Abstract:Objective To evaluate the diagnostic value of contrast-enhanced harmonic endoscopic ultrasound (CEH-EUS) in pancreatic carcinoma.Methods Studies on CEH-EUS for the assessment of pancreatic carcinoma were searched in PubMed, EMBASE, and the Cochrane Library. The documents were screened according to the inclusion and exclusion criteria. Then evaluate the quality of the included studies. The sensitivity (SE) and specificity (SP) were calculated by Stata software. Forest plots and a summary receiver operating characteristic (SROC) curve were drawn, and the area under the curve (AUC) were calculated. Explore the degree and source of heterogeneity.Results A total of 15 studies and 1 693 patients were included, the combined SE was 0.91 (95%CI: 0.87~0.94), SP was 0.79 (95%CI: 0.71~0.85), SROC AUC was 0.93 (95%CI: 0.90~0.95).Conclusion CEH-EUS is effective in the diagnosis of pancreatic cancer.
