The most common cause of appendicitis attacks is peristalsis of the intestinal contents into the appendiceal lumen, which does not empty in time, resulting in appendiceal obstruction and a gradual increase in pressure in the appendiceal cavity, which can lead to restriction of venous blood flow and lymphatic flow in the appendiceal wall, and infection. In severe cases, purulent exudation from the abdominal cavity may complicate suppurative appendicitis and periappendiceal abscesses. Inflammation and infection may also occur in some patients due to an overly long appendiceal tract, after overeating or after strenuous exercise, which may affect the emptying of the appendix to some extent. Patients will show symptoms such as fever and abdominal pain. Therefore, it is important to pay attention to a reasonable diet, and early diagnosis of appendicitis should be promptly operated.
