MOTOR PHENOMENA OCCURRING IN NORMAL STOMACHS, IN THE PRESENCE OF PEPTIC ULCER AND ITS PAIN, AS OBSERVED FLUOROSCOPICALLY

Abstract
This communication embodies the principal results of fluoroscopic observations of the stomachs of normal men and of patients with ulcer of the stomach or duodenum, after the feeding a meal composed of meat and barium, which we have recently made. The ulcer patients were studied in order to obtain detailed information regarding gastric motor phenomena occurring throughout the period in which the stomach was emptying itself and during the occurrence of pain due to the presence of the ulcer; and, also, to attempt to establish an objective method for determining the effects of therapeutic measures. The normal patients were studied to obtain further data as to normal motor activity. It may seem that there is no need for further roentgen-ray observations on the motor activities of the normal human stomach, for considerable data1 are available describing such observations after the ingestion of various kinds of solid foods. But clinicians and
