为了描述美国阑尾炎和阑尾切除术的流行病学，作者分析了1979-1984年的全国医院出院调查数据。在此期间，美国每年约有25万例阑尾炎病例，估计每年有100万个住院日。原发性阑尾切除术阳性（阑尾炎）的发病率最高的年龄为10-19岁（每年每10 000人中有23.3人）;所有年龄组中，男性阑尾炎的发病率均高于女性（总发病率比为1.4：1）。种族，地理和季节性差异也被注意到。白人的牙周炎发病率是非白人的1.5倍，最高（每年每10，000人中有15.4人）在西北部中心地区，夏季比冬季高11.3%。35-44岁的妇女意外阑尾切除率最高（每年每10 000人中有43.8人），比同龄男子的比率高12.1倍。在1970年至1984年期间，阑尾炎的发病率下降了14.6%;这种下降的原因尚不清楚。生命表模型表明，阑尾炎的终生风险为男性8.6%，女性6.7%;阑尾切除术的终生风险为男性12.0%，女性23.1%。总体而言，估计要进行36次偶然手术才能预防一例阑尾炎;对于老年人来说，偶然手术的预防价值要低得多。
To describe the epidemiology of appendicitis and appendectomy in the United States, the authors analyzed National Hospital Discharge Survey data for the years 1979-1984. Approximately 250,000 cases of appendicitis occurred annually in the United States during this period, accounting for an estimated 1 million hospital days per year. The highest incidence of primary positive appendectomy (appendicitis) was found in persons aged 10-19 years (23.3 per 10,000 population per year); males had higher rates of appendicitis than females for all age groups (overall rate ratio, 1.4:1). Racial, geographic, and seasonal differences were also noted. Appendicitis rates were 1.5 times higher for whites than for nonwhites, highest (15.4 per 10,000 population per year) in the west north central region, and 11.3% higher in the summer than in the winter months. The highest rate of incidental appendectomy was found in women aged 35-44 years (43.8 per 10,000 population per year), 12.1 times higher than the rate for men of the same age. Between 1970 and 1984, the incidence of appendicitis decreased by 14.6%; reasons for this decline are unknown. A life table model suggests that the lifetime risk of appendicitis is 8.6% for males and 6.7% for females; the lifetime risk of appendectomy is 12.0% for males and 23.1% for females. Overall, an estimated 36 incidental procedures are performed to prevent one case of appendicitis; for the elderly, the preventive value of an incidental procedure is considerably lower.
