"Colonic subtotal resection, also known as subtotal colectomy, is a surgical procedure used to treat colonic diseases such asconstipation, colon cancer, ulcerative colitis, and others.~The purpose of this surgery is to remove a portion of the colon in the patient's body. Unlike a total colectomy, which involves removing the entire colon, a subtotal colectomy only removes a portion of the colon. The procedure typically involves removing the diseased part of the colon and reconnecting the remaining colon. This allows for the preservation of some normal colonic function, enabling the patient to have regular bowel movements."
