Read before the Medical Staff of the Columbus Hospital, Nov. 12, 1925.
In a previous communication,1 it was pointed out that a mass of barium injected into the duodenum was partially divided and passed in opposite directions along that viscus. Similar movements were shown to occur in conditions that permitted the accumulation of barium at any point along the course of the duodenum following the taking of a barium meal. From these observations it was concluded that distention of the duodenum was sufficient stimulus to excite contractions of the musculature about the mass and the subsequent passage of contraction waves in opposite directions along the longitudinal axis of the duodenum. Roentgenographic examinations of the gastro-intestinal tract on a series of 398 consecutive patients over a period of three years corroborate the findings and conclusions previously derived.
Early in the study of duodenal motility, it became apparent that definite symptoms were either directly associated with or immediately followed reverse movements of barium.
