title: [The diagnostic value of pharmacologic double contrast and conventional barium meal of the stomach (author's transl)].
abstract: The authors compared the diagnostic accuracy of pharmacologic double contrast, conventional barium meal and oesophago-gastro-duodenoscopy of the stomach in 922 selected patients. The agreement rate between conventional investigation and endoscopy was 70.3%, while it was 83.7% between double contrast studies and endoscopy. Double contrast false positives percentage (48.7%) is bigger than that for conventional technique (38.3%), whilst the latter has a much bigger number of false negatives, both absolutely (169 cases) and relatively (61.7%). Furthermore the association of double contrast and endoscopy was compared with the anatomo-pathological diagnosis in 335 cases. The agreement rate was 94.6%.
