title: [Diagnostic accuracy of double contrast examination in the detection of gastric polyps (author's transl)].
abstract: Gastric polyps have been found in 2.9% of 4322 consecutive routine double contrast examination of upper gastro-intestinal tract. In 559 patients, endoscopically verified, sensitivity of radiological test was 96% and specificity 96.3%. An agreement index (K-index) was evaluated in a sample of 84 cases. The index value was 0.9 among 2 different radiologists with a similar, high experience and 0.8 among 2 radiologists with different degree of experience in double contrast examination. Our results demonstrate the validity of the double contrast study of the stomach as preliminary to endoscopy.
