[Trickling mucography under high pressure and with moderate contrast. First phase of gastroduodenal examinations (author's transl)].

The authors describe a simple and reliable technique of successive mucography of the anterior and posterior surfaces of the stomach. The examination is begun in a seated position, in dorsal horizontal and trickling provides perfect conditions of study, selective and with no opaque superimposition, of the posterior surface of the stomach, the site of 90% of organic lesions. Study of the anterior surface is also simplified. Practically no patient cooperation is required and the technique may be used in the elderly and those with physical incapacity. The aim is to obtain a morphologically and physiologically pure picture of the mucosa and the gastric folds. Very small lesions may be visualised without resort to other techniques and the study of cases of gastritis is greatly simplified.
