Acute appendicitis is associated with abdominal pain, the severity of which is directly related to the extent of the inflammation. If the inflammation is mild, the abdominal pain can be tolerable. However, if there is significant pus in the appendix or perforation, it can cause severe abdominal pain, similar to being cut by a knife. Acute appendicitis generally requires surgical treatment. Currently, a common procedure is laparoscopic appendectomy, which causes less bleeding during surgery and allows for a quicker recovery with minimal damage to the body. For patients who cannot tolerate general anesthesia, spinal anesthesia can be used, and the appendix can be removed through an incision at McBurney's point.
