The treatment period for intestinal obstruction varies from 2-3 weeks and varies from person to person. Incomplete intestinal obstruction recovers more quickly and usually improves in 1-2 weeks with conservative treatment, gastrointestinal decompression or induction enema. The most common cause of intestinal obstruction is still a history of open surgical treatment or a history of abdominal infection, and for intestinal obstruction caused by intestinal tumors, surgical treatment should be chosen to release the obstruction, and abdominal wall fistula can also be performed. In case of postoperative metastasis, recurrence and lymph node compression, intravenous chemotherapy can also be performed in this case. Strangulated intestinal obstruction can easily be complicated by necrosis or even infectious shock, so timely surgery should also be performed. Intestinal obstruction can easily be complicated by metabolic acidosis and disturbance of the internal environment, so regular monitoring of blood count and biochemical indexes should be performed during treatment.
