title: [Multi-institution, multidisciplinary radiology and endoscopy trial of the diagnostic accuracy of the double contrast examination of the stomach surface].
abstract: In 12 X-ray and gastroenterology departments 1570 patients, clinically suspected to have a gastric pathology, have been examined by double contrast (surface) examination of the stomach followed by gastroscopy. Diagnostic accuracy was 93% in respect of endoscopic data, assumed correct by hypothesis. On the basis of a cost and benefit evaluation, made according to the well known criteria, a wider routine use of the double contrast technique is proposed.
