The number of operations for biliary stone disease in Sweden has decreased. To assess the changing incidence of gallstone disease, the numbers of gallstone operations and positive and negative cholecystograms occurring in a defined population over a 10-year period were studied. Both investigations showed a highly significant decrease; the cholecystectomy rate was reduced to 57% of that at the beginning, and the proportion of pathological cholecystograms to 35%. The proportion of normal X-ray findings increased over the 10-year period, and a larger proportion of the patients with radiologically confirmed gallstone disease were operated on. The incidence of pathological cholecystograms is considered to be of particular significance with regard to prediction of the incidence of symptomatic cholelithiasis. It is concluded that the incidence of symptomatic gallstone disease decreased during the period studied.
瑞典胆石病手术数量有所下降。为评估胆石病发病率的变化，对特定人群在10年期间发生的胆石手术数量以及胆囊造影阳性和阴性结果进行了研究。两项调查均显示出高度显著的下降；胆囊切除术率降至开始时的57%，病理胆囊造影的比例降至35%。在这10年期间，正常X线检查结果的比例有所增加，并且在经放射学证实患有胆石病的患者中，接受手术的比例更大。病理胆囊造影的发生率在预测有症状胆石症的发生率方面被认为具有特别重要的意义。得出的结论是，在所研究的期间，有症状胆石病的发病率有所下降。
