. The stomach and sophagus : a radiographic study . and the patient nearly alwayscomplains that he feels his food lying on hisstomach for hours. Tonic action is called intoplay continuously, for the stomach is never empty,and by degrees the organ becomes atonic. Owingto the failure of tone, the stomach becomes stretched,the muscle is thinned out and cannot produce peris-taltic waves of the same power as formerly. Notonly so, but the work it is called upon to do in liftingthe food to the pylorus increases as the greatercurvature sags down towards the pelvis. Evenwhen the stomach becomes quite atonic, its lowestborder sometimes as low as the symphysis pubis, Ihave very seldom, if ever, failed to see evidence ofperistalsis, provided the apparatus was workingefficiently. In one of these atonic cases I found quitea quantity of bismuth food in the stomach five daysafter it had been given, in spite of persistent vomit-ing. (Figs. 18 and 20)Type 2. I have no evidence whether or not the earlystages in these cases are the same as in type 1, but. Fig. 20. Radiogram of a typical case of chronic pyloric obstruction,Type 1. The plate was taken 21 hours after the food was given, andthe bismuth is seen lying about 5 inches below the level of theumbilicus. None of the food appears to have reached the caecum. .\little more food has been given and can be seen sliding down betweenthe collapsed walls of the upper part of the stomach. The radiogramdoes not happen to show any of the blobs of bismuth food fallingfrom this point into the lower part of the stomach. X is the position of the umbilicus.
