Abstract
Cholecystitis secondary to gallstone migration is the most common suspected diagnosis for right upper quadrant pain in emergency departments, with radiology-performed ultrasound (RADUS) being the main diagnostic tool. The primary aim of this review was to assess the ability of emergency physicians to perform emergency ultrasound (EUS) compared to RADUS to diagnose cholelithiasis and cholecystitis. A systematic search was performed using Embase, Central (Cochrane library), Web of Science, MEDLINE, Google Scholar, prospective trial registries, and OpenSIGLE databases as well as hand-search of articles. Two physicians independently selected the articles. Assessment of methodological quality was performed using the Quality Assessment of Diagnostic Accuracy Studies 2 tool. Clinical and methodological heterogeneity were qualitatively reported and discussed. Seven prospective studies were selected involving a total of 1061 subjects undergoing EUS. The included studies all used RADUS as the reference standard and emergency physician-performed EUS as the index test. Included studies mostly reported diagnostic accuracy for cholelithiasis diagnosis whereas only one study mentioned diagnostic accuracy for cholecystitis. Clinical and methodological heterogeneity between included studies prevented a meta-analysis. This review shows there is good agreement between EUS and RADUS to assess the gallbladder for cholelithiasis and therefore supports its use by emergency physicians for that matter. Nevertheless, this work identified clinical and methodological heterogeneity along with a poor description EUS operators' experience. In the future, larger studies should include a larger population of EUS operators, specify their background, and compare EUS to the final diagnosis to evaluate performances for gallbladder diagnostic accuracy.
