How is appendicitis treated now?

Surgical Removal. There is a growing body of literatures that supports medical (antibiotic) treatment for appendicitis. This literature is mainly from europe, and is a reflection of their particular medical system. The issue is that appendicitis is definitively treated by surgical intervention (appendectomy) with minimal risk. However, some cases of appendicitis can be cured by antibiotics with a failure rate.
Nonsurgical approach. There is an increasing body of data supporting the use of antibiotics, bowel rest, and drainage of abscesses in acute appendicitis, with some debate regarding weather or not to remove the appendix later.
