[Status report on epidemiology of acute appendicitis].
The current incidence of appendicitis is about 100 per 100,000 person-years in Europe/America. Whereas the appendectomy rate is still decreasing, the incidence of appendicitis is now nearly stable. During the last 30 years the incidence of perforated appendicitis has not changed (approximately 20 per 100,000 person-years). Established risk factors for acute appendicitis are age (peak: 10-19 years), sex, and ethnic group/race. Classical theories (diet, hygiene) present illuminating models to explain the rise and fall of incidence in the last century; however, from a contemporary perspective the evidence is insufficient. The study of the epidemiology of appendicitis is complicated by the influence of referral, infrastructure, and surgical treatment strategy on the incidence of acute appendicitis. Therefore, there is a strong need for good prospective studies with high-quality data (e.g., studies directed by a central pathology department).
