Appendicitis is a common disease. Common in surgery, mainly manifested as pain in the right lower abdomen. The main cause of appendicitis is the blockage of appendix lumen, such as lymphatic follicles, ascaris lumbricoides and obvious tumor proliferation. Because the appendix lumen is relatively thin, the opening is relatively small, the mesentery is relatively short, and the appendix lumen is curled, which is easy to block. The artery of the appendix is the terminal artery with colorless nevus. When the blood supply is blocked,

If bacteria invade the lumen of the appendix, it will hinder the arterial reflux and cause appendix ischemia and infarction. According to its clinical process and anatomical structure, it can be generally divided into four types: acute simple appendicitis, acute suppurative appendicitis, gangrenous appendicitis and perforated appendicitis, and periappendiceal abscess. Appendicitis is a common disease, and the typical abdominal pain mainly starts from the upper abdomen and then transfers to the navel, which is limited to the right lower abdomen.

Surgical resection is recommended after appendicitis, and conservative treatment is recommended if it is an abscess around the appendix.
