Appendicitis is a very common clinical disease with a higher incidence in young people and more men than women. The main causes of acute appendicitis are bacterial infections, damage to the appendiceal mucosa from various causes, and bacterial infections in the appendiceal lumen can cause appendicitis. The appendix is a relatively long and thin tube, and only one side is connected to the cecum. If there is an obstruction of the appendiceal lumen, it can lead to increased secretion in the lumen, increased pressure, and compression of the appendiceal canal wall, which can cause appendiceal blood flow obstruction. Patients with appendicitis can develop metastatic right lower abdominal pain with fever, nausea, and vomiting. Patients with such symptoms should go to the hospital to improve the relevant tests to clarify the diagnosis, and those diagnosed with appendicitis can be treated surgically.
