摘要
Background and Aims: Aging with comorbidities, obesity, and rapid recovery from operation may increase the need for laparoscopic cholecystectomy, but long-term use of statins may be associated with a decreased risk of gallstones. This population-based cohort study presents the changing rate and causative factors of laparoscopic cholecystectomy in Finland during the era of statin use. %26lt;br%26gt;Materials and Methods: Age structure of the population, changes in body mass index and diabetes, and the number of all cholecystectomies in 1995-2009 were retrieved from the registers of National Institute for Health and Welfare. Additionally, these results were supplemented by a population-based retrospective cohort (1581 laparoscopic cholecystectomy) in one community-based hospital area. The risk factors for laparoscopic cholecystectomy, use of statins, and surgical outcome were analyzed. %26lt;br%26gt;Results: During the 15 years, 123,794 cholecystectomies were performed in Finland, of which 94,740 (76.5%) were performed using laparoscopic technique. The median rate of laparoscopic cholecystectomy varied between 110 and 140 operations per 100,000 inhabitants. In 1995-2009, the annual number of cholecystectomies decreased from 8600 to 7500, the number of laparoscopic cholecystectomies increased by 10%, and the number of open cholecystectomies declined by 60%. In a cohort of 1581 laparoscopic cholecystectomies, the proportion of elderly (%26gt;65 years of age), obese (body mass index %26gt;30 kg/m(2)), and diabetic patients increased from 17% to 28%, 9% to 34%, and 4% to 8%, respectively. Use of statins increased more than fourfold during the 15 years. %26lt;br%26gt;Conclusions: The rates of all cholecystectomies decreased despite marked increase in laparoscopic cholecystectomies performed. The increase in risk factors for gallstones in Finland implied more marked increase in laparoscopic cholecystectomies. The possible role of statins on gallstone disease is discussed.
