Fifth-day syndrome

　　Fifth-day syndrome is also known as the fifth-day syndrome after pediatric appendectomy.. The etiology of fifth-day syndrome is not yet clear. Some people believe it may be caused by immune deficiency and weakened defense mechanisms.

　　When the fifth day syndrome develops to a certain stage, especially when it causes obstruction, it can trigger a series of symptoms. Including weakness, anemia, unexplained weight loss, persistent abdominal pain, and so on.

　　The clinical manifestations of the fifth day syndrome are as follows:
　　1. The course of the disease is short, and there are no true signs of peritonitis.
　　2. The operation process was smooth, and there were no abnormalities during the operation, and the incision was not infected.
　　3. Sudden abdominal pain, high fever, and peritonitis symptoms appeared on the fifth day after surgery.
　　4. Conservative treatment can quickly relieve symptoms, and no abnormalities are found during reoperation.

　　Since the fifth day syndrome occurs after appendectomy in children, preventing appendicitis is the basic measure for preventing this disease. In addition, children should generally be discharged after the 6th day to avoid missing the diagnosis of the fifth day syndrome and delaying treatment.

　　The diagnostic methods for the fifth day syndrome include CT, blood routine, and X-ray examination, mainly for differential diagnosis, and attention should be paid to differentiate from diffuse peritonitis.If the blood routine shows microcytic anemia, the erythrocyte sedimentation rate is accelerated, and the occult blood test in the stool is continuously positive; X-ray manifestations include barium filling defect, rigid intestinal wall, decreased or absent peristalsis, irregular colon pouches, intestinal stricture or dilation, etc., it can be diagnosed as having the fifth day syndrome..

　　Dietary注意事项 for fifth day syndrome patients:
