If there is an inflamed appendix, it needs to be removed by an operation urgently. An inflamed appendix may rupture leading to infection in the entire abdomen (peritonitis), which may be life-threatening.
The operation to remove the appendix is known as appendectomy. It can be done through a mini-incision in the abdomen (known as mini-laprotomy) or through a laproscope. It is a minor procedure. In children, it is done under general anesthesia. Surgery leaves behind a minor scar. Recovery occurs within 7-10 days.
