What is a Loop Stoma or Loop Ostomy?
A loop stoma is a stoma where both the upstream (proximal) and downstream (distal) openings of the bowel are brought out through the same place in the abdominal wall (see photo A). The proximal opening of the stoma drains stool from the intestine, while the distal opening of the stoma (the mucous fistula) drains mucus from the part of the bowel that leads to the anus (or internal pouch).
