Appendiceal abscesses should be operated on after three months because of the risk of chronic appendicitis, recurrent attacks, or perforation causing peritonitis. In patients with acute appendicitis due to intestinal foreign bodies or bacterial infection, uncontrolled inflammation may lead to appendiceal abscess. Appendiceal abscesses should be surgically removed after three months, as chronic appendicitis can result from prolonged inflammation without surgery. An abscessed appendix should be operated on after three months because without surgery, the appendix may become septic and re-infected. This may lead to more severe abdominal pain as well as clinical symptoms such as fever, nausea and vomiting. If the appendix suppurates again and causes an abscess, it may also cause perforation of the appendix leading to peritonitis, which can seriously affect your health. After three months of appendiceal abscess, if you often have abdominal pain and other symptoms, you should go to the hospital in time, listen to the doctor’s advice, take reasonable and effective measures to treat, so as not to delay the condition.
