Thus appendicitis is now considered by some to behave as two distinct disease processes, typical and atypical (or suppurative). Approximately two-thirds of patients with appendicitis have typical histories, and findings suggest a virus or mild obstruction as a cause. In the third with atypical histories, an early suppurative process begins at the clinical onset, and severe unremitting obstruction is the likely cause. In any case, early surgical removal is the best treatment for either type of appendicitis. (Hobler,K., 1998)
