The survival of patients after intestinal perforation surgery is related to the cause of the disease and cannot be generalized. Intestinal perforation is mostly caused by ulcer or tumor compression, and the main risk lies in the flow of intestinal contents into the abdominal cavity causing acute diffuse peritonitis, which mainly manifests clinically as symptoms of severe abdominal pain, and in severe cases, infectious shock or death. If the intestinal perforation is caused by simple inflammation, ulcer or benign tumor, active surgical treatment usually does not affect the survival of patients; if the intestinal perforation is caused by unresectable or metastatic malignant tumor, the survival of most patients is within 3-6 months because the tumor may progress; if the abdominal infection caused by intestinal perforation is not effectively controlled, it may cause multi-organ failure, which may endanger the patient’s life at any time. If the abdominal infection caused by intestinal perforation is not effectively controlled, it may cause multi-organ failure, which can endanger the patient’s life at any time. Patients with intestinal perforation must be operated early. After surgery, they should try to eat food that is easy to digest and absorb, avoid spicy, greasy and stimulating food, and eat more protein and vitamin rich food to promote body recovery.
