Prevalence of upper gastrointestinal disease in relation to age: radiologic and clinical implications.

Reports of 1126 endoscopies were reviewed to determine the age-related prevalence of upper gastrointestinal (UGI) diseases as a guide to radiologists performing UGI examinations. Results indicate that (1) there were positive findings in 78% of all endoscopic examinations, and thus most symptomatic patients can be expected to have at least one UGI abnormality; (2) many patients with UGI symptoms have two or more reportable disease processes; (3) the prevalence of serious or life-threatening disease, such as cancer or large ulcers, rises steadily with age; and (4) after age 60, approximately 60% of symptomatic patients have a serious UGI disease. Based on these findings, radiologists should not hesitate to make the diagnosis of multiple abnormalities and should expect to diagnose at least one abnormality in most symptomatic patients having an UGI study. Also, because of the high prevalence of serious lesions in the elderly, endoscopy should be considered for the initial examination of an elderly patient if poor physical status would render the radiologic examination difficult or unreliable.
