosis of acute appendicitis was evaluated. Results Among the 62 cases, 55 cases were diagnosed as acute appendicitis. CT diagnosedacute appendicitis in 54 cases, and 53 cases with acute appendicitis were correctly detected by CT. The sensitivity, specificity and accuracy of CT in the diagnosis of acute appendicitis were 96.4%, 85.7% and 95.2%, respectively. The CT findings of acute appendicitis included enlarged appendix, tube wall thickening, inflammatory exudation around the appendix, stercolith in the appendix, appendix cavity effusionand abscessaround the appendix, etc. Conclusion CT examination can diagnose acute appendicitis in time, effectively reduce the incidence of missed diagnosis and misdiagnosis, which plays an important role in the diagnosis and treatment of acute appendicitis.
