[The value of double contrast radiological exploration in the study of pathological appearances of the greater curvature of the stomach (author's transl)].

The authors indicate the special points relative to effective double contrast radiological exploration of the greater curvature of the stomach (high titre barium suspension, with high covering power; maximal insufflation of the gastric cavity; decubitus films always complemented by filling images in procubitus and in a vertical position. They then present the principal features which may be encountered using the method: -addition images in relation with ulcerated lesions; -lacunae indicative of localised parietal proliferation; - "double contour" appearances corresponding to infiltrating tumors with a broad surface; - "thick folds" of the greater curvature which, apart from the classical causes, should first suggest an inflammatory or tumoural process in the underlying pancreas; - extrinsic imprints, the topographical location and appearances of which may indicate their origin.
