Comparison Between Vulues Of CECT And CEUS In Diagnosis Of Focal Gallbladder Leisions:A Meta Analysis

Objective:To contrast the diagnostic value of contrast-enhanced CT(CECT)and contrast-enhanced ultrasound(CEUS)for focal gallbladder lesions(FGL)by meta-analysis.Methods:Databases including PubMed,Wiley InterScience?EBSCO?EMBASE,OVID,The Cochrane Library,CNKI,CBM,WanFang Data and VIP were searched for diagnostic tests about CECT and CEUS for focal gallbladder lesions from inception to August,2016.The meta-analysis was performed by Stata12.0 and Meta-Disc 1.4 software.Results:25 studies were totally included,including a total of 2469 patients.The results of meta-analysis showed that:the pooled Sen,Spe,+LR,-LR,and DOR(combined effect and its 95%CI)in the CECT group were 0.91[95%CI(0.87,0.94)],0.71[95%CI(0.67,0.75)],4.77[95%CI(2.57,8.84)],0.12[95%CI(0.09,0.18)],44.89[95%CI(17.17,117.35)]and in the CEUS group were 0.91[95%CI(0.88,0.94)],0.95[95%CI(0.94,0.96)],12.44[95%CI(8.49,18.25)],0.10[95%CI(0.07,0.14)],139.52[95%CI(73.13,266.20)].There was no significant difference between the CECT group(0.9627)and the CECT group(0.9687)in the area under the summary receiver operating characteristic(SROC)curve(Z=0.5435,P>0.05).Conclusion:CECT and CEUS have similar diagnostic efficacy for focal gallbladder lesions.The two measures have their own preponderance and both of them can be used as important inspection method.The conclusion is still needed to carry out more high quality research and demonstrations.
