Appendicitis

Treatment

If you have an uncomplicated case, a surgeon will remove your appendix soon after your doctor thinks you might have the condition. For information on this type of surgey see: appendectomy.

If the operation reveals that your appendix is normal, the surgeon will remove the appendix and explore the rest of your abdomen for other causes of your pain.

If a CT scan shows that you have an abscess from a ruptured appendix, you may be treated first and have your appendix removed after the infection and inflammation have gone away.

Outlook (Prognosis)

If your appendix is removed before it ruptures, you will likely get well very soon after surgery. If your appendix ruptures before surgery, you will probably recover more slowly, and are more likely to develop an abscess or other complications.

Possible Complications

• Abnormal connections between abdominal organs or between these organs and the skin surface
• Abscess
• Infection of the surgical wound
• Peritonitis
