An ileostomy is a surgically formed opening in the ileum, which is the last part of the small bowel before it connects onto the large bowel (colon). The ileum is brought to the surface of the abdomen as an opening called a stoma. Watery diarrhoea passes through the stoma and is collected in a small plastic bag, called an ileostomy bag. An ileostomy can be temporary or permanent.
