Acute appendicitis is one of the most common acute abdominal conditions in clinical practice. The indications for non-surgical treatment of appendicitis in general are mainly as follows: i. Adolescent patients have mild pain symptoms in the appendix area, mildly elevated infection indexes by blood tests, and no appendix with fecal stone impaction detected by ultrasound examination. In this case, conservative anti-infection treatment can be given, and most patients can have local inflammation completely controlled after 3-5 days, and pain symptoms can be gradually relieved. Second, for elderly and frail patients, often combined with coronary heart disease and cerebral infarction, even if the diagnosis of acute appendicitis is confirmed, the risk of surgical treatment is greater, and patients may experience heart failure or recurrent cerebral infarction after surgery, so it is also recommended that patients take conservative treatment methods. Patients with acute appendicitis have been suffering from the disease for a long time and have localized abscess formation around the appendix. In this case, the appendix cannot be surgically removed, and only conservative anti-infection treatment can be chosen. Forced surgical removal of the appendix may result in serious complications such as intestinal fistula.
