国内超声与CT诊断急性胰腺炎患者符合率Meta分析

目的 系统评价国内超声与CT诊断急性胰腺炎(AP)患者的符合率.方法 检索中国期刊全文数据库(2000～2012年)、万方医学数据库(2000～2012年)及中文科技期刊全文数据库(2000～2012年),纳入超声与CT诊断AP患者的研究文献,手工检索其他相关文献.并对纳入的研究文献进行质量评价,采用RevMan5.1软件进行Meta分析.结果 共有16篇研究文献符合纳入标准.Meta分析结果显示:超声与CT诊断胆源型AP患者符合率差异有统计学意义(P ＜0.01)(RR =1.14、95％CI=1.08～1.19);诊断轻型AP患者符合率差异有统计学意义(P＜0.05)(RR =0.69、95％CI=0.48～1.00)；诊断重型AP患者符合率差异有统计学意义(P＜0.01)(RR=0.70、95％CI=0.55～0.91).结论 对于胆源型AP超声优于CT;对于轻型和重型AP诊断CT优于超声.二者相互结合使用,有利于AP的诊断.

Coincidence rate meta analysis on diagnostic value of ultrasound or CT image in patients with acute pancreatitis

Objective To study diagnostic value of ultrasound and CT image comparatively in patients with acute pancreatitls from coincidence rate meta analysis. Methods We picked out the research papers about diagnostic value of ultrasonography and CT in acute pancreatitis by means of searching Chinese Journal Full-text Database（2000- 2012 ）, Wanfang medical database（2000--2012） and Chinese science and technology periodical full-text database（2000- 2012） combined with searching other related literature. And then the data from these research papers were analyzed by RevManS. 1 software for meta analysis. Results A total Of 16 studies met criteria. Meta analysis showed that there was significant difference in diagnostic accuracy between ultrasound and CT image in patients with biliary acute pancreatitis （ P 〈0.01）（ RR = 1.14,95 % CI = 1.08--1.19）. Furthermore, there was significant difference in diagnostic accuracy between ultrasonography and CT in patients with severe acute pancreatitis （ P 〈0.01）（ RR = 0.70,95 %CI = 0. 55-- 0.91）, there was difference in diagnostic accuracy in mild acute pancreatitis between the two kinds of image technologies（ P 〈 0.05 ） （ RR = 0.69,95% CI = 0.48 -- 1.00）. Conclusion Ultrasonography is superior to CT for acute gallstone pancreatitis. CT is superior to ultrasonography for mild acute pancreatitis and severe acute pancreatitis, while CT combined with ultrasonography is most helpful for the diagnosis of severe acute pancreatitis.
