We have thus far made roentgen ray studies of sixty-six cases of chronic gastric intestinal disorders in children from 3 months to 15 years of age. The vast majority were between 3 and 6 years of age. Many roentgenograms were taken, in some instances as many as twenty, in order to determine the emptying time of the stomach or intestine, or both.
Case 1.—Megacolon; dilated sigmoid.—A boy aged 8 years, had an enormous sigmoid pouch with a capacity of at least two pints (Fig. 1). There was displacement of the liver due to the pressure exerted by the massive dilatation of the colon. The bismuth meal did not disappear entirely from the intestinal canal in seventeen days. One can readily appreciate what a difficult matter it would be to carry out any satisfactory treatment in a case of this kind without roentgen-ray examination. There was extreme abdominal distention
