The aim of this study was to determine if upper gut function and pancreatic exocrine secretion are affected by the presence of unabsorbed carbohydrate in the distal ileum. In this investigation, starch or glucose was perfused into the canine ileum. This study showed that ileal perfusion of both starch and glucose delayed gastric emptying and prolonged small bowel transit time. Furthermore, glucose had greater effects on gastrointestinal transit time than starch. In contrast, amylase output was increased by ileal perfusion of starch, but was not affected by that of glucose. Our results suggest that the ileal regulation of gastrointestinal transit and amylase output could be mediated by different mechanisms.

UI	MeSH Term	Description	Entries
D007082	Ileum	The distal and narrowest portion of the SMALL INTESTINE, between the JEJUNUM and the ILEOCECAL VALVE of the LARGE INTESTINE.
D008297	Male		Males
D010179	Pancreas	A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
