After surgical treatment of small bowel perforation, how soon can the patient resume normal diet. Generally, we need to analyze objectively according to the different severity of abdominal infection and the different ways of intestinal perforation surgery. First, if the patient’s own healing ability is strong and the degree of abdominal infection caused by small intestinal perforation is mild, then choose laparoscopic minimally invasive surgery for small intestinal perforation repair. In this case, the patient’s trauma is relatively small, and the postoperative recovery is fast, generally in 5-7 days after surgery, the intestinal function is completely restored, and can eat normally. Second, if the patient’s small intestine perforation is large, causing serious abdominal infection, and the patient is old and frail, their own healing ability is not good. In this case, the traditional open surgery for intestinal perforation repair, in this case, the patient’s abdominal cavity infection is serious, will cause slow recovery of gastrointestinal function after surgery, generally need about 7-10 days to be able to normal diet.
