A bowel resection is a surgical procedure in which a part of the large or small intestine is removed. It may be performed due to cancer, necrosis, enteritis, diverticular disease, or a block in the intestine due to scar tissue. Other reasons to perform bowel resection include ulcerative colitis, traumatic injuries, precancerous polyps, and familial polyposis.

Some patients require ileostomy after this procedure.
