An ileostomy (continent ileostomy, K-pouch) may be necessary when the portion of the small intestine called the ileum is damaged to the point that it cannot eliminate waste. The ileostomy is a connection from the end of the ileum to the skin of the abdomen. It is an opening that is created so waste can drain out of the body and into a bag. In a K ileostomy, the waste is collected inside the body and a catheter can be inserted to drain it.
