Mesenteric torsion is most often seen in developmental abnormalities and is more common in children. Patients may experience significant abdominal pain, abdominal distention, nausea, and vomiting. Due to the compression of the mesenteric vessels, the blood supply and blood return to the intestinal canal are affected. If necessary, surgical treatment is required to reset the mesentery or to surgically remove part of the mesentery and intestinal canal. During conservative treatment, active anti-infection therapy, intravenous fluid supplementation, monitoring of changes in internal environmental indicators, and prevention of ion disorders and acid-base imbalance should also be taken into account. In some patients, the symptoms gradually improve with conservative treatment, but there is a possibility of recurrence. During the treatment period, the main thing is to observe the changes of abdominal symptoms and signs. If there are obvious signs of peritoneal irritation, such as pressure pain, rebound pain and muscle tension, the possibility of intestinal necrosis is not excluded, and in this case, we should actively choose to perform a caesarean section and surgical treatment.
