There is a probability of re-adhesion after surgery because adhesions form mainly after abdominal surgery or when there is infection, trauma, bleeding, etc. in the abdominal cavity. Adhesions can be between the bowel and an old abdominal wall incision, between the bowel and the bowel, or between the bowel and bowel loops. Regardless of the type of adhesion, when performing the release procedure, sharp separation should be used, to ensure that the bowel is as uninjured as possible to avoid rupture, and the separation of adhesions must be patient and meticulous enough to avoid rough intraoperative separations, which reduces the risk of severe adhesions in the postoperative period by minimizing the injury to the bowel. In the early postoperative period, in addition to aggressive correction of water electrolytes, large amounts of antibiotics and anti-anaerobic drugs should be given, such as cephalosporin combined with metronidazole, quinolone and so on. Early on, fasting and water should be used to reduce the pressure on the gastrointestinal tract and to ensure the patency of intra-abdominal drainage. In the postoperative period of 1-2 weeks, if the patient again occurs intestinal obstruction, at this time should be suspected of inflammatory exudation caused by adhesion, to make a diagnosis in a timely manner as soon as possible, active anti-inflammatory, growth inhibitors and corticosteroids, give intravenous nutrition and other methods of treatment, is not easy to reopen the surgery. Repeated surgeries can easily lead to irreversible adhesions, and the patient will die due to severe infection.
