An ileostomy is a surgical opening constructed by bringing the end or loop of small intestine (the ileum) out onto the surface of the skin. Intestinal waste passes out of the ileostomy and is collected in an external pouching system stuck to the skin. Ileostomies are usually sited above the groin on the right hand side of the abdomen.

Ileostomies are slowly being replaced by the now preferred alternative J-Pouch or BCIR. This surgery turns the small intestine into an internal reservoir thus eliminating the need for an external appliance.
