Diverting Loop Ileostomy

A diverting loop ileostomy is a surgical procedure used to bypass a portion of the large intestine (colon). It is typically done when the rectum and anus need to be removed due to conditions such as cancer, inflammatory bowel disease, or radiation injury. This procedure involves separating the colon from the small intestine, creating two separate lumens that lead to two separate stomas (openings) on the abdominal wall. The contents of the small intestine are then diverted through one of the stomas creating a loop ileostomy, while the colon heals in preparation for a later reconnection procedure. Diverting loop ileostomies are beneficial because they provide temporary relief from digestive issues and reduce the risk of serious complications from the underlying condition. In addition, the temporary ileostomy helps to reduce the workload of the colon and the risk of anastomotic failure during the reconnection procedure.
