To the Editor: Dr. Peterson and his colleagues1 report that routine early endoscopy does not influence the outcome in acute upper-gastrointestinal-tract bleeding (April 16, 1981, issue). Their study has particular value in that the population examined contained a high proportion of patients with alcoholic liver disease, whereas there were few such patients in the investigation that we conducted here. We were surprised to read that Dr. Peterson and his colleagues found two drawbacks of our study: that patients were not entered in a consecutive fashion and that “many patients” underwent endoscopy more than 24 hours after admission.
