The diagnosis of appendicitis is clinically based on the following indicators. The patient’s blood test may reveal a significant increase in leukocytes, neutrophil percentage, absolute neutrophil value and other indicators, suggesting an acute purulent infection in the patient. Second, through the appendix ultrasound or abdominal CT examination, it can be found that the appendix is enlarged with obvious blood eating, the appendix cavity is embedded with fecal stones, and the appendix is surrounded by obvious fluid accumulation. Third, the patient shows typical metastatic right lower abdominal pain, which is mainly manifested as pain around the umbilicus and under the glabella in the early stage of the disease, and the site of pain mainly shifts to the right lower abdomen in the later stage, while the patient shows fixed pressure pain and rebound pain in the right lower abdomen. The above indicators are very important basis for the diagnosis of appendicitis. Once a patient is considered to have acute appendicitis, it is recommended that the patient undergoes minimally invasive surgery under general anesthesia in an emergency, which is less invasive and has faster recovery after surgery, and can avoid serious complications such as septicemia, gangrene, perforation and periappendiceal abscess of the appendix.
