title: The value of gastroscopy in clinical diagnosis: a computer-assisted study.
abstract: The additional information obtained by gastroscopy in patients already examined by upper gastrointestinal roentgenography was assessed. For this purpose, a data sheet for computer analysis was filled in at the time of gastroscopy and again at patient dismissal. Overall, gastroscopy resulted in an altered diagnosis in 18 percent of 1, 368 examinations, and in another 7 percent of cases there were findings of possible clinical significance. Gastroscopic findings differed significantly from x-ray findings in 7 to 35 percent of cases, depending on the indication for the procedure.
