Amputation of one section of intestine may have sequelae such as postoperative infection, short bowel syndrome and anastomotic rupture. 1. Postoperative infection: If the doctor operates improperly, takes care of the patient improperly, or sterilizes the instruments incompletely during the operation, it may lead to the invasion of bacteria and viruses into the body, resulting in postoperative infection. Symptoms usually include bleeding and pus in the wound, and a few patients also have fever. 2. Short bowel syndrome: patients with intestinal amputation may have intestinal absorption dysfunction, resulting in short bowel syndrome, patients may suffer from malnutrition, weight loss, diarrhea and other adverse symptoms. 3. Anastomotic rupture: Because the blood supply at the anastomosis in the intestines is more abundant, it may lead to arterial rupture and symptoms of anastomotic rupture, which usually leads to abdominal infection and edema of the intestinal wall. It is recommended that patients should maintain good dietary habits and go to the hospital regularly for rehabilitation checkups, and seek timely medical treatment when abnormal symptoms are found.
