We used upper digestive endoscopy UDE.to determine the prevalence of H. pylori and NSAIDs/ASA in patients with association with peptic ulcers, as well as determining the percentage of ulcers which are not associated with either diagnosis. The study included immunocompetent adult patients over 18 years of age who were diagnosed with DU between January 2007 and November 2008 at the gastroenterology units of El Tunal Hospital and Fundadores Clinic.
