Can a burst appendix be treated without surgery?

No, a burst appendix cannot be treated without surgery. When the appendix bursts, it spills its contents into the abdominal cavity, which leads to peritonitis, a serious infection of the abdominal lining. This can be life-threatening if not treated promptly. Surgery is necessary to remove the appendix and clean the abdominal cavity to prevent the spread of infection. Antibiotics may also be given to help fight the infection.
