A review of the 202 patients admitted to Nottingham hospitals with primary acute pancreatitis during the six years 1969-74 has been undertaken. The City of Nottingham and the four adjacent former urban districts had a population of 469 720 in 1971, and an attempt was made to obtain details of all patients from within this defined population area. 134 of the 202 patients came from this area. The annual incidence varied by 4-fold throughout the six years of the survey from a peak incidence of 83-0 per million population in 1974 to a low incidence of 21-2 per million in 1970. There was no detectable pattern behind this variation and consideration of the individual figures did not suggest that any particular predisposing factor accounted for the variation. Spatial variation analysis is now being undertaken to see if population and environmental subgroups can be identified.
对1969年至1974年这六年期间入住诺丁汉医院的202例原发性急性胰腺炎患者进行了回顾性研究。1971年，诺丁汉市及四个相邻的前市区人口为469,720人，并试图获取该特定人口区域内所有患者的详细信息。202例患者中有134例来自该区域。在整个六年的调查中，年发病率变化了4倍，从1974年每百万人口83.0的峰值发病率到1970年每百万人口21.2的低发病率。这种变化背后没有可察觉的模式，对个体数据的考虑也没有表明任何特定的诱发因素导致了这种变化。目前正在进行空间变异分析，以确定是否可以识别出人群和环境亚组。
