Subtotal Proctocolectomy is a major colorectal procedure used to remove most or all of the colon while preserving part of the rectum. It may be performed for conditions such as severe ulcerative colitis, Crohn's disease, familial adenomatous polyposis, colorectal cancer, or other extensive diseases affecting the colon. Depending on the patient's condition, the procedure may be followed by an ileostomy or reconstruction with a future restorative procedure.
