Gastroparesis: PREVALENCE AND ETIOLOGY Part 3

GastroparesisMost cases of chronic gastroparesis are presumed to result from abnormalities in the gastric smooth muscle and/or its intrinsic (myenteric) or extrinsic (parasympathetic and sympathetic) nervous innervation, although histological changes are not always apparent. It has been suggested that a delay in gastric emptying may reflect an increase in small intestinal feedback. While this hypothesis has not been formally tested, it is recognized that, in patients with exocrine pancreatic insufficiency, gastric emptying of extracellular fat is accelerated due to impaired small intestinal feedback mechanisms (ie, fats have to be digested to fatty acids to slow gastric emptying), and this is likely to contribute to malabsorption. There is evidence that so-called ‘early’ type 2 diabetes mel-litus may also be associated with accelerated gastric emptying. Rapid gastric emptying is otherwise usually iatrogenic. In patients with previous duodenal ulceration and those with the Zollinger-Ellison syndrome, the rate of gastric emptying may be faster, but there is substantial overlap with the normal range.
