After stoma rejection, the patient can be discharged from the hospital in about one week after surgery, because the incision has basically healed, the patient can eat and defecate normally, and the bowel function has returned to normal. Stoma is mostly used in malignant tumor surgery to prevent anastomotic fistula and to provide postoperative enteral nutritional support for prophylactic stoma. In the case of malignant tumors of the large intestine, the stoma needs to be retracted about three months after surgery. In the case of malignant lesions of the intestine, enteral nutrition during the perioperative period can replenish the nutrients needed by the body and has relatively few complications. In addition, after surgery, patients should be advised to eat less and more often, not to overeat, to eat more coarse fiber food, and to have regular fiber colonoscopy review.
