Ileostomy can refer to a stoma (surgical opening) constructed by bringing the end or loop of small intestine (the ileum) out onto the surface of the skin and to the surgical procedure which creates this opening. Intestinal waste passes out of the ileostomy and is collected in an artificial external pouching system which is adhered to the skin. Ileostomies are usually sited above the groin on the right hand side of the abdomen.
