Conservative treatment is needed for intestinal obstruction after abdominal surgery, and if conservative treatment is ineffective or recurrent intestinal obstruction occurs, surgery can be considered again. Because intestinal obstruction occurs after abdominal surgery usually includes three types: First, inflammatory intestinal obstruction occurs in the early postoperative period around 1-2 weeks because of serious abdominal infection, and most of them have a good prognosis after treatment with fasting, gastrointestinal decompression, anti-infection and rehydration, and no obvious serious complications will remain. Second, about 1-3 months after the operation of adhesional intestinal obstruction, the same early conservative treatment, fasting, gastrointestinal decompression, anti-infection, rehydration and other symptomatic treatment, most of the symptoms can be relieved and even cured. Third, the formation of adhesion bundles in the abdominal cavity leads to recurrent episodes of adhesive intestinal obstruction and more frequent episodes, which seriously affects the quality of life and nutritional status of patients. Therefore, in the case of recurrent intestinal obstruction, surgical release of adhesions is required to obtain a cure.
