High rate of over-staging of Barrett's neoplasia with endoscopic ultrasound: Systemic review and meta-analysis
2018
Abstract Background The use of endoscopic ultrasound (EUS) to stage patients with Barrett's esophagus (BE) with suspected neoplasia is controversial due to high rates of over-staging. However, this rate of over-staging has not been adequately investigated or quantified. Aim To determine the rate of over-staging related EUS in this population. Methods Search included Medline, Embase, Web of Science, and Cochrane Central ending on 9/30/2016. The primary effect-estimate of interest was the false positive rate of advanced disease on EUS at the tumor level (T1a vs. T1b). Secondary outcomes included false detection rate, false negative rate, accuracy, sensitivity, and specificity. Study heterogeneity was assessed using the I2 and Cochrane's Q . Results Of 1872 studies, 11 met our inclusion criteria totaling 895 patients. Based on random effects models, the pooled FPR for advanced disease was 9.1% ([6.5–12.5%], p p p = 0.004. Conclusions The use of EUS in BE patients with dysplasia and early neoplasia results in a large proportion of patients falsely over-staged and under-staged.
