valve between the ileum of the small intestine and the cecum of the large intestine; prevents material from flowing back from the large to the small intestine
The ileocecal valve, or ileocaecal valve, is a papillose structure with physiological sphincter muscle situated at the junction of the small intestine and the large intestine, with recent evidence indicating an anatomical sphincter may also be present in humans. Its critical function is to limit the reflux of colonic contents into the ileum. Previous version of this page stated: 'The ileocecal valve is distinctive because it is the only site in the GI tract which is used for Vitamin B12 and bile acid absorption.' what.

Excerpt from abstract: 'The ileocaecal valve, however, does play a substantial role, in that, on the one hand, it performs sphincter and barrier functions against ileocolic reflux of bacteria, while, on the other, its removal involves excision of the right colon and of the terminal ileum.' 2: http://www.ncbi.nlm.nih.gov/pubmed/1949406 Urol Clin North Am. 1991 Nov;18:743-54.

Excerpt from Abstract: 'The loss of the ileocecal valve and ileum segment accelerates intestinal transit time, which does not allow for complete digestion and absorption of food. Water and electrolytes remain associated with undigested food particles and may overwhelm the absorptive capacity of the colon, resulting in an osmotic diarrhea. A second problem is vitamin B12 deficiency. Surgical reduction of sites in the terminal ileum for active and exclusive uptake of vitamin B12 might lead to hypovitaminosis. If this is unrecognized, patients may develop irreversible neurologic injury.'
