Function&Application
Sincalide may be used to stimulate gallbladder contraction, as may be assessed by contrast agent cholecystography or ultrasonography, or to obtain by duodenal aspiration a sample of concentrated bile for analysis of cholesterol, bile salts, phospholipids, and crystals. It can also be used to stimulate pancreatic secretion (especially in conjunction with secretin) prior to obtaining a duodenal aspirate for analysis of enzyme activity, composition, and cytology. In some instances it is used to accelerate the transit of a barium meal through the small bowel, thereby decreasing the time and-extent of radiation associated with fluoroscopy and x-ray examination of the intestinal tract.
