Stagnation at the ileocaecal junction

The ileocaecal junction divides the terminal small intestine from the caecum. The junction or sphincter appears to formed by papillary protrusions into the lumen of the caecum, rather than two flat lips of a valve11. Its function seems to be to retain chyme in the small intestine until digestion is largely complete and then to empty its contents into the large bowel. The ileocaecal junction also serves to prevent the spread of the colonic bacteria into the small intestine12. Contraction of the ileocolonic sphincter is produced by a-adrenergic agonists including phenylephrine, adrenaline and noradrenaline, and by cholinergic agonists such as bethanechol, whereas pure b-adrenergic agonists, such as isoprenaline, cause relaxation13.
