A roentgen study of the effect of total pancreatectomy on the stomach and small intestine of the dog.

Abstract

Numerous and extensive studies (1, 2, 3, 5, 7, 10, 12–15) of extrinsic and intrinsic influences upon the radiologic appearance of the small intestine have revealed that, though the small bowel is sensitive to a multitude of stimuli, it reacts in a limited manner. The finding of an altered motor pattern can therefore rarely be attributed to a definite entity. Limitations of the small-intestinal roentgen examination will continue until the stimuli and the motor changes they produce are more fully understood. Among the factors requiring further study are the internal and external secretions of the pancreas. Loss of external secretions results in partially digested food products, principally proteins and fats. At least some of these products are felt to have a profound influence upon intestinal motor function (8, 15, 16). While these indirect effects of pancreatic enzymes upon the intestinal tract seem established, the direct effects, as measured by an inert water-barium meal, remain to be determined. It is t...
