    Abstract:
    In a prospective, blind study of 385 patients with dyspepsia, the diagnostic value of biphasic radiological examination of stomach and duodenum was compared with endoscopy. The patients were examined for presence of peptic ulcers and gastric carcinomas. No golden standard being available, kappa values were calculated for the comparison. The kappa values were 0.67 and 0.77 for gastric and duodenal ulcers, respectively; for gastric carcinomas the value was 0.91. These values indicate good agreement. The sensitivity and specificity of both methods were high; a lower sensitivity of radiological examination for duodenal ulcers was accounted for by ulcers smaller than 5 mm; for larger ulcers, the sensitivity and specificity of both methods were practically the same. It is concluded that the two methods are of equal value for the diagnosis of peptic ulcers and gastric carcinomas. Endoscopy offers the major advantage that biopsy samples can be taken for histological examination or culturing. The biphasic radiological examination, on the other hand, is cheaper and often better tolerated by the patient.
