A prospective, randomised study of endoscopy and radiology in acute upper-gastrointestinal-tract bleeding.

318 patients admitted to hospital with acute upper-gastrointestinal-tract bleeding were entered into a prospective randomised comparison of investigation by either endoscopy or radiology. Although the diagnostic yield was higher in the endoscopy group than the radiology group, there was no difference between the two groups in management or survival, and the accuracy of the findings as judged independently at operation and/or necropsy was also similar in the two groups. These findings case doubt on the need to provide emergency endoscopic facilities for the investigation of patients with acute upper-gastrointestinal-tract bleeding where radiological services are already adequate.
