[Comparison between the diagnostic findings of esophago-gastro-bulboscopy and standard radiographic diagnosis].

On the basis of a computer-supported evaluation of the data of 1,808 patients who underwent endoscopy (endoscopy of the superior alimentary tract) the comparison of X-ray-findings and findings of the endoscopy could be made in 887 patients. For 124 patients with an oesophageal and gastric tumour, respectively, and for 146 patients with a gastroduodenal ulcer a control of the findings by superordinate parameters (findings of operations and post-mortem examinations) are present. The result was an accordance between 90 and 98%. The accordance of the evidence of the two methods varies depending on the group of diagnosis. For the oesophageal carcinoma it is 90%, for the gastric carcinoma ca. 77%, for the ventricular ulcer and the duodenal ulcer in every case 70%, while the X-ray diagnosis "no abnormality discovered" could be endoscopically confirmed only in 56%. From this result necessary conclusions concerning the further concept of the diagnosis of diseases of the superior alimentary tract.
