Surgical Procedures: Large Bowel/Colon Resection

What is Large Bowel/Colon Resection?

Large bowel resection, also known as colon resection, is the surgical removal of the diseased portion of the large bowel (otherwise known as the large intestine or colon). An incision is made in the abdomen, and then the diseased part of the large intestine (colon) is removed. The two healthy ends are then sewn back together and the incision is closed.

If it is necessary to spare the colon from its normal digestive work while it heals, a temporary opening of colon onto the skin of the abdominal wall (colostomy) may be done. The proximal end of the colon is passed through the abdominal wall and the edges sewn to the skin. A removable bag is then attached to the skin around the colostomy and the stool then passes into the bag. In most cases, depending on the disease process being treated, colostomies are temporary and can be closed with another operation at a later date.

If a large portion of the bowel is removed or the distal end of the colon is too diseased to reconnect to the proximal intestine, the colostomy may be permanent.

What are the Risks?

As with any surgery, risks include infection and bleeding. Anesthesia-related risks include reactions to medications and problems with breathing.
