  • Title: [A comparison of radiology and endoscopy in the diagnosis of gastric and duodenal ulcers(author's transl)].
    Author: Stender HS, Seigert E, Luska G, Otto P.
    Journal: Rofo; 1975 May; 122(5):381-5. PubMed ID: 125680.
    Abstract:
    The results of endoscopy and radiology were compared in 455 patients, 250 with gastric ulcers and 205 with duodenal ulcers. Accuracy of endo- scopy for gastric ulcers was 95% and for duodenal ulcers 92%. Findings were judged on the results of endoscopy. The radiological findings were related to the endoscopic diagnosis and radiological examinations were carried out on out-patients as well as in-patients. 20% of gastric ulcers in out-patients were missed, and 10% of those in in-patients. Of duodenal ulcers, 27% of out-patients and 8% of in-patients were missed. Gastric ulcers missed radiologically were usually small or superficial and situated predominantly in the upper third of the stomach or in the antrum. Duodenal ulcers tended to escape radiological diagnoSIS if they were linear in shape. Improved technique and greater experience of the examiner increased the radiological accuracy significantly.
