Diagnostic performance of ultrasound in the assessment of gastric contents: a meta-analysis and systematic review

ConclusionUltrasound techniques have high diagnostic accuracy in assessing the nature of gastric contents and their volume in patients. However, most of the studies were feasibility studies with small sample sizes, lacked standardization, and had high risk of bias. More studies are needed in the future to investigate the diagnostic performance of gastric ultrasound assessment techniques.Critical relevance statementUltrasonography can be used to assess gastric contents, but standardized data integration and reporting are needed to account for the diagnostic capabilities of this technology.Key points• Ultrasound is a safe and feasible tool for assessing gastric contents.• Ultrasound has good diagnostic performance for gastric contents.• There is still a certain heterogeneity within our analysis process; more research is needed in the future to improve our results.Graphical Abstract
