[Comparative radiographic study of the stomach using technics of double contrast].

One hundred patients with gastroduodenal symptoms were studied: 50 at a general hospital and 50 at a private hospital. The first group was studied with the Japonese method recommended by Heizaburo Ishikawa and used in Venezuela with some modifications by Zaidman. The second group was studied with the technique developed by Valencia-Parparcén. In addition, in both groups 4.5 mg of an anticholinergic drug (Hsp-2986 Merck-Darmstad-Germany) was applied intravenously to obtain gastroduodenal hypotony. The results from both groups showed that double contrast X-rays are better than the standard and are important factors in the judgment of the radiological diagnosis of gastroduodenal diseases. The methods do not exclude, but rather complement, each other, and are important contributions when a radiography in series with dosified compression through fluoroscopy cannot be carried out under optimum conditions.
