Abstract:

Objective To systematically evaluate the diagnostic accuracy of contrast-enhanced ultrasound (CEUS) in diagnosing hepatic echinococcosis. Methods By searching keywords combined with free words, articles reporting CEUS in diagnosing hepatic echinococcosis published before June 2023 were searched in the databases, including Pubmed, EMBASE, Cochrane Library, CBM, CNKI, Wanfang and CQVIP. According to the inclusion and exclusion criteria, eligible articles were screened. Data of general information, true positive, false positive, false negative, and true negative were extracted from the included articles. Using the QUADAS-2 tools to assess the included studies. Meta-disc1.4 and RevMan5.4 software were used for meta-analysis. The pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were calculated. The diagnostic odds ratio(OR) and area under the SROC curve (AUC) were calculated. Stata14.0 software was used to draw the Galbraith plot to perform heterogeneity analysis on the research data. Results According the inclusion and exclusion criteria, 7 articles were included with 348 patients. The pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic OR and AUC of CEUS in diagnosing hepatic echinococcosis was 0.96 (95%CI 0.92-0.98), 0.88(95%CI 0.79-0.93), 5.73 (95%CI 1.24-26.58), 0.07 (95%CI 0.03-0.18), 95.32(95%CI 22.02-412.60), and 0.9767, respectively. According to the pooled sensitivity, specificity and AUC, CEUS had a high diagnostic efficacy in diagnosing hepatic echinococcosis. The Galbraith plot showed that all articles were distributed on both sides of the solid red effect line and within the green confidence interval range, indicating no overall heterogeneity in this study. Conclusion CEUS has a high efficacy in the diagnosis of hepatic echinococcosis and can serve as a new method for clinical diagnosis of hepatic echinococcosis.
