Abstract
Objective: It is unclear whether point-of-care ultrasound (POCUS) by emergency medicine physicians is as accurate as radiology-performed ultrasound (RADUS). We aim to summarize the diagnostic accuracy of ultrasonography for intussusception and to compare the performance between POCUS and RADUS. Methods: Databases were searched from inception through February 2018 using pre-defined index terms. Peer-reviewed primary studies that investigated the diagnostic accuracy of ultrasound for intussusception in children were included. The study is reported using Preferred Reporting Items for a Systematic Review and Meta-analysis of Diagnostic Test Accuracy Studies (PRISMA-DTA). Meta-analysis of the diagnostic accuracy of ultrasound for intussusception was conducted using the random-effects bivariate model. Subgroup analysis (POCUS vs RADUS) was also performed. Meta-regression was utilized to determine if the diagnostic accuracy between POCUS and RADUS was significantly different. Results: Thirty studies (n = 5249) were included in the meta-analysis. Ultrasonography for intussusception has a sensitivity: 0.98 (95% CI: 0.96–0.98), specificity: 0.98 (95% CI: 0.95–0.99), positive likelihood ratio: 43.8 (95% CI: 18.0–106.7) and negative likelihood ratio: 0.03 (95% CI: 0.02–0.04), with an area under ROC (AUROC) curve of 0.99 (95% CI: 0.98–1.00). Meta-regression suggested no significant difference in the diagnostic accuracy for intussusception between POCUS and RADUS (AUROC: 0.95 vs 1.00, p = 0.128). Conclusions: Current evidence suggested POCUS has a high diagnostic accuracy for intussusception not significantly different from that of RADUS.
