上海及全国一些地区胰腺炎流行病学调查

目的试用胰腺炎／胃癌住院病例比例和胃癌发病率，推测胰腺炎发病率。方法收集上海９家，其他地区９家医院共７９８３例胰腺炎住院病例。结果（１）上海市（１９８８～１９９５年）胰腺炎估计发病率为１８．６／１０万，男性１７．０／１０万，女性２３．０／１０万；（２）上海市（１９８８～１９９５年）胰腺炎占总住院比重３．８‰，其他地区７．４‰，为上海市的２倍；成都地区比重高达９．６‰；（３）性别分布：发病率女＞男；（４）年龄分布：男性年龄中位数为４９．５岁；女５７．０岁；（５）临床分型，胆源性占６３．１％，酒精性占１２．１％，不同于西方；（６）病前有暴食史者占１６．６％。结论胰腺炎的病因、诱因、危险因素虽不完全清楚，但与胆道疾病如胆结石、感染、饮酒、暴食、性别、年龄等有关。

An epidemiological study of pancreatitis in Shanghai and other regions

Objective To make a pilot epidemiological survey of pancreatitis in Shanghai and other regions. Methods A total of 7983 pancretitis cases were collected from 9 hospitals in Shanghai and another 9 hospitals in different regions in China. A new formula for estimating the incidence rate of pancreatitis was proposed, i.e. the ratio of hospitalized pancreatitis and gastric cancer the incidence rate of gastric cancer in that year. Results (1)The average estimated incidence rate of pancreatitis in shanghai from 1988 to 1995 was 18.6/105. (2)Hospitalized cases of pancreatitis in Shanghai (19881995) occuppied 3.8 the total number of admissions in these hospitals; 7.4 in other regions; and 9.6 in Chengtu; (3)Average female incidence rate of pancreatitis in Shanghai (19881995) was 23.0/105,higher than that of male (17. 0/105);(4)Age distribution: Median age of male pancreatitis patients was 49.5; while that of female, 57.0. (5)Risk factors included biliary disesses such as gall stones, cholangitis, etc., alcoholic consumption and eating and drinking too much at one meal. Conclusions (1)Method for carrying out an epidemiological study of a non-registered disease was suggested. (2)There were regional differences of pancreatitis and Chengdu might be a high endemic region.
