Is pillcam ESO ( ® ) more accurate than clinical scoring systems in risk stratifying emergency room patients with acute upper gastrointestinal bleeding?
In emergency room patients with acute UGIB, neither the Rockall nor the Blatchford scores were able to differentiate high- and low-risk patients identified at endoscopy. Live view VCE, however, was accurate in predicting high-risk endoscopic stigmata, and may be better suited as a risk stratification tool. Additional studies with a larger cohort will be required to validate these findings.
