Definition
a small piece of ileum is removed with blood and nerve supply intact. The remainder of the ileum is reconnected to prevent disruption of flow through the bowel. The free segment of ileum is sutured closed at one end, and the other end is brought out to the abdominal wall to create a stoma.
Term
Because the mucous membrane lining the ileum protects the kidneys from asending infection.
