In clinical practice, the surgery of small bowel resection is considered a major surgery because there will be anastomosis of the gastrointestinal tract after small bowel resection. It will involve the anastomosis of the gastrointestinal tract, and the complexity of the operation is relatively high. Postoperative patients are also prone to complications such as abdominal infection, and even serious patients will have complications such as anastomotic fistula, causing further harm to patients. Therefore, after surgery, patients need to actively do preventive work, cooperate with doctors for intravenous nutritional support, symptomatic treatment, to change the incision regularly, and encourage patients to get out of bed as early as possible after surgery, which can help patients promote intestinal peristalsis. During the postoperative recovery period, patients should pay attention to eating less and more meals and avoid overeating, which can reduce the chances of intestinal obstruction after surgery.
